Thank you for providing the keyfiles as a reproducer! I think this line in the migration script [1] is failing here. We need to catch and handle the error. > ORIG_NAME=$(nmcli --get-values connection.id con show "$UUID")
The issue is, that this connection profile is apparently very old and doesn't get loaded into memory by modern NetworkManager anymore, therefor we cannot query NM about it. When trying to load it manually, I can see the following error in the journal: $ nmcli con load UPTOWN.guests $ journalctl -u NetworkManager -e NetworkManager[126986]: <warn> [1697527301.3708] settings: load: failure to load "/etc/NetworkManager/system-connections/UPTOWN.guests": filename is not valid for a keyfile [1] https://git.launchpad.net/network-manager/tree/debian/network-manager.postinst#n67 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/2039503 Title: package network-manager 1.44.2-1ubuntu1 failed to install/upgrade: installed network-manager package post-installation script subprocess returned error exit status 10 Status in network-manager package in Ubuntu: New Status in network-manager source package in Mantic: New Bug description: lunar to mantic upgrade, exciting to see output from network-manager postinst migrating connections to /etc/netplan one by one.
