Without knowing the particulars of how you installed Chimaera or how
it's configured, it's going to be difficult to diagnose your problems.
However, the main problem is that you are using Chimaera which is still
in development, and that can introduce problems. Although, usually,
they correct themselves when the developers do the next round of
"fixes."

Did you do a clean install or upgrade from a previous version? IIRC,
you dist-upgraded from a Debian distro, but I've forgotten which one.
This can and does introduce problems even if done correctly.

Post your /etc/apt/sources.list and anything that is
in /etc/apt/sources.list.d/, too. If they are not set up properly,
that can cause problems.

How did you remove those packages?

No. Chimaera still being Testing shouldn't be a cause..

When using Testing, don't use apt-get upgrade, but only apt-get
dist-upgrade or apt full-upgrade. This is recommended when
running Testing instead of Stable. Upgrade by design won't install major
upgrades to apps, system files, etc. which can occur with Testing.
After Testing (Chimaera) becomes Stable, then use only apt-get upgrade
or apt upgrade. There are times when dist-upgrade needs to be used
to "fix" something, but we'll deal with that later.
