Hello,
I would like to upgrade stat1008 from buster to bullseye this Thursday at approximately 09:15 UTC.
The upgrade is expected to take up to an hour, during which time stat1008 will be unavailable for use. Work in your home directories will be left untouched, so the impact should be low, especially if you are using conda environments https://wikitech.wikimedia.org/wiki/Data_Engineering/Systems/Conda.
If this maintenance window is likely to cause an issue for you, please do let me know and I can look to reschedule the work. We will also be available after the upgrade, in case you experience difficulties with the upgraded operating system.
After the upgrade, stat1008 will have new SSH host fingerprints, so I will update this page SSH_Fingerprints/stat1008.eqiad.wmnet https://wikitech.wikimedia.org/wiki/Help:SSH_Fingerprints/stat1008.eqiad.wmnet and provide some more help to get you reconnected.
Kind regards, Ben
