[Bug 2062428] Re: Install randomly crashes/fails/hangs on systems with 3GB or less

[Chris Guiver]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. Please execute the following command only once, as it
will automatically gather debugging information, in a terminal:

apport-collect 2062428

When reporting bugs in the future please use apport by using 'ubuntu-
bug' and the name of the package affected. You can learn more about this
functionality at https://wiki.ubuntu.com/ReportingBugs.

No clues as to product are provided (three flavors use calamares, though
Kubuntu is used as example so it maybe Kubuntu but we don't know; is
this 24.04? as its not said though mentioned too), nor clues as to what
ISO was used, nor package version details. It's likely nothing can be
done without this detail; as package versions have changed multiple
times in the last few days & no useful data (no logs etc) were provided.
Please in future use `ubuntu-bug`... which can be run even from terminal
even during operation (or calamares-hang).

If your system has already gone (ie. I assume it was LIVE and thus after
failure you shutdown box), some detail can be added to the report if you
BOOT the same ISO on the SAME HARDWARE and run `apport-collect 2062428`
as requested there. This will populate most missing fields, even if no
calamares-log will be attached (you'd need to re-run the install & have
the same issue to get that).

As currently little detail is provided, I'll mark this bug as
incomplete.  If you do run `apport-collect`, please change the status
back to "New".   Thank you for filing the bug report in attempts to make
Ubuntu better.

** Changed in: calamares-settings-ubuntu (Ubuntu)
   Status: New => Incomplete

[Bug 2062428] Re: Install randomly crashes/fails/hangs on systems with 3GB or less

[Eugene San]

** Summary changed:

- Install randomely crashes/fails/hangs on systems with 3GB or less
+ Install randomly crashes/fails/hangs on systems with 3GB or less

** Description changed:

- Install randomely crashes/fails/hangs on systems with 3GB or less
+ Install randomly crashes/fails/hangs on systems with 3GB or less
  When the system doesn't hang, I can see kernel OOM killing random processes 
like calamares, cryptsetup etc.
  
  I had ~75% success of installing Kubuntu 24.04 daily on VMs with less then 
3GB and almost 0% on 2GB VMs.
  Previous livecd installers had no issues with 2GB VMs and
  
  Once the system is installed it functions satisfactory with 2GB.
  
  I believe adding zram-config to livefs/casper would allow installation
  on systems with only 2GB of RAM.
  
  Note,
  Similar issue also affects other Ubuntu images so the issue is not calamares 
specific.
  The problem first appeared around the time of switching to Kernel 6.8.
  I believe the issue is overlayfs related since that's the main difference 
between livefs and installed system and there were a lot of changes related to 
overlayfs.
