dnu and dnx commands fail silently with DNX Core on Travis / Linux builds

[dougbu]

This failure blocks fixing aspnet/Universe#290.

See https://travis-ci.org/aspnet/dnx/jobs/85979374 for an example.

info:   commandline: bash -c "source \"/home/travis/build/aspnet/dnx/packages/KoreBuild/build/dnvm.sh\" && dnvm use default -runtime coreclr && dnu --verbose restore --parallel src test samples"

Note the dnvm use writes its usual successful output at line 1078. The immediately-following dnu --verbose restore command outputs nothing but apparently has exit code 0 (doesn't fail the build).

Ran this test with a branch (dougbu/dnxcore.restore.290) of current dev to run dnu restore with DNX Core and to add debugging output. Any expected failures now that all release fixes are in dev?

The same branch builds fine on Ubuntu 14.04 and Mint 17.02 (a Ubuntu 14.04 derivative). Can't report on Mac until Travis restarts those servers. Anyone have a Ubuntu 12.04 system to debug further?

One suitable workaround would be to use Ubuntu 14.04 machines on Travis. Is that possible?

This problem is more general. Look for example at the end of recent dev build https://travis-ci.org/aspnet/dnx/jobs/85845411. Not sure what dnx commands do anything but return a 0 exit code when using DNX Core on Ubuntu 12.04.

This bug is a combination of #2875, an incomplete .travis.yml file in the DNX repo and an apparent incompatibility with Ubuntu 12.04. With a more complete Travis configuration, Linux builds still fail but somewhat more noisily. Got OSX builds working with DNX Core doing the dnu restore however.

fail: Exit code 1 from /usr/bin/env

Either dnu restore can't work with DNX Core on Ubuntu 12.04 or dougbu/dnxcore.restore.290 is still missing a dependency. See Travis build 4885.1 for example. Unfortunately my attempted build with the experimental Ubuntu 14.04 image (4886.1) failed while attempting to install Mono.

FYI we don't get any additional output without --quiet or with --verbose

Hi, I tried to install ASP.NET 5 On Linux just now on a Ubuntu 15.10 setup. I also get silent fails.

I don't get any output at all when I run dnu --verbose restore in a ASP sample project.

[dougbu]

@Scorpiion you need to install the libicu-dev package for .NET Core to work correctly on Linux. Unfortunately .NET Core is not compatible with the ICU version normally provided for Ubuntu 15.10: You need ICU v5.2. If you get that installed and visible to .NET Core, you're entering uncharted territory because only exactly Ubuntu 14.04 is a supported platform at the moment.

FYI there have been a few discussions around getting things going on Ubuntu 15.10. May be more information elsewhere in the various aspnet or dotnet issues lists.

(Thanks for the reminder. This bug should be closed.)

[Scorpiion]

Okay, thanks for the quick reply @dougbu, appreciate it. I got some samples running with the mono version at least.

Looking forward to try out .NET Core more in the future. 👍

@Scorpiion See #3059

Thanks for the link @moozzyk. 👍

On 14.04 LTS I get the same error. Looking at the ouptut when export DNX_TRACE=1, I get:
