Problem installing phpMyAdmin on Ubuntu 19.10 (Eoan Ermine)
I am a member of the packaging team and we are doing our best to get back phpMyAdmin in the Debian buster repository ASAP (buster-backports), this will update Ubuntu afterwards.
You can use our PPA: https://bugs.launchpad.net/ubuntu/+source/phpmyadmin/+bug/1837775/comments/7
There is an open issue on our tracker for Ubuntu: https://github.com/phpmyadmin/phpmyadmin/issues/15515
And for Debian: https://github.com/phpmyadmin/phpmyadmin/issues/15236
Hope the PPA or installing manually using our website will help someone
To add the ppa mentioned by William Desportes and install phpmyadmin do the following:
sudo add-apt-repository ppa:phpmyadmin/ppa
sudo apt-get update
sudo apt-get install phpmyadmin
Obviously it has been removed for security reasons.
It popped up first in Debian Community: #916310 - 4.6 should not be shipped in a stable release - Debian Bug report logs
Then in Launchpad
Ubuntu Forums thread here: phpmyadmin missing from repository
It seems like some Debians joined the phpMyAdmin project to fix the problem in future releases.
Ubuntu "focal" 20.04 has now phpMyAdmin 4.9.2

Track progress for 19.10 (if some can be done) in https://github.com/phpmyadmin/phpmyadmin/issues/15515
