This question already has an answer here:
This is not a duplicate, because previously such question was asked at July 27. The answer was "only several hours passed, you should just wait". Now this answer does not fit. The question is different when asked on August 6 than when it is asked on July 27.
It is August 6, 12:15 UTC time.
I try to upgrade from 16.04.5 to 18.04.1, with do-release-upgrade, and receive "No new release found."
They said that the upgrade will be ready "several days" after 18.04.1 release.
The release was in June 26. It is August 6 now. 11 days passed. Several days?
So the question is, is it only my problem? Or it is a bug in do-release-upgrade? Or they have a problem which they cannot solve yet, and I should just wait a bit more?
