Hi,

I’m new to this forum and I’m not very expierenced in suma. We still build the suma environment in our company. During Tests an error appears while registering sles11 based clients via traditional bootstraping.

The error occures only when sle11 systems call the function “repo2solv” on the custom-repositorys. Deep debugging showed, that we need to change the hash from sha512 to sha256 - that works. But the problem still exists, when we add empty channels to the systems who are sle11 based.

In SLES12 all works fine … anyone have an idea?

Best Regards

sha512 is not supported on SLE11, sha256 is the best you can get on it. For the empty channel please check if metadata were generated at all (/var/cache/rhn/repodata// ).  
If metadata are available, please provide more info about the error you see.

It’s solved!! We changed the value sha256 to the softwarechannels and now all is fine with the caching.

Thank you mcalmer!
