CI for mrbayes

[Nadiya Sitdykova <rovenskasa@gmail.com>]

Hello Andreas, 

I finished and pushed test-suite for mrbayes package, but autopkgtest in chroot fails with errors:

E: Failed to fetch http://cdn-fastly.deb.debian.org/debian/pool/main/g/gcc-6/libgfortran3_6.3.0-21_amd64.deb  404  Not Found [IP: 151.101.52.204 80]

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

autopkgtest [23:34:59]: ERROR: testbed failure: apt repeatedly failed to download packages

I looked in this address and libgfortran with such name is really missing. Also I tried apt-get update and upgrade and it didn't help. Any ideas?

Regards, Nadiya
