view story

http://ubuntuforums.org – Hi, after fsck I got the problem that I cannot delete the file /usr/bin/boincmgr due to suspicious ownerships. See yourself: Code: 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 No need to mention that there is no group 256. When I try to delete/change the file I receive: Code: cdrewing@cdrewing-desktop:/usr/bin$ sudo rm -f /usr/bin/boincmgr [sudo] password for cdrewing: rm: Entfernen von »/usr/bi (Hardware)
