yep, that's exactly what's needed to allow the old `roundcubemail-core` 
package to be removed. This is a bug in the package's `prerm` maintainer 
script.

Unfortunately, I'm currently out of ideas how to fix this automatically. 
Shipping a fixed version of the old `roundcubemail` package won't work, 
because `apt` will simply ignore that version, because it is being replaced 
with an even newer version anyway...

So, for now, the best solution is this:
edit `/var/lib/dpkg/info/roundcubemail-core.prerm`, comment out the line with 
`reload_apache`, then perform the package upgrade.

Could you try running `apt update` to get the latest package sources? That 
particular dependency problem should have been fixed last night with version 
1.5.2-0~kolab4.

Not sure what the concrete problem is here, but I would avoid Debian 11 for 
now - the removal of Python 2 means that pykolab won't work correctly. There 
is some ongoing community work to make pykolab compatible with Python 3, but 
it's rather slow-moving because that's not an easy feat at all. The devil is 
in the details.

Best,
Christoph
