Comment 5 for bug 1794059

I didn't want to retrigger your upload since I don't own it.

But I spun up three PPAs to check if this build time test is flaky.
The following three just started building:
- https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3431/+packages
- https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3432/+packages
- https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/3433/+packages

Result:
- 1 build
  - no errors at all
- 1 build
  - amd64 error (1) of above
  - i386 error (1) of above
- 1 build
  - i386 error (1) of above

So as you already found it really is a flaky test at build time.

I see for this time you already pushed "retry to win"
