Hi Sven, thanks.

$ apt policy

includes

Pinned packages:
[...]
gnome-control-center -> 1:3.30.3-2~deb10u1 with priority -30000
[...]

amongst other gnome components.

I had abandoned a previous gnome desktop installation because apt-listbugs had complaints about multiple components.  I hadn't realised it pins packages rather than just abandoning the installation if told to, although it does say so upon closer inspection :)

I deleted /etc/apt/preferences.d/apt-listbugs and approved the installation of

gnome-control-center
gnome-online-accounts

which succeeded, but:


Issue 1:

$ gnome-control-center online-accounts
**
ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid)
Aborted

$ gnome-control-center gnome-online-accounts
**
ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility: assertion failed: (valid)
Aborted

sudo gives the same result.  

This doesn't seem to relate to the bugs reported by apt-listbugs, which shows:

Retrieving bug reports... Done
Parsing Found/Fixed information... Done

Issue 2:

I tried to install task-gnome-desktop to see if it works with the full works installed, but even after deleting /etc/apt/pref*d/apt-listbugs and rebooting, apt-listbugs isn't offering the choice to install task-gnome-desktop but going straight to ("user-initiated") abort:

$ sudo apt install -y task-gnome-desktop | tee gnome.txt
[...]
Summary:

$ man apt-listbugs 

"... if any such bug is found, apt-listbugs warns the user and asks how to proceed ...

That is not the case here.


Fwiw...

$ cat /etc/apt/apt.conf.d/10apt-listbugs
// Before installing packages, check whether they have release-critical bugs.
// If you don't like it, comment it out.
DPkg::Pre-Install-Pkgs {"/usr/sbin/apt-listbugs apt";};

DPkg::Tools::Options::/usr/sbin/apt-listbugs::InfoFD "20";
AptListbugs::Severities "critical,grave,serious";
// AptListbugs::IgnoreRegexp "FTBFS";


Any advice on either issue much appreciated.

Many thanks,
Gareth
