Unable to run Install Lubuntu from desktop

[Leó Kolbeinsson]

Testing Lubuntu daily ISO dated 30.08.2023

Unable to run Install Lubuntu from desktop as the installer requires authentication (password).
However was able to run "Install system" from the menu but this resulted in a crash and failed installation.

Running "ubuntu-bug" also required password but but seemed to run in background.

see attached screenshot

This is likely due to the new polkitd dropping support for the old pkla (polkit local authority) files. Therefore, the lubuntu desktop seed likely needs polkitd-pkla seeded in order to use those old pkla files to avoid this.

Kubuntu ISO has the same issue launching ubiquity from the desktop icon

Indeed opening qterminal and installing polkitd-pkla before running the installer solves the issue, so it does seem to relate to the new polkitd.

When running install from desktop was asked for password - left the password blank and the install continued and completed normally with no errors.

Hoping for a better, more official solution once we get some clear instructions on how to properly write the authentication rules, but meanwhile I added polkitd-pkla to the Lubuntu live seed:

There's some hint of a more proper fix here:
