DPKG or APT General Errors¶
This is a general catch-all doc for any smaller errors you might come across involving the
dpkg installation systems.
Sometimes, for a reason unknown to me, you’ll get an error while installing, updating/upgrading - what have you - about the
statoverride file having an unknown user:
For me, it usually happens after uninstalling a program - which makes sense, seeing as something extra has decided to hang around in our installation program files.
The specific file that is giving us issues is
How To Fix¶
There are 2 different ways I found to remove the extra bit of info from the offending file, of which, both require you to at least see the contents of the file:
– or –
sudo nano /var/lib/dpkg/statoverride
The second option is the first way we can fix this issue, by removing the offending information, which in the above case - StatOverride File - the issue is about
cockpit-ws. Below is the output of the
root postdrop 2555 /usr/sbin/postqueue root sasl 660 /etc/sasldb2 postfix postdrop 2710 /var/spool/postfix/public root root 4755 /usr/sbin/mount.davfs root crontab 2755 /usr/bin/crontab root sasl 710 /var/run/saslauthd root mlocate 2755 /usr/bin/mlocate root root 1733 /var/lib/php/sessions root ssl-cert 710 /etc/ssl/private root messagebus 4754 /usr/lib/dbus-1.0/dbus-daemon-launch-helper root cockpit-ws 4750 /usr/lib/cockpit/cockpit-session root postdrop 2555 /usr/sbin/postdrop
You can see the line that includes
cockpit-ws above. If you have the above file open in your text editor, you can simply delete that line out, and rerun your prior apt command again.
The second way to fix it is a more official way, using one of dpkg’s commands, dpkg-statoverride - which makes even more sense….
dpkg-statoverride --remove /usr/lib/cockpit/cockpit-session
For this one - and ironically, this is the ONE item that makes NO sense - you have to use the path that is listed in the file, rather than the specific “user” that &apt errors out with… And thats why I’m using this option as my second fix, because its more or less an extra step after viewing or editing the
statoverride file above.
