I have determined the the package was the ubuntu-release-upgrader
also if you read what I wrote properly you would see that there were no
messages: the entirety of gnome-shell was stuffed by the faulty upgrade,
all I had was a blank screen.
Fortunately I was able to login by ssh from my good machine and fix things on
the command line.
ok to format the data the way you want it.
1. The specific steps or actions you took that caused you to encounter
the problem.
I ran update-manager -d on a ubuntu 19.04 box and followed the
steps, there were some problems, in short the buttons of the upgrader
did not respond to the mouse, I used tab and enter to solve this.
2. The behavior you expected.
I expected the upgrader to cleanly upgrade my system.
3. The behavior you actually encountered (in as much detail as
possible).
The screen locked some way into the upgrade, I found it like this
during the night, I attempted to unlock it and after some time I was
confronted with a blank screen.
So I loggedin from my good machine by ssh, I found that the release
upgrader was still running but doing nothing as far as I could tell, I
gave it an hour, still nothing so I killed it using "sudo kill -1 pid1
pid2"; where pid1 was the pid of the of the python program doing the
upgrade and pid2 was a shell wrapper for it I think, I obtained these
pid's from "pgrep --full --list-full upgrade".
Then I rebooted the box with sudo shutdown -r +1 , when it came up again
I still had a broken box so I sshed in again, ran "sudo apt upgrade"
this failed but told me to run "dpkg --configure -a" as there was
stuffed messed up with the package system, (I forget it's exact words)
so I ran "sudo dpkg --configure -a" it installed many many packages
between 4000 and 5000 I think it exited cleanly but things still were
not right, I could login graphically again but gnome shell was still at
version 3.32.2 not 3.34 and some of the plugins were not working, so I
ran "update-manager -d &" again and it gave me a partial upgrader, but
that did not work.
So I ran "sudo apt-get dist-upgrade" that cleaned up some stuff and
deleted one package at least. then I ran update-manager and it pulled
down many more packages and fixed the system.
After all that I seam to be on a clean copy of 19.10:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu Eoan Ermine (development branch)
Release: 19.10
Codename: eoan
obviously this needs looking into before 19.10 proper comes out
