Has anyone managed to install the latest SAP ECC6 EHP8 with ASE 16 database on SLES 15 for SAP SP1?

My install is stopping at the ABAP import, and it seems that the environment variables for the <sid>adm user are not being set. The scripts are there but do not seem to have correct permissions to execute. When I execute them manually, the environment variables are still not set. Setting them manually one by one seems to get the process one step further, but there are too many things missing so it just stops again.

Any ideas?
