Bug Description

This bug impacts revision 20 of ubuntu-desktop-bootstrap and while similar to the bug #2055372, it involves a different process crash that nevertheless produces the same result. On certain UEFI devices the python interpreter which the curtin process uses will crash when attempting to install the GRUB bootloader. This results in a failure to install a bootable OS.

This bug is still in effect as of revision 25. The software needs to use Python 3.12 instead of 3.10 to work correctly.

Hi,

Thanks for your report!

After reviewing #2055372, my initial suspicion is that they're both duplicate of #2055294, but I could be wrong. Could you also elaborate on how they are different?

> The software needs to use Python 3.12 instead of 3.10 to work correctly

Could you elaborate on why this is the case?

Thank you,
Chris

The bug remains in effect as of revision 29. In the last version of ubuntu-desktop-installer, the program worked properly under the 23.10 iso and installed GRUB as intended. The same program when tried on a 24.04 dev iso does not work properly due to problems with the python interpreter, mainly that the 24.04 iso uses a newer version of Python as default which is 3.12. The installer still uses version 3.10 on the snap file but then links to the system python that leads to the set of operations that produce the bug.

Update, Python is NOT the cause of the bug, but instead has to do with how the grub package was installed with a faulty process affecting the package that is described in bug #2055294. A fix has been committed according to the git repository but will have to test latest revision for confirmation.

Test confirms bug fix on latest dev iso, using revision 33, no further action is needed.
