MachineLearningNotebooks: Unsupported Linux distribution

I am trying to download an AzureML dataset on Ubuntu 20.04. I am using azureml.core library. However, when I try to run it I get following error

  File "/home/bartek/.local/lib/python3.8/site-packages/dotnetcore2/", line 169, in attemp_get_deps

Are you planning to support 20.04 version of Ubuntu? Is there any roadmap? I found this issue from 6 months ago and would really appreciate to hear if anything had changed since then.

Right now I am using the workaround from here to make it work.

Warm regards

Issue solved

sudo apt install dotnet-runtime-2.1 The following packages have unmet dependencies: dotnet-runtime-deps-2.1 : Depends: libicu but it is not installable or libicu66 but it is not installable or libicu65 but it is not installable or libicu63 but it is not installable or libicu60 but it is not installable or libicu57 but it is not installable or libicu55 but it is not installable or libicu52 but it is not installable E: Unable to correct problems, you have held broken packages.

  1. Install libicu
    sudo dpkg -i libicu63_63.2-3_amd64.deb
  1. sudo apt install dotnet-runtime-2.1

Don’t know if there is a best way to do?

@Radeju We will now proceed to close this thread. If there are further questions regarding this matter, please respond here and @YutongTie-MSFT and we will gladly continue the discussion.

Hi! I’m planning to switch our pipeline from 18.04 to 20.04 soon as well. Looks like this may be a blocking issue. Do we have timeline regarding the fix?

Based on the log seems distro version is asserted by a whitelist. IMHO this is a bad design which can probably affect a lot of not-so-popular distros like arch or mint.

thanks for the feedback. We have recorded the feedback and added it as a feature request on our roadmap.
