Cannot perform operation: No such file or directory

#1

My system is Ubuntu 14.04.

I have several snaps installed, including vlc, gimp and libreoffice. In all three cases, when I attempt to run the applications, I am told:

cannot perform operation: mount --rbind /dev /tmp/snap.rootfs_dNQck6//dev: No such file or directory
(Different paths but always the same error.)

Gimp definitely worked when I installed it a few weeks back. I’m pretty sure libreoffice did too. I don’t know about vlc.

Thing I have tried which have not helped include rebooting, snap repair <snap> (“error: repairs are not available on a classic system”), snap remove <snap> and snap install <snap> (no change).

Nothing appears in tail -f /var/log/syslog | grep -i snapd when performing the failing operation.

#2

What’s the output of snap version and journalctl -u snapd?

Wow, a reply from the actual Popey :slight_smile:

Is /var/tmp a symlink to /tmp by any chance?

I’ve seen various reports of this error you’re getting, and it looks like a snapd bug. So we need someone from the snapd to help here.

How to run snap explicitly
#5

No, /var/tmp is a normal directory with the sticky bit set:

mark@laptop15:~$ ll /var
total 60
drwxr-xr-x 15 root root     4096 Jan 25  2018 ./
drwxr-xr-x 28 root root     4096 Nov 14 08:33 ../
[...]
drwxrwxrwt  4 root root     4096 Nov 14 09:00 tmp/
[...]

My system is old and battered (lots of things have been uninstalled, hacked around, reinstalled etc.). I’m not aware of anything (else) being broken, but I’m not ruling it out. If anyone would like logs etc, I’m happy to get them (if someone can point me at instructions).

Thanks!

#6

Have you been able to figure out what was causing this? I’m experiencing the same exact issue

#7

The problem is no longer happening but I do not recall doing anything to fix it, sorry.

I did increase the size of my / mount, which was previously quite full, and I have noticed a general improvement in how snaps are behaving. Perhaps it was related to that, but I’m really not sure.

#8

Are you sure? The issue was likely trying to use desktop snaps on 14.04. Is that what you’re trying to do?

#9

No @chipaca your right, this was the first post that I came across after searching for quite awhile that had the same exact error message I was getting when trying to start my snaps.
I’m running Arch Linux with the latest kernel:5.2.11 and I installed snap using the manual build process

$ git clone https://aur.archlinux.org/snapd.git
$ cd snapd
$ makepkg -si

as opposed to using $ yay -S snapd

I believe my issue was something along the lines as to what @popey had metioned

my snap version is

snap 2.42.1+18.04
snapd 2.42.1+18.04
series 16
ubuntu 18.04
kernel 5.3.0-40-generic

don’t know what’s causing this ?

#11

same issue, all snaps suddenly broken.
