问题
If i'm using the default travis file it looks like that the build machine is Ubuntu Precise.
Hit http://ppa.launchpad.net precise Release.gpg
Is there any tweak to use an trusty or utopic machine?
回答1:
This is now implemented, add to .travis.yml:
dist: trusty
to use ubuntu trusty.
回答2:
No. Only Precise. Works are ongoing re Trusty.
