I've seen several other similar issues but their fixes didn't seem to work for me.
I looked at this issue but following these instructions didn't work

I have the same problem in a brand new Ubuntu 18.04.1 LTS (GNU/Linux 4.14.43-138 armv71) installation in a Odroid device.
If I run the apt search dotnet-sdk-2.1 command, it is able to locate the packages, but when trying to install them, I get the same error message.

@leecow any idea?

[leecow]

I have no idea. Do the other packages found with apt search act the same way?

[joseangelmt]

I tried with all of them and I got the same results. Then I searched for pngtools for example and it installed without any problem as you can see in the next gif:

Finally I decided to:

wget https://download.visualstudio.microsoft.com/download/pr/4d555219-1f04-47c6-90e5-8b3ff8989b9c/0798763e6e4b98a62846116f997d046e/dotnet-runtime-2.1.5-linux-arm.tar.gz
mkdir -p $HOME/dotnet && tar zxf dotnet-runtime-2.1.5-linux-arm.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnet

and it is working correctly because actually what I want was the runtime and not the sdk.

Closing this issue as we don't really have enough information to know why it is not working and the you seem to be unblocked.

Thanks, joseangelmt. Going about this the long way works. I installed dotnet-runtime 2.1.6. Just in case someone else wants to do this at some point, go to the dotnet downloads page.


If you want the x64 version, click ARM64. I'm not sure why they're switched but they are. Clicking one of these links will download the binary onto the "windows side" of your computer which you can just cd into.

and then just add the directory of the extracted tar.gz to your $PATH
