Azure Ubuntu 18.04.5 LTS hit a bug when running 'do-release-upgrade'

[Wayne Lam]

I spun up an Azure instance of Ubuntu 18.04 LTS from Marketplace. I then ran 'do-release-upgrade' and it hit a bug. I then followed instructions on screen to report the bug, which then said:

Hi Wayne,

Thank you for reporting the issue.

I am able to reproduce it using this URN 'Canonical:UbuntuServer:18.04-LTS:latest'. By checking APT logs, the issue seems related to python2. Indeed, if I remove python2.7 (apt purge python2.7) before doing 'do-release-upgrade', the upgrade goes fine.

Thanks for taking the time to report this upgrade failure. There is currently a new version of the release upgrader available in -proposed which may resolve the error you've encountered. Please run the following command to test the new version of the upgrader:

  do-release-upgrade -p

Please lets us know the results in this bug report. Thanks again and good luck!

[Gauthier Jolly (gjolly)]

Indeed, this fixed the issue. I started a new bionic instance and ran

  do-release-upgrade -p

The process went as expected.

Thanks!

Thank you! I confirm it is working now.
