Description

Observation

I did a manual installation on my RPi 3 without any issue. It looks like a setup issue on openQA.

openQA test in scenario sle-15-SP6-JeOS-for-RaspberryPi-aarch64-jeos-realhw-RPi@RPi3B fails in
prepare_firstboot

Test suite description

Run a test on real RPi hardware. To be used eg. with RPi4 machine.
Setup: https://confluence.suse.com/pages/viewpage.action?spaceKey=~dheidler&title=Hardware+Automation

Reproducible

Fails since (at least) Build 6.75 (current job)

Expected result

Last good: 6.74 (or more recent)

Suggestions

  • Look into what was found in #158404 which was about the last time this test failed ~1 month ago
  • This looks to be failing sporadically only? Try and reproduce it - take care to only run first_reboot to avoid reflashing the disk
  • Meanwhile the scenario is ok again but we want to improve. The call select_console('root-ssh') establishes an ssh connection within the os-autoinst backend and as visible in https://openqa.suse.de/tests/14266260/logfile?filename=autoinst-log.txt there is already retrying but seemingly only 5 times up to 1m, not longer. We should ensure that there are longer retries with exponential backoff up to let's say 30m
  • Add exponential retry in https://github.com/os-autoinst/os-autoinst/blob/master/backend/baseclass.pm#L1211
  • Consider using a higher value than 5 for the specific test scenario or machine related to RPi
