Up until around a week ago I was downloading kubuntu hirsute daily builds and installing with no problems.

Please run `apport-collect 1920712` from inside the installer environment after the crash happens.

Was this information not adequate?

I have attempted to install from

kubuntu hirsute daily build 21-03-22
kubuntu hirsute daily build 21-03-23
kubuntu hirsute daily build 21-03-24

each time the installation fails

The release of Ubuntu Gorilla had a bug which occurred when safe graphics mode was invoked at boot up time. This was marked as 'would not be fixed'.

When Kubuntu Hippo was released as a daily build there was no such bug, boot and install proceeded with no problem. It appeared that the bug had been dealt with.

At some point during March a 'safe graphics bug' reappeared, preventing booting or installation of Kubuntu Hippo.

Was this some sort of reversion in the boot process? Kubuntu is affected, Ubuntu is not. Did something happen to the build of Kubuntu in March?

I am not a programmer so will not be able to tackle this problem, though I wish I had the know-how.

I am willing to follow this and run tests on my hardware.

Although this bug is similar to one or two others, in this case boot from the install media does not proceed to a point where installation can be begun.

The other bugs reported seem to be on different hardware to mine. I suspect that in this regard this bug is unique.
I have an AMD m/board and an nVidia graphics card in a home built PC. My hardware does not usually throw up any problems in this way, but the use of safe grahics mode at start up is necessary.

Please leave this as a duplicate of #1920665 so ISO testers can find and report in just the single place.

I have been testing Daily Builds and more recently the Beta but since mid March no boot has been successful.
