Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Reading your report it appears you are mostly after support.

This bug report can be converted to a question (aimed at support, bug
reports are aimed and finding problems and fixing so subsequent users
won't stumble with the same issue).

The PPA you added to your eoan (19.10) system only supports bionic
(18.04), thus adding it was your mistake. PPA's are 3rd party
repositories, where it's your responsibility to ensure they were created
by a responsible party, are still maintained and are safe for your
system (now and into the future).

You then move to a different dependency issue, which again is support
related, and not a bug with software.

You can also find help with your problem in the support forum of your
local Ubuntu community http://loco.ubuntu.com/ or asking at
https://askubuntu.com or https://ubuntuforums.org, or for more support
options please look at https://discourse.ubuntu.com/t/community-
support/709
