Wrong Digest errors using Packman repo

Trying to clean up my system having removed some factory repos so now I have the standard 4, update, oss, non-oss & packman.
When updating and switchine to packman I get many Wrong Digest errors and when downloading many NO KEY messages.

What is the significance of the no key message. How can I renew keys from repo sites and what should I do about the Wrong Digest warnings?

This problem was already discussed in →this thread - actually it should be solved meanwhile. Which Packman mirror do you use?

Hi and thanks for the link. I am using inode and have just tried an update once more. This time it ran with many files updated and no errors.
Thanks again,
