Weird bug, do you have an idea why it works as is on all my PRs?

[Half-Shot]

Not a clue :(. I'm about to give up and sudo it anyway, although it feels gross to rely on sudo.

@Half-Shot when you move olm libs gcc can't found it's headers. Perhaps you need to configure gss environment?

The problem appears to be on Travis side travis-ci/travis-ci#9875

Should this be squashed and merged now? I have no idea about best practices for installing dependencies on travis so can't really offer much help here.

[Zil0]

I don't think there are best practices when it comes to sudden undocumented change. This should probably be merged, while we wait on someone from Travis to comment in the above issue...

[non-Jedi]

Squashed and merged.

[non-Jedi]

I... merged this without a signoff. Oops.

[Half-Shot]

@non-Jedi I'm in the core team :)

Looks like this can be reverted now travis-ci/travis-ci#9875 (comment).
