Erlang 18.3 couldn't be pulled

Hello, the issue only appears in some repos, for other, it works fine. Logs:

18.3 is not installed. Downloading and installing pre-build binary.
Downloading archive: https://storage.googleapis.com/travis-ci-language-archives/erlang/binaries/ubuntu/16.04/x86_64/erlang-18.3-nonroot.tar.bz2
$ wget -o ${TRAVIS_HOME}/erlang.tar.bz2 ${archive_url}
The command "wget -o ${TRAVIS_HOME}/erlang.tar.bz2 ${archive_url}" failed and exited with 8 during .

Your build has been stopped.

It generally means that the combination of the Ubuntu release and Erlang version is not supported. For Trusty, the oldest version you can use is 19.0.

Should not it be deterministic? With same travis.yml file, build passes on fork repo but fails on the source. It is also worth noting that it worked before.

Success: https://travis-ci.org/amatalai/beam_inspect/builds/548329639/config
Failure: https://travis-ci.org/appunite/beam_inspect/builds/548332119/config

Oops. I meant “Xenial” in my previous post. Compare the builds, and you notice that the failing one (as shown in the logs) is using Xenial (16.04), which doesn’t have 18.3. We are moving the default to Xenial gradually.
