Public bug reported:
I'm trying to upgrade from Bionic to Fossa; I've had several problems
with do-release-upgrade that may all stem from the same issue.
I run "sudo update-manager" at the command line.
The system alerts me of a potential upgrade: "The software on this
computer is up to date. However, Ubuntu 20.04.1 LTS is now available
(you have 18.04)."
I click "Upgrade..."
I pops up the release notes window, but never populates it; it stays
empty, but otherwise correctly drawn, offering "Cancel" and "Upgrade".
In the command-line window is:
----------------------------------------
uranium@Hex:~$ sudo update-manager

/usr/lib/python3/dist-packages/DistUpgrade/DistUpgradeFetcher.py:23:
PyGIWarning: Gtk was imported without specifying a version first. Use
gi.require_version('Gtk', '3.0') before import to ensure that the right version
gets loaded.
from gi.repository import Gtk, Gdk
/usr/lib/python3/dist-packages/DistUpgrade/ReleaseNotesViewerWebkit.py:33:
PyGIWarning: WebKit2 was imported without specifying a version first. Use

from gi.repository import WebKit2 as WebKit
Gtk-Message: 09:10:22.336: GtkDialog mapped without a transient parent. This is
discouraged.
----------------------------------------
If I accept the upgrade anyway, despite that, it pops up another window
that appears to run do-release-upgrade and say it's downloading
something, before vanishing and being replace by one with the title
"Distribution Upgrade". That one doesn't draw properly--other than the
title bar, it's blank, and just grabs whatever's behind it, or whatever
was on a different desktop if I flip back and forth. On the command
line is:
----------------------------------------
authenticate 'focal.tar.gz' against 'focal.tar.gz.gpg'
extracting 'focal.tar.gz'
----------------------------------------
It never gets any further. If I click the close box, it hangs.
Eventually Metacity offers to kill it, which I accept. Nothing happens
in the command line when I do. Eventually I control-C it, and get this:
^CTraceback (most recent call last):
File "/tmp/ubuntu-release-upgrader-mv88pmez/focal", line 8, in <module>
sys.exit(main())
File "/tmp/ubuntu-release-upgrader-mv88pmez/DistUpgrade/DistUpgradeMain.py",
line 235, in main
save_system_state(logdir)

line 134, in save_system_state
universal_newlines=True).communicate()[0]
File "/usr/lib/python3.6/subprocess.py", line 850, in communicate
stdout = self.stdout.read()
KeyboardInterrupt
If instead I try to initiate the upgrade myself with do-release-upgrade,
I get this:
----------------------------------------
uranium@Hex:~$ sudo do-release-upgrade --allow-third-party
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [1,554 B]

extracting 'focal.tar.gz'

----------------------------------------
And then it never gets any further.
Ctrl-c gives me this:
----------------------------------------
^C
