Due to a recently discovered vulnerability in ThinLinc, all user sessions have been terminated and ThinLinc login disabled for now.

Right now we have some unknown problem with the file system for home directories and projects.

We're investigating and will try to solve things as fast as possible.

On Wednesday 2026-03-18 we will start an online upgrade of the storage system that contains users home directories and all project storage directories under /proj/nobackup.

/proj/cfl_nobackup will NOT be affected.

The upgrade will temporarily cause reduced performance and delays when accessing the file system.

To minimize problems with batch jobs the queues will from time to time be stopped from starting new jobs, but submitting new jobs will still work.

We will try to keep the impact to a minimum.

We are upgrading Kebnekaise compute and login nodes to Ubuntu Noble.

This will result in some older softwares to not be available anymore. We've tried to build everything that is currently used but when that isn't possible there should be newer versions available instead.

If something is missing despite our efforts, please send a support case through the SUPR support case interface (or mail support@hpc2n.umu.se) and let us know.

The ThinLinc access to kebnekaise-tl.hpc2n.umu.se is now working again.

The login node behind it has been upgraded to Ubuntu Noble (24.04)
