[Bug 1825655] Re: do-release-upgrade fails with "Your python3 install is corrupted" if /usr/bin/python points to /etc/alternatives/python
I tested this by installing python2 on an Ubuntu 19.04 system then symlinking /usr/bin/python to /etc/alternatives/python - an empty file but that's fine. I then ran 'do-release-upgrade' and received the error message in the description. I then ran 'do-release-upgrade -p' and the upgrade proceeded. ** Tags removed: verification-needed verification-needed-eoan ** Tags added: verification-done verification-done-eoan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825655 Title: do-release-upgrade fails with "Your python3 install is corrupted" if /usr/bin/python points to /etc/alternatives/python To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1825655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have configured using -proposed packages like documented in https://wiki.ubuntu.com/Testing/EnableProposed.

Shouldn't is be Package: * Pin: release a=disco-proposed Pin-Priority: 400 as I am still on disco?

Hello Dmitrii, or anyone else affected, Accepted ubuntu-release-upgrader into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source /ubuntu-release-upgrader/1:19.10.15.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: ubuntu-release-upgrader (Ubuntu Eoan) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-eoan -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1825655 Title: do-release-upgrade fails with "Your python3 install is corrupted" if /usr/bin/python points to /etc/alternatives/python To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1825655/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In your case, the error message is *accurately* reporting that you have corrupted your python3 system install. /usr/bin/python3 and /usr/bin/python are not alternatives in Ubuntu, and changing them to be so is unsupported.
