Hello dear snapcraft people:) I having following issue with my snaps:

vld@pop-os:~$ sudo snap install hello-world
[sudo] password for vld: 
hello-world 6.4 from Canonical✓ installed
vld@pop-os:~$ hello-world
cannot perform operation: mount --rbind /mnt /tmp/snap.rootfs_KWU8Dh//mnt: No such device
vld@pop-os:~$ snap list | grep core
core                16-2.61.2        16928  latest/stable  canonical**   core
core20              20240227         2264   latest/stable  canonical**   base
core22              20240111         1122   latest/stable  canonical**   base

ENcountered this when my hugo stopped working. Went to the forum and was advised to test the above, see that it is a snap problem and when it was, was advised to come here:)) Thanks for help anybody:) Vladimir The Curious Mechanobiologist

Where is your home directory mounted ? It looks like its trying to access /mnt

I have a similar issue with a NFS share

Thanks @mc33 , my home is mounted in the default location from the beginning of the installation of !pop_os on a hard drive on an older laptop. The strange thing (for me) is, that it happened “overnight” without me changing the location of home or any settings. The hugo static site generator, which I am trying to learn to build a website, just stopped working.

Do you have any idea how to fix it? Should I just reinstall snap?

Best Regards Vladimir

I am not an expert on Snap, trying to fix my own issues with a NFS share and snap. Nothing to stop you trying as its broken.

Have you mounted a usb stick or hard drive in /mnt ? I wonder why its trying to look at mount point?

I dont know if you can turn on logs on snap and check /var/logs/*** ?

Hi @VladimirV.

Can you show the output of this command ?

mount
7

You can try this, follow these steps :


# Check snapd service
sudo systemctl status snapd

# If the service is down, execute this 
sudo systemctl start snapd

# Refresh snap
sudo snap refresh

# Remove `hello-word`, then install it
sudo snap remove hello-world
sudo snap install hello-world

# Again execute `hello-word`
hello-world 

# If the error persists, reboot your system
reboot

Thank you will try when I am at the computer:)

Well ! @VladimirV, try the scenario that I suggested to you (above in the thread) .

Hi thanks for the support,

tried the scenario, the problem pesrsits.

I also tried removing, and purging snap and snapd through apt, the same…

@VladimirV, I do not see errors in the log .

13

Hello thanks, yes there are no errors but when I try to run hello-world it hangs for a while and then closes with "sanity check timeout " (or something similar, sorry forgot to save the output) which is the same as before.

14

Okay, please show again the output when you execute hello-world .
