When trying to install Budgie 25.04 with manual option no partition can be selected and formatted
Hi @agingskier!
Strange…
I’ve never encountered this problem, even though I systematically use “Manual partitioning” to keep control of what I’m doing.
It has to be said that I prefer to prepare my partitions with GParted from the live session, its interface and graphical representation being more user-friendly all the same.
Give it a try.
Thanks, I originally created all partitions with GParted. After that I try to do fresh installs with new versions to get rid of all the acumulated clutter. With version 24.04 the install with “Manual partitioning” worked like a charm. This time the installer does not accept to select any partition. I have one for /boot/efi, /boot, /, and /home. Neither /boot, /, or /home can be selected and formatted.
This really sounds like a new issue that Canonical needs to be made aware of.
Can I suggest in the live session run the following in a terminal to report it:
ubuntu-bug ubuntu-desktop-bootstrap
Started Budgie 25.04 in try mode, opened terminal and entered your suggested command.
It collected information and maybe sent the error report. But I got a message “no package found matching ubuntu-desktop-bootstrap”.
In the meantime I tried to “apt upgrade” to 25.04 and messed up the system. It seems very complicated to report a problem, so I give up and go back to 24.04 which perfectly.
@fossfreedom Same result for me the other day with ubuntu-bug language-selector-gnome:
Package language-selector not installed and no hook available, ignoring.
@agingskier Maybe your ISO is simply corrupt or the key has been flashed incorrectly: I’ve installed 25.04 several times without a problem, and again this morning — I’m using Etcher.
grrr … bug with ubuntu-bug …!
Always possible to have a corrupt ISO. I always used good old “dd” command like so: “sudo dd if=/home/bernhard/Downloads/ubuntu-budgie-25.04-desktop-amd64.iso of=/dev/sdf status=progress”
Never had a problem with this, but I will download the ISO file again and use Etcher instead to create the USB stick.
My understanding is that this one will be better: 
sudo dd if=/home/bernhard/Downloads/ubuntu-budgie-25.04-desktop-amd64.iso of=/dev/sdf bs=4M conv=fsync oflag=direct status=progress && sudo sync
I went through combinations. New ISO download,
create USB with dd command = no luck
create USB with dd command and additional options (bs and conv) = no luck
create USB with Etcher = no luck
Well, I had enough! Waiting for next Release.
Thanks for all your tests, @agingskier!
I don’t understand why you didn’t succeed, but it doesn’t matter: 25.04 is only a transitional release.
Hello.
I met a similar problem and found a workaround. Perhaps that will help you or someone else. Here are the details:
During installation of Ubuntu 25.04 with manual partitioning I got error “System program problem detected” on every attempt to assign a mount point to an existing partition:
I opened a terminal with <Ctrl> + <Alt> + <T> and checked content of folder /var/log/installer/.
ls /var/log/installer/
There was subiquity-traceback.txt there:
(CUT BY STUPID RULES. check one post below)
To read that file I needed sudo
sudo nano /var/log/installer/subiquity-traceback.txt
And the content was:
(CUT BY STUPID RULES. check two posts below)
“ValueError: edit_partition does not support changing partition name”
Content of the filesystem.py (line 1529) mentioned in the stack trace was:
(CUT BY STUPID RULES. That was not allowed because of limitations of number of posts. 
Good luck guys)
So… I performed a couple of experiments and the found workaround was:
- remove names from the existed partitions (for which you want to specify mount points in the installer) via GParted (important: name of the partition and not label of the filesystem)
- reboot computer and restart the installation (because it caches names of the partitions somewhere and without the reboot doesn’t work still)
Good luck.
Nicely diagnosed!
The best place though to file a bug report will be via GitHub - canonical/subiquity: Ubuntu Server Installer, and backend for Ubuntu Desktop Installer
You will need to tarball up /var/log/installer so that Canonical can confirm your resolution.
Cheers
With the latest findings, I had another go at the “Manual Installation”. This time I started from scratch. Created new partition table and new partitions for /boot/efi, /boot, / (root), /home and it worked. Could format all partitions and install Ubuntu budgie without a problem. Thanks everybody for helping.
