Has anybody managed to install Ubuntu 25.04?

When I boot up the Ubuntu 25.04 ISO file, then all I see is this:

Also, launching “Install Ubuntu 25.04” does absolutely nothing !!!

Not even an error message :weary:

Tried all ISO builds available here, but they all show the same problem:
https://cdimage.ubuntu.com/daily-live/

Any help will be welcome…

Yes, I know that this is a pre-release version. But isn’t the purpose of a pre-release version to identify (and fix!) problems, especially critical ones like this, before the release date ?!?!

Regards.

is your system a X86 (aka AMD64) or Arm processor?

is your system a X86 (aka AMD64) or Arm processor?

It is an AMD64 (Ryzen 9 5950X) processor with 64 GB of RAM and a GeFroce RTX 3070 Ti.

Yes, and the expectation towards people installing it is that they report these problems, especially if the bug report tool already prepared everything for you and you only need to click the “Send” button now :wink:

Note that feature freeze was only very recently, the stabilization phase has only begun…

The last daily build I tested was about one week ago and installed no problem.

Have you tried starting in safe graphics mode?

you only need to click the “Send” button now :wink:

Guess what I did. Like 10 times now. This will make the window freeze for like 5 minutes, and then it goes away with no further information or anything. Did it actually send anything? I have no idea. Especially, launching “Install Ubuntu 25.04” does absolutely nothing! It Does not even show the “Sorry…” dialog. I tried opening a terminal, but to no success either :weary:

Yes. One difference is that there are no Desktop icons. Also no error message right at the start. But when I click the “Install” icon on the top of the left side bar, it will only make the UI disappear for 1 second and then re-appear. Then… nothing. No installer. No error message.

…just nothing :face_with_diagonal_mouth:

Just to confirm, is this the daily build you tried?

Yeah, tried every “25.04” ISO file that is currently available, including that one.

But the problem is always the same.

Yes that is the point however you seem to be expecting someone to hand you a fix immediately so you can go on with your installation and running. In some cases with pre release software you will hit a wall. The only choice is to send a bug report then wait. You will likely not get a response or anything, it will come down a normal update then it will be fixed. I don’t recall how the bug tool works but you should be able to track it somehow on Launchpad I believe.

Then, put it on hold, reboot into a working installation and continue about your day until you decide to try again hoping that the update was pushed.

Patience is a very big thing in testing pre release stuff. Sometimes there is nothing you can do but wait… that is unless you have both the desire and ability to fix it yourself and push a patch upstream. Not many can do that.

Ubuntu 25.04 installer is currently broken: Bug #2097559 “Installer crash w Segmentation fault (core dumped)...” : Bugs : subiquity
the updated version will be in the next good ISO but ISOs have not been created for a few days
ubuntu : Live filesystems : “Ubuntu CD Image Team” team.
You must wait for a new ISO with the new installer.
I’m writing from Plucky 25.04 installed a few days ago before the problem and is working fine.
If you launch the installer from terminal with “snap run ubuntu-desktop-bootstap” you will see the error messages.

Thank you. That is the information I was looking for!

At least I now know what is the matter…

Launching a terminal is not possible either. Just nothing happens…

Nope, I don’t expect an immediate fix. What I do expect, though, is that, if no fix is currently available, someone either confirms my problem as a known problem that is being worked on, or that someone confirms that this is a new problem and that they add it to their backlog.

You may launch the terminal with Ctrl+alt+t
Fix to my bug is currently available but can’t be tested because a new ISO is not available. If you want you may open the link to my bug and click on ‘affect me’

That seems to work, though it takes ages for the terminal to show up.

So your problem is the same as my bug Bug #2097559 “Installer crash w Segmentation fault (core dumped)...” : Bugs : subiquity so wait with me.

Not sure how well that works in a live session, but if the fixed Installer is already out there you could try a
sudo snap refresh ubuntu-desktop-bootstrap
And in case that works, try to launch it again…

installer updates itself, there is no need to refresh but installer is not self-containing so perhaps other external components are missing.

sudo snap refresh ubuntu-desktop-bootstrap

This actually worked to make the installer start. Installation seemed to succeed too.

…but after the reboot Ubuntu won’t come up.

It’s just showing a “black” screen with an “X” shaped cursor showing up (and disappearing) every few seconds. After a while, it just remains completely black.

Already tried running “apt update” from the recovery mode. It updated quite a few packages, but the “black screen” problem still remains.


Update - After a while I see this:
