I use Ubuntu 20.04 with KNIME forwarded by X. I tried KNIME-full (with all extension) and normal KNIME without any addidional extensions and currently no anti virus.
KNIME does not open its sample workflows: If I double click, the “Description” is shown but nothing else happens for minutes.
If I try to import my own simple workflows, it takes minutes to import it I then I kill unfinished KNIME.
If I try to create a new workflow, nothing happens after entering the workflow name.
The logile /knime-workspace/.metadata/knime/knime.log is empty.
