5.1.0 Error on Azure Devops ubuntu Agents

[MattMencel]

I just noticed my builds on AzDO have started failing with the new 5.1.0 release. I've tried with the Ubuntu 16.04 and 18.04 agents.

- script: |
    dotnet tool install --global GitVersion.Tool
    ~/.dotnet/tools/dotnet-gitversion /output buildserver
  displayName: "GitVersion Setup and Run"

  ERROR [10/28/19 17:05:54:37] An unexpected error occurred:

can you try the hotfix version, 5.1.1?

[MattMencel]

Tried 5.1.1 and seems it's the same issue? For the moment I can stay on 5.0.1, but if you want more information just let me know.

@MattMencel, can you try the version 5.1.2-beta.1+4 and let me know if it fixed the error?

[arturcic]

@MattMencel any updates?

[MattMencel]

Hey @arturcic sorry about the delay... No errors! 👍 I used the latest 5.1.2-beta1.12.
