We seem to be hitting https://github.com/chef/chef/issues/4863 on SLES 15 as well. It appears that changes were made to zypper.rb that now prevents upgrades. This seems to be a fundamental problem. Would anyone happen to know if there is a possible work around for this issue or if there exists a patch? We see that even the latest available chef client versions also exhinit the same problem”.
Can you please update on this issue. Thanks in advance.
