try to upgrade to jammy. Already with (20.4) full disk encryption. Installation abort with messaging lacking disk space

[Hugo Vargas]

MacBook Air 11"
Only has Ubuntu 20.04 (no other OS), fully encrypted
Processor: Intel® Core™ i5-5250U CPU @ 1.60GHz × 4
Disk: 1.0 TB
OS: Ubuntu 20.04.5 LTS
Gnome version 3.36.8
When running G-parted: Shows disk full with no free space

I was upgrading from 20.04 to 22 (Jammy)

When upgrading to Jammy, installation aborts with message saying there is not enough disk space.

There are more than 900 G available

I believe the upgrade is "reading" the available disk space from the wrong place

Thanks for all you guys do!

Thank you for taking the time to report this bug and helping to make Ubuntu better.

You've filed this bug as a problem with the linux 5.15 (20.04 HWE) kernel and not the Ubuntu release upgrader tool. The package used for the initial filing controls what details are useful for exploration of the actual problem, but no details were obtained relating to the release-upgrader-tool as you didn't file against that.

Bug reporting is mostly about finding & fixing problems thus preventing future users from hitting the same bug. It maybe better to classify this bug report as INVALID, and then file a new bug-report using `ubuntu-bug ubuntu-release-upgrader[-core]`, but I'll leave this report open, and suggest you seek support.
