I tried Ubuntu-22.06(?) for my raspberry pi 4 w/4G of ram. This is a popular small sbc with a 4 core Arm A-72 Cortex CPU. As all the different sbcs have different booting arrangements, Ubuntu do a binary image for each. You download to an sdcard/usb key and it has two partitions.

It booted exceptionally slowly, started through the basic config (What planet is this?) sort of thing. Then it crashed, crashed again trying to get diagnostics, and won't reboot. Quiet option on boot, Blank/Black screen. I'm burning it again. Any ideas?

I have all of rp1, rpi2, rpi3 and rp4. And I have never had an issue like this. Would be nice to know exactly what did you try to install and how and what hardware do you have? (if you have any addon or plugged in something, special config, whatever). Also if your power supply is good enough for that. I would first try a better power supply (3.5 A maybe).

I tried it on a usb key. I'll retry on an sdcard. Post again tmw.

I don't even want to think about what it was thinking/doing.

No addons, GPIO, etc. USB has a spare SSD disk, I've a keyboard/mouse thing, and one hdmi monitor.

I'm marking this solved because I can't say it's not hardware.

I bought 2 sdcards late last year and they're both apparently gone. I had distributions on each of them working fine, despite the fact that dd goes zombie after 10-11G. I tried to put the 7.4G of Ubuntu
on the "Good" one. Now the system doesn't recognize it's a disk. So I tried the usb key again, fsck & reinstall. It's slow as hell and never gets out of initial setup.

So I'll buy replacements and mark this Unsolved if Ubuntu is still found to puke on an rpi 4.

I got Ubuntu (Version 22.04.1 acutally) installed on a larger sdcard and usb adapter.

I do not want to lose any of my few friends here who like Ubuntu, so I'll reserve my opinions. But my problem was a dodgy sdcard. Thanks for help offered. I overwrote a working install on 2 newish micro sdcards, and to have them both die simultaneously was strange. The usb key that died also had a working install, but that was older equipment.

I like (K)Ubuntu on my desktops and such... Never tried it on my RPIs. I simply use PI OS as it meets my needs Ie. All that is needed to access the RPI systems and GPIO is included. I use the full PI OS or the small server PI OS. The server version for when I want to run headless. Note too that for 'full' install on RPI4, I usually use a Samsung T5 or T7 500GB as the OS drive (don't use >= 1TB, as RPI can't power the larger external drives unless through a powered usb 3.0 hub) and forgo the SD cards. Much faster boot time and application start times and 'reliable'. Big difference from the SD cards or thumb drives. I use Etcher to install the .img file.

That said, I saw this thread, but never responded as I don't have Ubuntu experience on the RPIs.

I installed Ubuntu all right. I tried installing vlc,but it kept tripping over it's dependencies, libc-bin to be precise. VLC would open a video but the screen wouldn't move.

I have this problem with RPi OS/Debian. I load it - fine. To add, I have to update it. When I do, I lose sound. I check, and everything is perfect in alsa & pulse. Still no sound comes. Slarm64 just works.

Interesting, sound has always worked for me (when I use it) in PI OS. I've used usb powered speakers or a usb->sound adapter which then allows me to plug in external powered speakers. Never used the 'onboard' speaker system. That said, I do remember I had to fiddle with a config file to set the default sound device that was being used. I've only one RPI4 system that actually uses sound which is used in a copy of the old Star Trek original series desktop computer I designed and built (looks something like this Star Trek Computer ). It needs the ability to 'talk' and make sounds when interacted with. I've also added a microphone, camera, and a IR sensor to tell when people are walking by... Ongoing fun project with possibilities.

That Star Trek Computer reminds me of my techie days - drilling holes in bits of folded metal that passed for a "box" and were sold for $$$ in Radio Shack and then soldering everything up. You ended up paying loads for a prototype that was just a POS anyhow.

Is that a uniform I spy on somebody's hand in that photo?

BTW, I don't do any of that anymore. I had a stroke in 2015, and have only one hand now. I can't even solder. I read somewhere there was an entry in /boot/config.txt to do with hdmi that affected sound, but I have a reliable system, and obey rule #1: "If it works, don't fix it!"

If I was going again, I'd probably get the Orange Pi 5, but I'd check for a video driver first.

Yah I know about those Radio Shack days too -- only 3D printing makes it 'much' easier now a days . Still had some soldering to do to get everything working in the 3D printed box! Design parts with FreeCad (what I use) and print.

That link to picture above is actually the 'real' prop used in the 1960s original Star Trek TV series. The hand is First Officer Spock's hand . I used that picture to design my own.

Got a picture of my enhanced Star Trek Computer. Even has two factor authentication to get in... The red block has to be first placed in the slot, then it will ask for an authentication code which you key in with the right four black buttons:

The original 1960s version? We never got to see Star Trek before the 1980s. Time wasn't good to that show.

Of course TV in Ireland was a bit of a joke back then. Our national TV opened in 1961 on a miniscule budget from 16:00 to 21:00 initially. It rapidly extended the evening but only added another channel in the late 1970s. We got repeats of every failed show, and aberrations of nationalistic and religious concepts the station was forced to broadcast.

What we got very good at was pinching British TV. They broadcast to Britain and Northern Ireland, but tried to avoid sending us in the South of Ireland any signal. People here took that as a challenge. Tall masts were set up, & expertise developed. You could buy Hirschmann aerials in every electrical wholesaler in the country, along with a selection of amplifiers. Hirschmann built these aerials with 13dB of gain which were aimed like a telescopic sight at transmitters in the NOI, Wales or England. It's all gone digital now, of course.

There is one funny story I'll pass on. When ordering my replacement hip, the surgeon specified a Tritanium him socket. I looked up tritanium on the web. There was absolutely nothing on it, except for a wikipedia entry. Tritanium, according to Wkikpedia, was one of those joke metals used in star trek technobabble .

Tritanium is also a plastic with excellent qualities. Both my hips have been done. One has a screw holding in a normal (cheap) hip socket. The other has the Tritanium socket, and no screw was needed. The pain was much less.

Well, I didn't see the episodes either as I was to young and we didn't (and still don't) have a TV... But I did read the books (and still have) the Star Trek series 1 to 10, and then the logs 1 to 10 (I think these came from the cartoon series) that fired my imagination. Also some the episodes are on the web if any one ever wanted to see what it was about.

Sorry to here about your health issues.

Oh, here is another computer with a RPI4 behind it. A 1/3 scale PDP 11/70 front panel. Fun to dink with as you can load a lot of old OSs for fun. All the switches are 'active' just like on the real computer. Pretty neat. I use it for more than a simulator too as the simulator only takes a fraction of the RPI4 CPU usage.

I had no particular interest in Star Trek. But I would watch it with my kids, and they liked and would call me for it. And we saw all the films worth seeing in the 1990s - the back to the future trilogy, star wars, Ghostbusters 1 & 2, etc. Happy days.

I was in a company with a PDP-11 for a while, but it was an R&D place where the manager kept adding capital requirements to his budget requests. So it ended up there doing little or nothing, and any of the engineers could play with it. That was just before the PC came out.

The way I have my Pi 4, my ssd is in the lowest priority usb-3.x socket. I have a 3rd /home partition. I can trump it with LibreElec by using an sdcard or usb key. LibreElac (based on Debian)has the proprietary driver, so I can get videos.

This actually booted and ran on my single core 700hz 512MB ram raspberry pi. I installed it on sd card from another computer though using Belena Etcher. Use a hard line for internet.

Firefox did like 512MB of ram though. So run Dillo2. I figured a way to watch online videos using mpv.

Because my board is older. It runs a bit slow.
