I just noticed it had bionic entries on sources.list when I was installing bridge-utils:
``` Start-Date: 2020-07-21 16:28:23 Commandline: apt install bridge-utils Requested-By: ubuntu (1000) Install: bridge-utils:amd64 (1.5-15ubuntu1) End-Date: 2020-07-21 16:28:33 ```
This is Bionic version, focal is 1.6-2ubuntu1, so after that I've replaced `sources.list` suite from bionic to focal.
