*** This bug is a security vulnerability ***

Public security bug reported:

The package archives at ddebs.ubuntu.com are signed with signatures
based on SHA-1:

wget http://ddebs.ubuntu.com/dists/xenial/Release.gpg
gpg --list-packets < Release.gpg | grep digest
        digest algo 2, begin of digest 5e a9

Algorithm 2 is SHA-1: https://tools.ietf.org/html/rfc4880#section-9.4

The main archives use algo 10, which is SHA-512.

Please update the xenial and newer ddebs to use the newer signature
algorithm.

Thanks
