  • Mount snap “discord” (121) (exit status 1)

pls help (if i need show more informations say me it in comments)

EDIT:
snap 2.39.3
snapd 2.39.3
series 16
solus 4.2
kernel 5.10.12-171.current

if you have any issues with snaps or snapd you should always include the full output of

snap version

so people can see what OS, kernel and snapd versions are currently running on your system.

i do it now you know how to fix it?
