Please link to the build in question. Copypasting things gives incomplete information.

Oh sorry, I didn’t know I could do that.

dotnet-sdk-3.0 is not available for Trusty (presumably because it’s EOL): https://packages.microsoft.com/ubuntu/14.04/prod/dists/trusty/main/binary-amd64/Packages

Move to dist: xenial (which is the default so you can just omit it) or dist: bionic.

Thanks!

It’s installing .Net Core 3.0 but it seems to fail when running dotnet build and I’m not sure why.

Perhaps because it cannot find your project files since they are in a subdirectory. You also probably don’t need the custom build script.

See https://docs.travis-ci.com/user/languages/csharp/.

You’re right, I didn’t even think about that

It started happening again. This is the build: https://travis-ci.com/github/applitools/Eyes.Sdk.DotNet/builds/172820224
