Dotnet octo pack fails

[stefanm.nilsson]

Hi,

After upgrading .NET Core from 2.1 to 3.1, we get the following error during deployment:

+ PATH=/root/.dotnet/tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games dotnet octo pack --id=Company.Api --version=0.6.0.68 --basePath=./Company.Api/dist

It was not possible to find any compatible framework version

The framework ‘Microsoft.NETCore.App’, version ‘2.1.0’ was not found.

• • The following frameworks were found:*

•  3.1.1 at [/usr/share/dotnet/shared/Microsoft.NETCore.App]*
  

You can resolve the problem by installing the specified framework and/or SDK.

We tried upgrading from “Octopus.Tentacle.4.0.1” to “Octopus.2019.13.0-x64”, but the error remains.

Any Ideas?

Regards

Stefan

Hi Stefan,

Thanks for getting in touch.

Octo is installed independently of Tentacle, so upgrading Tentacle will not have an effect. Octo can be installed either as a dotnet tool or by unzipping an archive. For the archive version there is no dependency on a specific version of the .NET core runtime but as a tool you must have .NET core SDK 2.1.x installed. (This is called out in our docs here: https://octopus.com/docs/octopus-rest-api/octo.exe-command-line/install-global-tool).

Your options would be to install the 2.1 SDK, or use the archive for your chosen OS which is available from our downloads page: https://octopus.com/downloads

I hope this helps.

Cheers,
Shane

Thanks,

I managed to solve this issue by installing .NET Core 2.1.0 and executing the docker step with a reference to this version.

Hi Stefan,

Just following up on this one. We are currently working to distribute Octo as a self-contained executable, which will remove the requirement to have .NET core installed. You can follow progress here: https://github.com/OctopusDeploy/Issues/issues/6128
