[Bug 1824866] [NEW] python3-distupgrade missing a dep on python3-distro-info

[Brian Murray]

Public bug reported:

(bionic-amd64)root at impulse:/home/bdmurray/Documents/canonical/admin# do-release-upgrade
Checking for a new Ubuntu release
Get:1 Upgrade tool signature [819 B]
Get:2 Upgrade tool [1250 kB]
Fetched 1251 kB in 0s (0 B/s)
authenticate 'cosmic.tar.gz' against 'cosmic.tar.gz.gpg'
extracting 'cosmic.tar.gz'


A fatal error occurred

Please report this as a bug and include the files
/var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in
your report. The upgrade has aborted.
Your original sources.list was saved in
/etc/apt/sources.list.distUpgrade.

Traceback (most recent call last):

File "/tmp/ubuntu-release-upgrader-wvzfz5ou/cosmic", line 8, in
<module>
sys.exit(main())

File
"/tmp/ubuntu-release-upgrader-wvzfz5ou/DistUpgrade/DistUpgradeMain.py",
line 224, in main
from .DistUpgradeController import DistUpgradeController

File
"/tmp/ubuntu-release-upgrader-wvzfz5ou/DistUpgrade/DistUpgradeController.py",
line 25, in <module>
import distro_info

ModuleNotFoundError: No module named 'distro_info'

This a result of the SRU of the fix for bug 1799310 while the new
dependency was added to the cosmic version of u-r-u that doesn't help
because the dist-upgrader tarball doesn't reflect that dependency.
