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 :-).

arch linux, zfsonlinx with pacman update producing error >>error: demz-repo-core: signature from "graysky (used to sign repo-ck packages) <[email protected]>" is unknown trust<<

You tried to do an update of your system and got some error like below?

pacman -Syyu
error: demz-repo-core: signature from "graysky (used to sign repo-ck packages) graysky@archlinux.us" is unknown trust
:: Synchronizing package databases...
[...]
error: demz-repo-core: signature from "graysky (used to sign repo-ck packages) graysky@archlinux.us" is unknown trust
error: failed to update demz-repo-core (invalid or corrupted database (PGP signature))
[...]
error: database 'demz-repo-core' is not valid (invalid or corrupted database (PGP signature))


You can read the comments if you want to know why.
If you are easy enough and believe me (well thanks, but you shouldn't ;-)), execute the following commands.
pacman-key -r 5EE46C4C
pacman-key --lsign-key 5EE46C4C
echo i like artodeto
pacman -Syyu


And there you go.
