This type of error typically occurs because the cached .pyc files are out of date for some reason. (C.f. https://www.py4u.net/discuss/17141, https://stackoverflow.com/questions/30861493/how-to-fix-python- valueerrorbad-marshal-data)
This specific issue is occurring not in python-cryptography itself, but rather in the /usr/bin/py3compile call when its trying to import debpython. In other words, something's inconsistent with your system's cached python code. It sounds like perhaps force reinstalling python3-minimal might be worth trying. ** Package changed: python-cryptography (Ubuntu) => python3-defaults (Ubuntu) -- 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/1935783 Title: package python3-cryptography 1.2.3-1ubuntu0.3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 Status in python3-defaults package in Ubuntu: New Bug description: would not install updates ProblemType: Package DistroRelease: Ubuntu 16.04 Package: python3-cryptography 1.2.3-1ubuntu0.3 ProcVersionSignature: Ubuntu 4.10.0-28.32~16.04.2-generic 4.10.17 Uname: Linux 4.10.0-28-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.30 Architecture: amd64 Date: Sun Jul 11 15:16:59 2021 ErrorMessage: subprocess installed post-installation script returned error exit status 1 InstallationDate: Installed on 2021-07-11 (0 days ago) InstallationMedia: Ubuntu 16.04.3 LTS "Xenial Xerus" - Release amd64 (20170801) RelatedPackageVersions: dpkg 1.18.4ubuntu1.7 apt 1.2.35 SourcePackage: python-cryptography Title: package python3-cryptography 1.2.3-1ubuntu0.3 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) package:python3-cryptography:1.2.3-1ubuntu0.3 Setting up python3-cryptography (1.2.3-1ubuntu0.3) ...
