etagecom.io repsitories signed with sha1

[matt9j]

Hello!
Starting in apt version 1.4 gpg certificates using sha1 as the digest algorithm have been disabled (see this blogpost https://juliank.wordpress.com/2016/03/14/dropping-sha-1-support-in-apt/). This impacts debian9 and ubuntu 16.04 or later. It looks like the repository maintainers need to re-generate the repository signing keys using a modern digest algorithm (https://unix.stackexchange.com/questions/387053/debian-9-apt-and-gpg-error-inrelease-the-following-signatures-were-inva). I originally found this issue working to deploy a community cellular manager osomocom client onto a debian9 machine. Let me know if there is any more info I can provide.
Cheers,
-Matt J.

Doesn't @kheimerl have access to the endaga.com repo? I think he and @shaddi are the repo maintainers.

[kheimerl]

Yes I can update the endaga one, not the etage one.
