Antergos - IceWM and no entries in the menu after upgrade - mmaker no suitable terminal emulator found

After doing an upgrade of my Antergos VM with an IceWM, I've lost all relevant entries in the menu.

"No problem" I thought, "i just need to recreate them" and did it with >>mmaker -f icewm<< but nothing was generated. Actually, the file >>~/.icewm/menu<< was missing totally.

After running things again and having an eye on the output, the mmaker was telling me:

mmaker no suitable terminal emulator found

After searching around, the quickest solution was to install >>xterm<< and rerun the menu creation again to solve this issue.

archzfs has a new key and a new maintainer for the unofficial arch linux user repository

The unofficial but great archzfs build has a new maintainer and most important, a new key.

#pacman-key -r F75D9D76
#pacman-key --lsign-key F75D9D76

And you are ready to upgrade. The key was changed since they are now using a buildbot to reduce the time between new kernel release and adapted archzfs package. Thanks for your great work people!

It just happens on my Rasperry pi: signature from "Arch Linux ARM Build System <[email protected]>" is unknown trust

I've started a regular update by using sudo pacman -Syyu and the following lines where the final result.

warning: Public keyring not found; have you run 'pacman-key --init'?
downloading required keys...
error: key "77193F152BDBE6A6" could not be looked up remotely
error: required key missing from keyring
error: failed to commit transaction (unexpected error)
Errors occurred, no packages were upgraded.

I did what was told me to do ;-).

sudo pacman-key --init

And after running sudo pacman -Syyu I was asked.

:: Import PGP key 4096R/68B3537F39A313B3E574D06777193F152BDBE6A6, "Arch Linux ARM Build System <[email protected]>", created: 2014-01-18? [Y/n]

"As expected, I though" but than I got a long list of the error mention in the headline (for each package).

I've fixed this by executing the following command.

pacman-key --lsign-key 77193F152BDBE6A6

After that, sudo pacman -Syyu was running fine as expected. Strange note, all was working fine a week ago (2018-05-25) and the pgp key was created 2014 :-O.

"amixer: Mixer attach default error: No such file or directory" when try to start blockify or blockify-ul

You want to start blockify-ui or blockify on a pulseaudio served arch linux and get the following error?

amixer: Mixer attach default error: No such file or directory
Traceback (most recent call last):
  File "/usr/bin/blockify-ui", line 11, in <module>
    load_entry_point('blockify==3.6.3', 'gui_scripts', 'blockify-ui')()
  File "/usr/lib/python3.6/site-packages/blockify/gui.py", line 972, in main
    _cli = cli.initialize(__doc__)
  File "/usr/lib/python3.6/site-packages/blockify/cli.py", line 597, in initialize
    cli = Blockify(_blocklist)
  File "/usr/lib/python3.6/site-packages/blockify/cli.py", line 63, in __init__
    self.channels = self.initialize_channels()
  File "/usr/lib/python3.6/site-packages/blockify/cli.py", line 184, in initialize_channels
    amixer_output = subprocess.check_output("amixer")
  File "/usr/lib/python3.6/subprocess.py", line 336, in check_output
    **kwargs).stdout
  File "/usr/lib/python3.6/subprocess.py", line 418, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command 'amixer' returned non-zero exit status 1.

Try to call "amixer" first and check the output. The chance is high that it will be something like the follow:

amixer: Mixer attach default error: No such file or directory

How to fix this?

Install the following tools: * extra/pulseaudio-alsa * extra/alsa-utils * extra/alsa-plugins * extra/alsa-lib

After that, amixer should output something meaningful and blockify should work as expected.

JDownloader and spontaneous core dump

JDownloader was working properly and than you just get core dumps all over again? Best try, upgrade your Java Runtime Environment.

sudo archlinux-java status
sudo pacman -S jre9-openjdk
sudo archlinux-java set jre9-openjdk
#if not needed anymore
sudo pacman -R jre8-openjdk

You need to update the $PATH variable. Either you restart your system or you open a new terminal to start JDownloader from their. All should work fine now.

arch linux error: key "CEB167EFB5722BD6" could not be looked up remotely

On some machines, I get the following error when I run an "pacman -Syyu".

error: key "CEB167EFB5722BD6" could not be looked up remotely

I've found the best fox so far on this page.

#open /etc/pacman.d/gnupg/gpg.conf as root
#comment out existing server address and replace with following
#save the file afterwards
http://pool.sks-keyservers.net

#run following command as root
pacman-key --refresh-keys

#if the upgrade is still not working, signed the key (be aware to know what you are doing here!)
pacman-key --lsign-key CEB167EFB5722BD6

This was working on almost all machines. Only a few percent where still not able to be upgraded. What I did to fix this issue was to copy the the directory in "/etc/pacman.d/gnupg" from a working host to the not working one (make a backup first of course).

Firefox 56 to 57, my changed list of essential extensions to gain back freedom on the broken internet

Well, after ages and lots of donated money to the extension developer (yes, I do an you should do the same!), mozilla made fundamental changes in ther way how to extend their browser. Because of that, I need to update my collection of extensions.

Firefox 57? Thats the browser where you have to open "about:config", search for "pocket" and set the value to false for "extension.pocket.enabled" and "browser.toolbarbuttons.introduced.pocket-button". You also have to disable all the spam on your blank start page (new tab). And of course, disable and remove all cliqz related shit.

Here is my new list working with firefox 57. Lets see how well things are working out. The mozilla extension search results are as bad as google search results today.

  • AdBlocker for YouTube
  • HTTPSEverywhere
  • Open With
  • Tree Style Tab
  • Tree Style Tab Mouse Wheel
  • uBlock Origin
  • uMatrix
  • Disconnect
  • Vim Vixen or Tridactyl
  • Empty Cache Button
  • Tab Suspender
  • Quick Accept-Language Switcher
  • User-Agent Switcher
  • I don't care about cookies
  • Cookie AutoDelete

For the log, here is my old list working in firefox 56.

  • BarTab Lite
  • AdBlocker for YouTube
  • HTTPSEverywhere
  • Open With
  • Tree Style Tab
  • uBlock Origin
  • uMatrix
  • Disconnect
  • Cache Status
  • checkCompatibility

aur/teamviewer 12.0.85001 is not starting anymore on an arch linux system

Just had the "joy" to figure out that teamviewer is not starting anymore on my arch linux.

I restarted the deamon and also launched teamviewer from the command line.

Init...
CheckCPU: SSE2 support: yes
XRandRWait: No value set. Using default.
XRandRWait: Started by user.
Checking setup...
Launching TeamViewer ...
Launching TeamViewer GUI ...

And at "Launching TeamViewer GUI ..." that was it, no entries in an error log or the journal, nothing. After having a look into the aur package log, it quickly turned out to be a solvable problem.

wget https://archive.archlinux.org/packages/l/lib32-freetype2/lib32-freetype2-2.8-2-x86_64.pkg.tar.xz
sudo pacman -U lib32-freetype2-2.8-2-x86_64.pkg.tar.xz 

Looks like teamviewer decided to use an old and deprecated version of freetype2 within his bugfix release.

How to update your arch linux without the kernel

If you are using archzfs and the zfsonlinux, you know that it can happen from time to time that you have to wait until packages are updated to the newest kernel (or lts kernel). Whenever you want to upgrade your system, you get an error like the following.

:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: spl-linux-lts: installing linux-lts (4.9.32-1) breaks dependency 'linux-lts=4.9.30'
:: zfs-linux-lts: installing linux-lts (4.9.32-1) breaks dependency 'linux-lts=4.9.30'
:: zfs-utils-linux-lts: installing linux-lts (4.9.32-1) breaks dependency 'linux-lts=4.9.30'

To update your system without the kernel (and its dependencies), you can use the following trick.

#example if you use the lts kernel
#if you use plain pacman
pacman -Syyu --ignore=linux-lts,linux-lts-headers
#if you use pacaur
pacaur pacman -Syyu --ignore=linux-lts,linux-lts-headers

Thats it :-).

How to upgrade the bios of a lenovo x250 on linux (and other not windows systems)

So, you want to update the bios of your lenovo x250 by downloading this iso from that page?

Read this readme. But also read the following lines. Lenovo missed "just some little facts".

First of all, I was not able to dump that iso to an usb stick by using dd. Secondly and most importatn, you have to go in your bios setup and change your boot up way from "legacy" to "uefi". After you have done that, your burned optical disk will boot up and you can finally upgrade your bios.

Display problems LibreOffice 5.* used in Gnome 3.20 on Arch Linux

There was a problem with LibreOffce 5.* used in Gnome 3.20 on an Arch Linux with the 4.4.*-lts kernel. The Display that is used is a HDPI so I am not sure if this is the reason.

Anyways, the problem was that the menu, all the menu entries as well as the font and the content was displayed with four or up to eight the size. If you want to click on something, there was a minimal size lane of size you could go but all in all, it is not a joyful ride.

I could not really find a search term that pointed me to the solution so I tried a lot.

At the end, the only thing that was working is to switch the gnome backend from Wayland to X11. dcdriving from the arch linux forum gave me the hint. How are you doing this?

  • open the file /etc/gdm/custom.conf
  • uncomment the line "WaylandEnable=false"

Hope you will stumble upon this entry and it will solve your problem

X11 freezes and system total hang up on an Lenovo X250 i7-5600U since kernel 4.6.2 (arch linux)

Hey folks, since kernel 4.6.2 I got a lot of X11 freezes as well as unusable gui tools (delayed inputs, scrolling and broken display rendering). Also all the virtual box clients are behaving the same. Only the chromium gui and xterm were usable (well, xterm only on my host, not on the virtual box clients).
I tried my best and here are the changes I made that stopped the system from a total freeze since four days:

run as root

cat /etc/X11/xorg.conf.d/20-intel-graphics.conf < DELIM Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "uxa" Option "NoAccel" "True" EndSection DELIM

I am crossing fingers it is working on your machine also.

Automatic setting of your multi display setting

So you have an X server running with multiple displays (or monitors).
You are using the great arandr tool to quickly setup your setting. But, you don't want to do this each time you are starting your X.
What can you do?
First of all, hit the "Save As" button in you arandr gui and store the shell script.
Afterwards, adapt the file that is read once you login into your system or start your X. This can be .xinit, .login or .profile.
Inside this file, simple add the adapted content from below and thats it.

maybe you have to change the path ".screenlayout" or the file name "default.sh"

if [ -f $HOME'/.screenlayout/default.sh' ]; then

speed up your owncloud by using redis on an uberspace webspace

Your owncloud is a bit slow, you are using uberspace and you want to speed it up easily?
Easy solution is to use redis.
The compressed howto is down below. It is taken from the uberspace wiki and a privat blog entry.


test -d ~/service || uberspace-setup-svscan
uberspace-setup-redis
svc -du ~/service/redis

to prevent or fix the following error "Missing memcache class \OC\Memcache\Redis for local cache"

uberspace-install-pecl redis

Last but not least, you have to adapt your /config/config.php file by adding and adapting the following lines into the configuration array.

    //...
    //begin of redis configuration
    'memcache.local' => '\OC\Memcache\Redis',
    'redis' => array(
        'host'      => '/home//.redis/sock',
        'port'      => 0,

virtual box "5.0.4" bridged networking connection issue between guest and host (windows 10)

Since we spent days (let me write it again, daaayyyyyyssss) to solve this problem. To prevent you from doing the same, I write this entry.
Our problem was, that a guest box was running fine on a virtual box host. The "only" issue was, that everyone could ping (and even do more) with the host and the guest os, except the host talking with the guest and vice versa.
It looks like this is a microsoft windows 10 issue only. Everything is workin on my *nix systems - meaning, if you are using real software, no problem is there.
But seriously folks (I know you are not reading this entry because you want to have some funny battle from good, free as in freedom software, against clunky ugly and bad close source whatever), the solving of this issue is braindead simple.


It a also contains a workaround: 
- Open the network adapters in Windows 10
- Open properties of the adapter used in your guest OS
- Disable IPv6 -> OK
- Open properties again
- Enable IPv6 -> OK

"Taler", das Open Source und Free as in Freedom Online-Bezahlsystem wird entwickelt

Unter dem Schirm von GNU wird an einem freien Online-Bezahlsystem mit dem Namen Taler entwickelt.
Der Unterschied zu Bitcoin ist, dass man nur die Menge an Geld, aber nicht die Ware sehen kann, um Steuern zu berechnen. Darüber hinaus ist der Geldaustausch von Sender zu Empfänger anonym. Das Protokoll ist offen, somit kann jeder seine eigene Implementierung schreiben. Es ist REST-basiert und nutzt damit die Stärken des HTTP-Protokolls. Es ist nicht als neue Währung ausgelegt, sondern entspricht immer der aktuell gewählten Währung (und Umtauschkurse).

Taler ist ein neues elektronisches Zahlungssystem, welches bei Inria entwickelt wird. Zum heutigen Tag zeigt diese Seite die Vorteile unseres Systems auf. Im Laufe des Jahres 2015 sollen mehr Code sowie zusätzliche Dokumentation öffentlich gemacht werden. Voraussichtlicher Startpunkt des Zahlungssystems für den allgemeinen Gebrauch ist das Jahr 2016.

Entwickelt wird es von Institut national de recherche en informatique et en automatique (hier der Link zur deutschen Wikipedia).
