CryoSPARC Update for Ubuntu 26.04 LTS?

Install, Configure and Update

Dear CryoSPARC developers,

I’m currently in the process of replacing Rocky 8 by Ubuntu 26.04 LTS on all our Linux computers. To my surprise, I saw your recent warning “As of June 2026, CryoSPARC versions up to 5.0.6 are incompatible with the version 7 kernel that is the default for Ubuntu 26.04.” on your operating system requirement site. Indeed, on the first compute node with Ubuntu 26.04 LTS, a 2D classification job in CryoSPARC version 5.0.6 died with “Job is unresponsive - no heartbeat received in 180 seconds”. These are bad news for me.

Can you estimate, how soon a CryoSPARC update will be released, that will be compatible with the 7.x kernel in Ubuntu 26.04 LTS or any other new Linux distribution?

Best regards,

Dirk

We do not yet have a timeline yet as we are unsure of the root cause. Our investigation is in progress.

Do you specifically require a v7 kernel, or would Rocky-10 be a feasible alternative?

Thank you for your answer. So, I have to wait.

We decided to modernize our Linux installations and do the switch from RHEL clones, like Rocky, to Ubuntu LTS or Debian stable. On one of our servers, I will test the current Debian stable “Trixie” which comes with the 6.12 LTS kernel. However, since kernel “7” was an arbitrary naming decision by Linus Torvalds, it’s also not clear to me with which 6.x kernel version CryoSPARC starts having problems.

Best regards,

Dirk
