I find it weird that Krita isn’t working for you… I have it installed on 4 different computers (all running different configs of Manjaro), and never ran into that issue.
What version of Manjaro are you running? I assume you downloaded the ISO from the main website.
It’s pamac-snap-plugin, not pacman-snap-plugin. It is a plugin for pamac, not a plugin for pacman. pacman doesn’t have snap support, but pamac does. pamac is a package manager created by the Manjaro Team that has both a CLI & GUI.
sudo pacman -Syu pamac-snap-plugin
Also, never use pacman -S, always use pacman -Syu to prevent partial upgrades.
I actually wonder if this was your issue. That you’re partially upgrading your packages, causing other applications to break. The only time pacman -S can be used if you 100% know that everything is in sync and upgraded already on your computer.
Did you run sudo pacman -Syu after you installed Manjaro?
Did you try to install it via sudo pacman -Syu snapd?
The package is snapd not snap.
Actually, from my personal experience, Manjaro and Arch-based Distros in general have more packages available than any other distro when using the official Repo and AUR. It’s one of the reasons why I started using Manjaro.
-
You can check if Manjaro has a package in it’s repo using the branch compare on the website or using
pamacor any other package manager on Manjaro itself. -
If the package doesn’t exist within Manjaro repo, you can check if AUR has the package.
-
If it doesn’t exist in Manjaro repo or AUR, then you can look at flatpak, snap, or appimage.
