after fsck I got the problem that I cannot delete the file /usr/bin/boincmgr due to suspicious ownerships. See yourself:
No need to mention that there is no group 256.
cdrewing@cdrewing-desktop:/usr/bin$ ls -l boinc*
-rwxr-xr-x 1 root root 841992 Jul 18 19:24 boinc
-rwxr-xr-x 1 root root 227368 Jul 18 19:24 boinccmd
-rwxr-xr-x 1 root 256 4096 Mai 20 1986 boincmgr
When I try to delete/change the file I receive:
Note: Translated this means "rm: removal of '/usr/bin/boincmgr' not possible: The operation is not permitted"
cdrewing@cdrewing-desktop:/usr/bin$ sudo rm -f /usr/bin/boincmgr
[sudo] password for cdrewing:
rm: Entfernen von »/usr/bin/boincmgr“ nicht möglich: Die Operation ist nicht erlaubt
I even tried to remove the file using a LiveCD where I am receiving the same error. Even chown to root:root is not working.
Does anyone have an idea how to delete this file (as I want to make needed updates on boincmgr) without wiping my whole drive (and installing the system completely from scratch as well)?
Thank you for your help.
