Some repositories fail to update: "Is no longer signed"

[christian79]

Hello,


I have a server in an internal network which uses a proxy to access some parts of the web. For now the updates worked just fine, but it stopped working for 3 repositories a few weeks ago. Since then I have not found a solution to this issue.


This is my command line:

$ sudo apt-get update

I already tried to add the keys manually but it does not work. Interestingly not only the third party repos fail but also the security repository from Ubuntu itself.
This machine is running Ubuntu 16.04.


Do you have any suggestions how to resolve this issue?

Testing http://dl.google.com/ is switching to https://www.google.com/chrome/
Trying the new url https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb is working

So now https is used with a new path

Thanks! That fixed at least the google repo. But the Ubuntu security repo is still failing.

The https was also the issue on the Jenkins repo. I did the steps as described here: http://pkg.jenkins-ci.org/debian/

i does not get issue with:

deb http://security.ubuntu.com/ubuntu xenial-security main restricted multiverse
deb http://security.ubuntu.com/ubuntu xenial-security universe

Strange... Maybe the internal IT department changed something on the firewall. I replaced it by

deb http://de.archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
#deb-src http://de.archive.ubuntu.com/ubuntu xenial-security main restricted universe multiverse
This works fine.

Thank you for your help!
