I'm afraid I can't walk you through resolving a broken upgrade in a bug report, it's just not the best medium for the job. Nor can I see a troubleshooting guide that I can recommend.
The process is that you need to complete the apt upgrade. Usually this involves something like: # dpkg --configure -a # apt-get -f install # apt-get upgrade # apt-get dist-upgrade And fix any issues a long the way, until you can get things to complete. In the example above, removing or upgrading eric would probably allow python 3.8 to configure. If you're out of your depth, I'd recommend taking a backup and re- installing. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python3-defaults in Ubuntu. https://bugs.launchpad.net/bugs/1957199 Title: package python3 3.8.2-0ubuntu2 failed to install/upgrade: installed python3 package post-installation script subprocess returned error exit status 4 Status in eric package in Ubuntu: New Status in python3-defaults package in Ubuntu: New Bug description: failure when trying to upgrade to Ubuntu 20 ProblemType: Package DistroRelease: Ubuntu 20.04 Package: python3 3.8.2-0ubuntu2 ProcVersionSignature: Ubuntu 4.15.0-166.174-generic 4.15.18 Uname: Linux 4.15.0-166-generic x86_64 NonfreeKernelModules: nvidia_uvm nvidia ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: skip Date: Wed Jan 12 11:28:01 2022 ErrorMessage: installed python3 package post-installation script subprocess returned error exit status 4 InstallationDate: Installed on 2015-08-26 (2330 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) Python3Details: /usr/bin/python3.8, Python 3.8.10, python3-minimal, 3.8.2-0ubuntu2 PythonDetails: /usr/bin/python2.7, Python 2.7.18, python-is-python2, 2.7.17-4 RelatedPackageVersions: dpkg 1.19.7ubuntu3 apt 2.0.6 SourcePackage: python3-defaults Title: package python3 3.8.2-0ubuntu2 failed to install/upgrade: installed python3 package post-installation script subprocess returned error exit status 4 UpgradeStatus: Upgraded to focal on 2022-01-12 (0 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eric/+bug/1957199/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
