I have a few NFS mounts via autofs, and when one of them times out, I get an error like this when i try to launch a Snap
Oct 13 16:48:38 Y4M1-II-UbuntuUnity-KVM steam_steam.desktop[12294]: cannot create mount point /tmp/snap.rootfs_xjlsJH//mnt/nfs/data: Permission denied
The message would show up when launched via terminal, but if launched from the app launcher, there’s no error window.
