I’m told this message is also present in updates that install successfully, so I do not think it is related to the issue at hand (but I could be wrong)
Not sure where you heard that, but ideally you shouldn’t be seeing this message at all. Your logs look almost the exact same as the symlink issue I described. See this thread to compare: [aktualizr, offline updates] Found in archive a file with bad file type: 40960
Also I misremembered it was the customer in the thread I just linked that had a workaround for this issue.
But yeah, in the thread I just linked the customer there too had the same error message with the same file type number of “40960”, which should denote a file type of symlink. Our update client back in 5.7.0 can’t handle docker metadata if it contains a symlink file.
