Abaqus restart analysis delivers errors in Ubuntu 18.04 and 20.04

Hi all,

I have recently updated our servers to Ubuntu 18.04 (and also some to 20.04). But when running the Abqus restart job, it delivers the following error. This never happened in Ubuntu 16.04. I would appreciate it if anyone can help me to figure out the problem. I am using Abauqs 2020 HF5.
