non-prerelease test fails with '/root/.ros/X/rosout.log': No such file or directoryError opening rosout log

[130s]

Example sniekum/ar_track_alvar#116
Prerelease tests are passing.

Download file's storage location issue in sniekum/ar_track_alvar#116 is resolved thanks to @ipa-mdl's help.

But it still doesn't make sense to me why the error message in the title /root/.ros/X/rosout.log': No such file or directoryError opening rosout log happened and why did it get resolved at the same time, because the solution in the same ticket was about where to download the resource needed for the tests, and that has nothing to do with the location of rosout.log's location.

I won't, however, dig this deeper for now. Maybe those two locations are related somehow. We can reopen when this happens again.

Happening on another repo wg-perception/people#49
An example from Travis.

I don't see a connection, at least no hint on read-only system problems..

Yeah seems like.

I didn't mean to ask for the help @ipa-mdl -- I like to leave as much data as possible whenever I hit issues. But I always appreciate the company :)

It could have been a regression bug as well, so keep on pointing to problems :)

I am a little bit concerned that the log output is not as helpful as it should be..
