ooops upgrading buster -> bullseye

[aces and eights]

upgrading buster to bullseye answered "keep old config" to a few things now roundcube is not working. Install I was using was from roundcube source not debian.

I try to purge roundcube and start again,.

but there are messages.

--------

I thought that the database was MarianDB but maybe not.

How do I get rid of what causes the error and start again ?

apt purge roundcube roundcube-core
rm -rf /etc/roundcube
apt install roundcube

That said, unless you absolutely love roundcube, you might want
to look into alternatives. Although it's not packaged in Debian,
snappymail -- https://snappymail.eu/ -- is easy to install and
very good. The license is AGPL, so it could be packaged (and
probably should be.)
