I upgraded to Ubuntu 22.04LTS from 20.04LTS.
Now it appears that the "mdadm" package is giving me hassles. Whenever I want to look for upgrades in terminal I get this error message:
Setting up mdadm (4.2-0ubuntu1) ...
dpkg: error processing package mdadm (--configure):
installed mdadm package post-installation script subprocess returned error exit status 20
Errors were encountered while processing:
mdadm
E: Sub-process /usr/bin/dpkg returned an error code (1)
How can I solve this problem??
sudo dpkg --configure -a
(which tells the package manager to configure all unconfigured packages) and look for more specific error messages. The issue may also already be solved by this command. – Jos Aug 21 '22 at 09:29
