Ubuntu 16.04 node complains about DEB Repository Signature (Puppet Enterprise 2016.2 )
Our Ubuntu 16.04 are managed by Puppet Enterprise 2016.2. While running an apt-get/aptitude ... (e.g. update) they compain about a weak Signature and a missing Date filed in the lists file.
W: https://puppetmaster:8140/packages/2016.2.0/ubuntu-16.04-amd64/./Release.gpg: Signature by key 47B320EB4C7C375AA9DAE1A01054B7A24BD6EC30 uses weak digest algorithm (SHA1) W: Invalid 'Date' entry in Release file /var/lib/apt/lists/puppetmaster:8140_packages_2016.2.0_ubuntu-16.04-amd64_._Release
Is there a way to fix this?
