"Install alongside another OS" option is missing from Kubuntu installer

[Omer I.S.]

At the disk partitioning section, there is no option to install Kubuntu alongside another OS, but the Ubuntu installer does have this option.

Reverting status to 'New' as requested information added by reporter.

[Omer I.S. (omeritzics)]

Guess this would be fixed when the current installer will be replaced by the flutter one...

[Launchpad Janitor (janitor)]

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

There is still no way to install 22.04 in dual boot with windows on an encrypted partition without having to use the command line.
