Hmm, that’s interesting.

  1. It seems that systemd doesn’t have permissions !? to mount filesystems
  2. You don’t seem to have squashfs support in your kernel. Does it work if you modprobe squashfs
  3. Your snapd is slightly out of date (2.32.5 is the most recent release)

I honestly don’t know what to say. Did snaps work for you before? Is this a recent issue?

unfortunately i’m a noob here that’s why manjaro and not sure what is squashfs.

from my understanding snap is like docker for linux apps so i tried using that to not break the system dependencies as the apps i want isn’t maintained by manjaro community

Squashfs is a type of filesystem that is required to use snaps. Snaps are little filesystems that are mounted instead of being unpacked (like inserting a virtual CD into a virtual CD drive)

problem solved install snapd-git instead

That is surprising (to say the list) as snaps-glib is a library that talks to snapd over an UNIX socket. Maybe it pulled in some dependencies?

just to update apps installed but some app can’t launch e.g brackets while some can spotify

Some snaps, those that use so-called classic confinement are not isolated from your system (or vice versa) so they can often fail if not prepared correctly. Normal snaps don’t have this issue but certain class of applications, e.g. text editors would give poor experience with confinement today.

snapd-git, not snapd-glib
