If you remove this from GitVersionExe.csproj
<PropertyGroup Condition=" '$(PackAsTool)' != 'true'">
<TargetFrameworks>net472;$(TargetFrameworks);</TargetFrameworks>
</PropertyGroup>
<PropertyGroup Condition=" '$(PackAsTool)' == 'true' ">
<ToolCommandName>dotnet-gitversion</ToolCommandName>
<PackageId>GitVersion.Tool</PackageId>
<PackageDescription>Derives SemVer information from a repository following GitFlow or GitHubFlow. This is the .NET Core Global Tool allowing usage of GitVersion from command line.</PackageDescription>
</PropertyGroup>
<ItemGroup Condition="'$(TargetFramework)'=='net472'">
<PackageReference Include="JetBrains.Annotations" Version="$(PackageVersion_JetBrainsAnnotations)"></PackageReference>
<PackageReference Include="LibGit2Sharp.NativeBinaries" Version="$(PackageVersion_LibGit2Sharp_NativeBinaries)" />
</ItemGroup>
You can then simply go to src/GitVersionExe folder and run dotnet publish -c Release -r linux-x64 --framework netcoreapp3.0 /p:PublishSingleFile=true which will produce a single executable in bin/Release/netcoreapp3.0/ubuntu-x64/publish/ that you can then easily use.
The documentation at https://gitversion.readthedocs.io/en/latest/usage/command-line/ lead me down a long winding path of curse words and head aches and in the end it still didn't work. So I decided to just check out the code and see if I could simply build it from source and in a matter of minutes it worked...
This is of course after following these steps to get dotnet core sdk3:

This issue is closed and notes about eventually being able to just use .net core #1229 that issue then relates to this PR #1269 which is now merged.
