Hi,
i tried to use the apt.puppetlabs.com repo on xenial. Since there are not package for xenial yet i tried to use the package from Ubuntu wily instead, but i ran into this error:
W: Failed to fetch http://apt.puppetlabs.com/dists/wily/Release No Hash entry in Release file /var/lib/apt/lists/partial/apt.puppetlabs.com_dists_wily_Release, which is considered strong enough for security purposes
I check the Release file and found the hash entries are wrong. apt (version 1.2.4) looks for the Hash entries "SHA512", "SHA256", "SHA1", "MD5Sum" or "Checksum-FileSize", but the file in the repository provides "MD5Sum", "SHA1Sum", "SHA256Sum". I think is a some kind of spelling mistake. The section "SHA256Sum" should be "SHA256" without the "Sum" suffix (same for SHA1).
I don't know what kind of changes are required to fix this, but i hope this can be fixed easily.
