what is the full output of snap version so we know what OS/kernel/snapd version you are on ?

EDIT: OOPS ! sorry i’m blind … that’s weird, it should show OS and kernel at least, could you give us that info (“cat /etc/os-release” and the output of “uname -a”) …

jamal_uddin · May 24, 2023, 1:19pm

And how do i check the “cat /etc/os-release”?

ogra · May 24, 2023, 1:21pm

just copy/paste what’s between the quotes into your terminal and hit enter

hmm, interesting, i do run the exact same setup on all my machines here without issue, is this in a VM, bare-metal, cloud ?

jamal_uddin · May 24, 2023, 1:23pm

It is a dual boot system with Windows 10

ogra · May 24, 2023, 1:24pm

was it an upgrade from a former ubuntu version or a fresh install ?

jamal_uddin · May 24, 2023, 1:26pm

I upgraded it from Ubuntu 20.04.

jamal_uddin · May 24, 2023, 1:27pm

It was 20 for sure. Not confident about the numbers after that though

ogra · May 24, 2023, 1:32pm

are the ubuntu-minimal and ubuntu-standard packages installed ? you can check with (copy/paste):

dpkg -l |grep -E 'ubuntu-minimal|ubuntu-standard'

if they are there (so all pre-requisites are fulfilled) i’d try to purge and reinstall snapd:

sudo apt purge snapd
sudo apt install snapd

and check snap version output again …

OUCH … looks like some firefox bug you are hitting there … the interesting part though is that “snap remove firefox” seems to not have complained at all, but just tried to remove the snap, lets try a snapd reinstall without removal (in the hope it overwrites potentially messed up stuff) …

there you go, there is something fishy with the state file, is your disk full, do you see any other filesystem errors in your system logs ?

jamal_uddin · May 24, 2023, 1:48pm

But my disk is showing that only 84.7GB is allocated

ogra · May 24, 2023, 1:52pm

this one is also worrying and points to some bigger underlying issue …

please check your system logs for any filesystem errors …

jamal_uddin · May 24, 2023, 1:54pm

ogra · May 24, 2023, 1:58pm

yeah, not what i meant … do not use the log viewer but something like journalctl from a terminal and look for suspicious errors … the log viewer is a nice toy but really not helpful in this case (but the GIO and Glib errors in there also look worrying, there seems to be something really wrong on the low level with your install)…
