I expect "frontend" to be "/usr/share/debconf/frontend" and therefore that you have another update (still) running somewhere, waiting for you to answer a question from debconf.
I like to look at the output of "ps faux" to get more context into what has started process. You can either "ps faux | less" and "/frontend", or soemthing like "ps faux | grep -B 4 -A 1 frontend" (show 4 lines Before and 1 line After the match). -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssl in Ubuntu. https://bugs.launchpad.net/bugs/2008846 Title: package libssl3:amd64 3.0.2-0ubuntu1.8 failed to install/upgrade: installed libssl3:amd64 package post-installation script subprocess returned error exit status 1 Status in openssl package in Ubuntu: Incomplete Bug description: encounter error when attempting to do sudo update, upgrade, and full- upgrade ProblemType: Package DistroRelease: Ubuntu 22.04 Package: libssl3:amd64 3.0.2-0ubuntu1.8 ProcVersionSignature: Ubuntu 5.15.0-58.64-generic 5.15.74 Uname: Linux 5.15.0-58-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu82.3 Architecture: amd64 CasperMD5CheckResult: pass Date: Wed Mar 1 10:28:26 2023 ErrorMessage: installed libssl3:amd64 package post-installation script subprocess returned error exit status 1 InstallationDate: Installed on 2022-10-01 (150 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) Python3Details: /usr/bin/python3.10, Python 3.10.6, python3-minimal, 3.10.6-1~22.04 PythonDetails: N/A RebootRequiredPkgs: Error: path contained symlinks.
