Package: dpkg
Version: 1.15.5.6
Removal of package gnokii-cli 0.6.28.dfsg-1 left
/var/lib/dpkg/statoverride in a corrupted state (LP#537025, debbugs
#563317):
$ grep gnokii /var/lib/dpkg/statoverride
root gnokii 4750 /usr/sbin/mgnokiidev
$ ls -l /usr/sbin/mgnokiidev
ls: cannot access /usr/sbin/mgnokiidev: No such file or directory
$ grep gnokii /etc/group
$ dpkg-statoverride --remove /usr/sbin/mgnokiidev
dpkg-statoverrides: unrecoverable fatal error, aborting:
syntax error: unknown group 'gnokii' in statoverride file
$ dpkg-statoverride --list
dpkg-statoverrides: unrecoverable fatal error, aborting:
syntax error: unknown group 'gnokii' in statoverride file
The "corrupted state" here is that the statoverride file mentions a
group which no longer exists. (The same issue occurs with a
nonexistent user, as see in LP#161798
Problems with this:
1. Parsing of /var/lib/dpkg/statoverride should not require the users
& groups to exist. Those are separately maintained databases; also,
couldn't statoverride be referring to a file which may or may not
exist and whose user/group identity might be maintained dynamically?
2. This is not a "syntax error" but an "unexpected value".
3. The error should not be fatal for --list.
4. The error should definitely not be fatal for an attempt to --remove
the very entry which is being complained about!
5. Trivial: the message should not be prefixed with
"dpkg-statoverrideS", which is neither the name of the utility nor of
the data file.
To reproduce without the help of a defective package:
# sudo sh -c 'echo "foo bar 1234 /etc/baz" >> /var/lib/dpkg/statoverride'
# dpkg-statoverride --list
