No swap created when installing Xubuntu 24.04 iso.

[ajgreeny]

I installed Xubuntu 24.04 using the graphical installer from the iso file downloaded on Dec $th 2023.

All went well but no swapfile was created at install.

The installation replaced a partition with Xubuntu 20.04. It was installed using the Something Else option at installation and choosing te 20.04 partition for the / partition of the new version. The existing EFI partition was used.

I anticipated a swapfile would be created automatically but this did not happen causing suspend failure on lid closure of the laptop which is what it is set to do.

This is was found originally on Noble, Xubuntu, 231209.

I used Noble, daily, 20231210 -- installed twice,with two different slight variations.

Fist was Other / Manual, using existing partitions, no re-format. Second was on newly created partitions from unallocated space.

Both resulted in not creating a swap file:

The third test-case, I installed with an existing swap partition, which it did recognize that it existed, and the installer used it as a swap partition... So this issue seems to be localized to not creating a swap file, if an existing swap partition does not exist...
