The autopkgtest started failing on ppc64el: Temporary failure resolving 'ftpmaster.internal'

[Iain Lane]

If you look at the history on

  https://autopkgtest.ubuntu.com/packages/n/netplan.io/hirsute/ppc64el

The autopkgtest started failing on 2021-02-12 with

Err:1 http://ftpmaster.internal/ubuntu hirsute/universe ppc64el wireguard-tools ppc64el 1.0.20200827-1ubuntu1
  Temporary failure resolving 'ftpmaster.internal'
E: Failed to fetch http://ftpmaster.internal/ubuntu/pool/universe/w/wireguard/wireguard-tools_1.0.20200827-1ubuntu1_ppc64el.deb Temporary failure resolving 'ftpmaster.internal'
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

when trying to run the 'tunnels' test.

There are a couple of passes of 0.101-4ubuntu1 so maybe something else changed in the meantime to break this.

Hopefully this is reproducible in Canonistack, with:

  autopkgtest --shell-fail --timeout-copy=6000 --setup-commands setup-testbed --apt-upgrade netplan.io -- ssh -s ssh-setup/nova -- --flavor m1.small --name netplan --image ubuntu/ubuntu-hirsute-daily-ppc64el --keyname YOURKEYNAME

I'm adding a hint since this is blocking unrelated packages, but I think for things like netplan.io we need to fix the tests to have confidence they work on all supported arches.

Since this starts happening part way through, it might be that one of the earlier tests sabotages the system enough to break something with whatever new version of some dependency.

I've triggered the test with hello in Hirsute release pocket:
https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-hirsute/hirsute/ppc64el/n/netplan.io/20210225_023255_3a632@/log.gz

It looks as if wifi test broke the testbed.

Due to the nature of the tests it is fair to assume the any netplan.io test running as root can break the testbed and I suggest adding this restriction for them.

This bug was fixed in the package netplan.io - 0.101-4ubuntu3
