Can't install any snaps on Ubuntu 19.04

Hello,

When trying to install any snap, I get some variant of the following message:

(cannot setup udev for snap “”: cannot reload udev rules: exit status 2

example:
error: cannot perform the following tasks:

  • Setup snap “spotify” (41) security profiles (cannot setup udev for snap “spotify”: cannot reload udev rules: exit status 2
    udev output:
    )

I’ve tried a handful of different snaps, and they always fail the same way. This also happens when “core” is installed, but that one tends to work on the second try. I’ve read that repeating the install command might resolve this, but except for “core”, it never works for me.

I’ve tried the following snaps: vlc, spotify, anbox.

Troubleshooting steps I’ve tried:

  1. sudo apt purge snapd ; followed by reinstalling snapd (no change).
  2. testing udevadm control --reload-rules --log-level=debug (works normally, as expected, no errors).
  3. Reviewing journalctl -xe output for strangeness; no obvious errors jump out at me.

There is a little weirdness on my system, it is a systemd multiseat system using loginctl for seat0, seat1, and seat2, with 3 GPUs, 3 keyboards, 3 mice, and 3 monitors. But i’m not sure why that would cause an issue here.

Any help would be appreciated.

Thank you,

Sherwin Amiran
