lubuntu noble daily never starts.. black screen; Lubuntu box & Connecting..

[Chris Guiver]

Booted Lubuntu noble daily on
- hp prodesk 400 g1 sff (i5-4570, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

Multiple attempts made, each end in black screens, with a small window on one display titled "Lubuntu" and in the white window below it the word "Connecting..." and a light-dark-blue moving line that doesn't progress..

Multiple boots; and left for >15 mins (one attempt 25+ as I fed birds)

As I noted in testcase comment

at terminal I killed lubuntu-installer-prompt & I had a normal LXQt session appear...

At last resort (this issue maybe very rare; if its not transitory..) we can document how to kill lubuntu-installer-prompt as I did on discourse.. no need to mention in release notes even if this is done...

After this attempt, I next booted box below this one that uses same keyboard/screens etc & using same thumb-drive have no issues like this at all... no issue with this on
- hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600)

I wonder if this relates to video card?? (I'll try another box), then again the Connecting makes me (no doubt end-users) think of internet?? but I could `ubuntu-bug` file on the box so network makes little sense to me... ICMP echo requests (ping) to web are returned

This should be fixed in lubuntu-installer-prompt 24.04.4build1 once it migrates and an ISO builds against it.

[ԜаӀtеr Ⅼарсһуnѕkі (wxl)]

This is fixed in 24.04

lubuntu-installer-prompt (24.04.4) noble; urgency=medium

  * Fix a race condition where a wired network connection could hang the
    installer prompt during startup.

I left this as "Fix Committed" as the package that once migrated to the release pocket was removed and the package awaiting migration is still in the proposed pocket. The fix is not released yet, as it was unreleased.
