aptitude update / upgrade broke my Rapbian bullseye
On Nov 26, I upgraded a Raspberry 4 from buster to bullseye using the
standard procedure of edit /etc/apt/sources.list and then apt-get
update && apt-get dist-upgrade. Everything went fine, it ran stable
for some days and one annoying bug in the openbox window manager
occured less often.
On Dec 1, I did aptitude update && aptitude full-upgrade and it found
lots of dependency problems. It seems this was mainly caused by
changing from gcc-8 to gcc-10 and python 3.7 to python 3.9. I accepte
the second suggestion to solve these problems, removing a couple of
packages, and the whole upgrade process seemed to work smoothly.
But on the following reboot, it showed lots of problems:
1. dhcpcd doesn't reliably get its config, /etc/resolv.conf remains
empty and the eth0 interface doesn't get an IP address.
2. Because of 1. NFS mounts fail
3. With restarting dhcpcd this gets fixed but after some time
(e.g. hours) dhcpcd fails again repeatedly with
dhcpcd[416]: ipv6nd_sendadvertisement: No buffer space available
4. Even when dhcpcd had success and the network is configured,
avahi-daemon for no apparent reason eventually changes the
interface address. From daemon.log:
Dec 4 20:04:50 <host> avahi-daemon[321]: Withdrawing address record for 10.0.0.8 on eth0.
Dec 4 20:04:50 <host> connmand[328]: eth0 {del} address 10.0.0.8/24 label eth0
Dec 4 20:04:50 <host> connmand[328]: eth0 {del} route 10.0.0.0 gw 0.0.0.0 scope 253 <LINK>

Dec 4 20:05:34 <host> connmand[328]: eth0 {add} route 0.0.0.0 gw 0.0.0.0 scope 253 <LINK>
5. Also connmand, which I hadn't in buster, continously logs messages
to daemon.log every few seconds:
Dec 7 05:48:34 <host> connmand[328]: Skipping server 10.0.0.254 KoD code RATE
Dec 7 05:48:43 <host> connmand[328]: Skipping server 10.0.0.1 KoD code RATE
Dec 7 05:48:52 <host> connmand[328]: Skipping server 10.0.0.1 KoD code RATE
Dec 7 05:48:57 <host> connmand[328]: Skipping server 10.0.0.254 KoD code RATE
Dec 7 05:49:06 <host> connmand[328]: Skipping server 10.0.0.1 KoD code RATE
6. The whole network seems unreliable.
7. A couple of changes in the GUI, which I don't care about much at the moment:
The Debian logo in the top left of the panel where you get the
start menu for app is replaced by a green arrow pointing left.
The small icons in the start menus to launch apps are missing
The entries in the panel for audio volume, network, and keyboard
language are missing.
8. I think there were some other minor issue which I currently don't
remember.
Now I wonder if there is a chance to get all these things fixed or if
a fresh re-install would be easier, faster, and more sucessful.
I think, first I should remove connmand, since I don't know what I'd
need it for.
