All storage servers were migrated to Ubuntu 20.04 in November 2022. This has little effect on users since most storage servers have little user-relevant software installed (but see below for any outstanding issues).
Migration of POD compute servers to 20.04 began in with the December 20 maintenance window. The current schedule is shown below but is subject to change.
- December 20, 2022 - Chen/Wallingford and EDU; maybe CBRS
- January 3, 2023 - Dickinson/Cambronne, TBD
Find your OS version
To determine which OS version a server is running, do the following in a Terminl (including RStudio Server or JupyterHub Server Terminal): lsb_release -a. On the Release: line you should see either 20.04 or 18.04.
Known outstanding issues
- JupyterHub Server
- Clicking "Logout" in JupyterHub server does not work – it displays a "404 page not found" error.
- Command-line programs
- The bcl2fastq program is not installing correctly so does not work.
- On the EDU pod, the 3rd party programs used by Josh Beckham's FRI stream (e.g. Gold) are not yet working.
- Storage server access
- The rssh program that allows direct access to the shared storage server via SSH (e.g. scp, rsync, sftp) is not available in Ubuntu 20.04. We are actively working to implement a suitable replacement. Meanwhile, files can be transferred to/from the storage server through any of a POD's compute server via scp, rsync, sftp.
