It's not your .zshrc (which would be in your home directory) but the system's /etc/zsh/zshrc which has been deleted and tried to compare.
This issue seems though unrelated to the deletion of /etc/zsh/zshrc, with which at coped properly: Configuration file '/etc/zsh/zshrc' ==> Deleted (by you or by a script) since installation. ==> Package distributor has shipped an updated version. It seems not a zsh issue at all but a general release upgrade issue which just happened to happen while handling conffiles of the package zsh-common: *** zshrc (Y/I/N/O/D/Z) [default=N] ? d sh: 1: pager: not found diff: standard output: Broken pipe So for some reason, /usr/bin/pager (or /bin/pager or so) was not available during the release upgrade. /usr/bin/pager is usually /etc/alternatives/pager. Unfortunately, I have not really an idea against which package this could have caused. Reassigning to ubuntu- release-upgrader-core for now. ** Package changed: zsh (Ubuntu) => ubuntu-release-upgrader (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873423 Title: package zsh-common 5.8-3ubuntu1 failed to install/upgrade: conffile difference visualiser subprocess returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1873423/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
