How can I remove a group (which was previously deleted) from a user which still references it? If I run
groups, I get an error about a non-existent group:
$ groups myuser dialout cdrom sudo dip plugdev fuse lpadmin sambashare groups: cannot find name for group ID 1001 1001
The usual way of using
deluser doesn't work because the group name no longer exists and there seems to be no flag for using IDs:
$ deluser myuser 1001 The group `1001' does not exist.
Is there a more straight forward way to remove a group (by ID) from a user other than by recreating the group, deleting the group from the user, and then redeleting the group?
