Bootstrapping / SLES15-SP4: An error has occurred during salt execution: unable to parse json.

[crefeldtc]

Hope, I'm right at this place.

Since upgrading to 2023.12 and adding the "product channels" SLES15-SP5, it is not possible to add new systems / salt clients by the Bootstrapping page. After approx. 15 sec. I receive a message "An error has occurred during salt execution: unable to parse json."

Today I upgraded to Uyuni 2024.01 and tried again - the result is the same.

The client is a newly installed SLES15-SP4 system and the Activation Key is referencing to SLES15-SP4-channels only.
ssh connection and credentials are fine and I see that some directories have been created at the client at /var/tmp/ .

Adding SLES15-SP5 clients isn't possible because there is no directory https:///pub/repositories/sle/15/5/ but for now this isn't the major problem.

The file /var/log/salt-ssh.log gets created and has a length 0.

The 3 repositories which were used during base installation are disabled.

Any idea where to look for more information? At least it would be helpful, if I could get a more meaningful error message.

Thanks in advance!
