[Solved] Unsatisfied Package Dependency After Kernel Downgrade

I am trying to install a package (zfs-linux-lts) which cannot satisfy a dependency, yet that dependency is for the kernel that I am currently booted into. The system is otherwise up-to-date except for the kernel, which I intentionally downgraded in an attempt to make this work. I downgraded it with

 pacman -U https://archive.archlinux.org/packages/l/linux-lts/linux-lts-6.6.36-1-x86_64.pkg.tar.zst 

Here is what I am seeing. Is pacman unaware of the kernel downgrade?

Arch Linux 6.6.36-1-lts (ttyS0)

-Syu updates the system, which also includes updating linux-lts to the current version (6.6.46-1). In other words: pacman is aware of the version more than you want it to be. You want to ignore the package update with `--ignore=linux-lts`.

Obligatory note on partial upgrades being unsupported. I do understand you probably need it only for testing and unupdated kernels are not generally frowned upon, but be aware this shouldn’t become the normal way your system operate.

Thanks! This fixed it

pacman -Syu zfs-linux-lts --ignore=linux-lts

The intentional downgrade is only needed for the install. Going forward, the kernel will just not update until the zfs package is updated for that kernel. Theoretically using LTS will reduce the frequency of this ZFS Installation. Hopefully this doesn't break later.

Hopefully this doesn't break later.

May want to take a look at: `IgnorePkg` in `man pacman.conf` to consider adding pkg/s to it.
