Lubuntu 22.04 LTS LiveCD consistent crash since Aug 2023

[lbunti]

Reproducing the issue is very simple.

1. Boot a LiveUSB drive with Lubuntu 22.04.3 LTS Jammy Jellyfish

2. Once it starts, do “cat /etc/apt/sources.lst” to see :
   deb cdrom:[Lubuntu 22.04.3 LTS Jammy Jellyfish - Release amd64 (20230807)]/ jammy main multiverse restricted universe
   deb Index of /ubuntu jammy main restricted universe multiverse
   deb h t t p security dot ubuntu dot com/ubuntu/ jammy-security main restricted universe multiverse
   deb h t t p security dot ubuntu dot /ubuntu/ jammy-updates main restricted universe multiverse

3. sudo apt update
   This shows some errors among other successful updates :

4. sudo apt install pychess

The GIU will crash and shows messages like :
integrity: Problem loading X.509 certificate -65
[FAILED] Failed to setup automunt Arbitrary Executable File Formats File System Automount Point.

[FAILED] Failed to start Snap Daemon
[FAILED] Failed to start Bluetooth service
[FAILED] Failed to start Avahi mDNS service

This happens with both Intel and AMD laptops I have tried (Intel is i5 with Intel graphics Dell Lattitude E5430 laptop and AMD is Ryzen 3 AMD Radeon Vega graphics Acer laptop).

I was using the same steps with Lubuntu 22.04 the same steps were working just fine for a year now and this issue started to happen from August 2023. So I tried the newer Lubuntu 22.04.03 LTS and the same issue happens. So this is some issue with update process after August 2023.

Also once the crash happens I have not found any way to get back to the command line or GUI. Even short press on power button or ctrl-alt-F3 does not help and since this is running from liveCD USB there are no crash logs etc. left after hard reboot.

I have monitored cpu/mem just before crash and the metrics for cpu/mem are way below max in the laptops (less than 25% used of 16gb mem and 50% cpu).

Any help is most appreciated. Thanks.

E: Failed to fetch h t t p security dot ubuntu dot /ubuntu/pool/main/g/glibc/libc-dev-bin_2.35-0ubuntu3.1_amd64.deb 404 Not Found [IP: 185.125.190.39 80]

Your details are unclear to me sorry, and that message is a result of sudo apt update not being run I believe, as the package available is

libc6-dev | 2.35-0ubuntu3.4  | jammy-security  | amd64, arm64, armhf, i386, ppc64el, riscv64, s390x
libc6-dev | 2.35-0ubuntu3.4  | jammy-updates   | amd64, arm64, armhf, i386, ppc64el, riscv64, s390x

ie. 2.35-0ubuntu3.1_amd64.deb is coming from an outdated software list, and you need to run sudo apt update before your machine will notice 2.35-0ubuntu3.4 is the correct package

[FAILED] Failed to start Snap Daemon

is a message that is often seen when using optical media, which Ubuntu has not been specifically built for since Ubuntu 20.04 LTS, as flash media is now the expected media. Optical media (such as DVD media) is much slower, and timeout issues can occur, however the wording you used may indicate you’re already using flash media. You also mention a specific time period (August 2023) which to me may mean you’re hardware is having issues with the 6.2 kernel for example, thus a fix maybe using 22.04 with a GA kernel stack (ie. Linux 5.15 LTS kernel), but I’m unsure of your facts sorry (unclear to me).

so, on a live boot, you’re doing a full update and also installing software, on a live boot? Pretty much a sure way to tempt breaking something (that first update requires a reboot for all changes to take effect, kernel updates etc.) on anything linux (only exception I’ve come across in 10 years is Void, but that’s different, more like the BSD installer). If its working on a live boot, good practice is to install it without updating, restart when complete and prompted, then do an update, and then install stuff.
