Do you know what the failure is?

[kortschak]

I suspect it's a conflict between this and this.

The line that does have a sudo prefix probably shouldn't, but it can probably be fixed by adding sudo to the other line.

[vladimir-ch]

Removed sudo, pushed the commit, saw that the cache needs sudo to be removed, added sudo to the rm command, push-forced the amended commit, deleted sudo from the rm command, push-forced again, and ran go generate. But the checks pass now. PTAL

[kortschak]

Yeah, I thought you were being a little optimisitic just removing the sudo and leaving the cache artifacts with root ownership.

The sudo command is a bit like heroin, it solves all your problems, but then you keep needing to use it.

[kortschak]

For future reference, you can clear the cache via the travis UI (https://docs.travis-ci.com/user/caching/). This was necessary for master because its cache is independent of the PR caches. I've done that now and restarted the master builds.

[vladimir-ch]

That's good to know. I thought it was strange to control travis by pushing commits.
