TL;DR I had moved my /root directory onto the /home partition to ensure its contents are respected (too) between reinstalls. Snap notices stuff like that and won’t go along with it.
$ sudo snap install gimp
error: cannot perform the following tasks:
- Run install hook of “gimp” snap if present (run hook “install”: cannot perform operation: mount --rbind /root /tmp/snap.rootfs_XOSjpI//root: Permission denied)
I, as root, would like to know just what process thinks “it” can deny(?), Me, permission(?) to, well, anything, anywhere on My machine. (So I can kill it. A lot. And then pour salt on it.)
Other than that, I’m completely over it and could use some advice how to proceed.
# ls -lRa /tmp/snap.rootfs_XOSjpI/ total 8 drwx------ 2 root root 4096 Apr 10 06:54 . drwxrwxrwt 28 root root 4096 Apr 10 06:55 ..
