Hallo Johannes,

the issue you reported seems to be related to the following documented bug:

Article ID : BR10000291796 
Abstract :  Abaqus/Standard analyses enter an infinite loop if the job attempts to exit with an error on SLES 15 and Redhat 8 Linux systems.
Link :  https://kb.dsxclient.3ds.com/mashup-ui/page/document?q=docid:BR10000291796
"When running on SLES 15 and Redhat 8 Linux systems, Abaqus/Standard analyses enter an infinite loop if the job attempts to exit with an error on SLES 15 and Redhat 8 Linux systems. The infinite loop occurs during shutdown of the standard process execution. The post analysis cleanup processes are not executed.
abaqus -job test terminate does not terminate this job. The Linux kill command must be used to terminate the job.
More specifically, this issue occurs on any Linux system that contains glibc version 2.25 or later. "

This bug is fixed in the latest Abaqus 2020 HF5 (2020 FP.CFA.2038) release, which will be available for download until the end of this week. Until you can install this version, you may use the Abaqus 2018-HF16 or Abaqus 2019-HF10 (or later) releases, which also contain this bug fix. 

Please let us know, if the issue is not gone even in the mentioned Abaqus releases.

Best Regards

I downloaded Part_SIMULIA_EstPrd - SIMULIA Abaqus 2020 FP.CFA.2038 - Linux64 from https://software.3ds.com/ and installed Part_SIMULIA_EstPrd.Linux64/1/Software/SIMULIA_EstPrd.HF5.Linux64/1/StartTUI.sh as well as Part_SIMULIA_EstPrd.Linux64/1/Software/CAASIMULIA_EstPrd.HF5.Linux64/1/StartTUI.sh and now it works on Ubuntu 20.04 without singularity-container.

@willfurnass For Abaqus 2018 they published a HotFix 16, which should also solve the problem.
