[Bug 1964328] Re: Lubuntu Installer unmounts luks volumes during install resulting in failed mountpoints for installer
The way I read this, this is the software working as intended. There's
no reason to manually do all the partitioning and encrypting.
** Changed in: calamares (Ubuntu)

Title:
Lubuntu Installer unmounts luks volumes during install resulting in
failed mountpoints for installer
Status in calamares package in Ubuntu:
Invalid
Bug description:
When trying to install lubuntu on custom created luks volumes.
The installer unmounts the luks volumes by that removing the FS inside
them and fails to install.

This error was allso present in 20.04.
I spent the last two years hoping it would be fixed.
But i decided i might as well report it this time since 22.04 is
coming up soon.

Hope this is all that is needed to reproduce it
