Status changed to 'Confirmed' because the bug affects multiple users.

[oldfred (oldfred)]

Installing Kubuntu noble-desktop-amd64.iso as of 2024 March 05.

Error says main.py but related to networking.

Main script file /usr/lib/x86_64-linux-gnu/calamares/modules/networkcfg/main.py for python job networkcfg raised an exception.

Graphics show Lubuntu during install before crash.

Then desktop crashes both after install crash or with Try Kubuntu.

The upstream fix for this is here:
https://github.com/calamares/calamares/commit/5568d22549384a092a0d294d7343840d186839c6

To implement it in situ, edit /usr/lib/x86_64-linux-gnu/calamares/modules/networkcfg/main.py so that line 158 reads like:
                os.chmod(f.fileno(), 0o600)
instead of its current state of:
                os.chmod(f, 0o600)

Tested manual workaround identified by wxl (Upstream Fix) on Lubuntu Daily Build 07.03.24 on the Dell Wyse 3040 (See Related Bug #2054697) and this workaround resolves failed installation allowing it to complete correctly.

[Jane Atkinson (irihapeti)]

Can confirm that the fix above also works on Kubuntu ISO 20240308.

[Eugene San (eugenesan)]

Still exists as of build 20240311 and workaround from https://bugs.launchpad.net/ubuntu/+source/calamares/+bug/2054795/comments/4 works.

[Aaron Rainbolt (arraybolt3)]

For the record, the fix for this bug is uploaded (I believe), but it's stuck in the -proposed pocket because of a giant change happening at the same time (the time_t64 transition for avoiding the Year 2038 problem). It may be a bit before we see ISOs with the fix on it.

[ԜаӀtеr Ⅼарсһуnѕkі (wxl)]

The fix is in 3.3.5-0ubuntu1. Because of that time_t64 issue, you can't simply enable the proposed repo and install it, though.

The 'fixed' 3.3.5-0ubuntu2 is now migrating to the release pocket.
