sudo apt install fails with: Unable to connect to


I have a action that does sudo apt install gnat gprbuild to install an Ada compiler.

Since a couple days ago it was working fine, but now apt reports a connection error (full logs below):

Err:4 bionic/universe amd64 gnat amd64 7ubuntu1
Unable to connect to

Is there something more I have to do? Is it a problem on GitHub Actions side?

Thanks for your help,

Sorry about the delay, but I’m seeing connections to that endpoint working successfully.  Seems like it may have been an intermittent networking issue or brief problem with that repository.  Are you still having trouble?

It was an intermittent problem indeed.
