Broken system with Ubuntu 22.04 where Microsoft packages are partially replaced by Canonical packages

[Robinsond76]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

My issue seems to be similar to this one except I'm on linux (popOS 22.04).
Summing up the problem - when I attempted to use dotnet watch run today, I got the * You intended to execute a .NET SDK command: No .NET SDKs were found. message.

When I attempt to install the dotnet sdk using sudo apt install dotnet-sdk-6.0 I get dotnet-sdk-6.0 is already the newest version (6.0.400-1).

When I do dotnet --info, I get:

  Not found

Host:
  Version:      6.0.8
  Architecture: x64
  Commit:       55fb7ef977

.NET SDKs installed:
  No SDKs were found.

.NET runtimes installed:
  Microsoft.AspNetCore.App 6.0.8 [/usr/lib/dotnet/dotnet6-6.0.108/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 6.0.8 [/usr/lib/dotnet/dotnet6-6.0.108/shared/Microsoft.NETCore.App]

I've tried doing whereis dotnet and adding all those paths to my $PATH but it didn't solve my problem. It was working just fine yesterday. Today when I got on the computer, I ran system and vscode updates - I don't know if that caused the problem.

Here is my whereis dotnet:

usr/bin/dotnet /usr/lib/dotnet /etc/dotnet /usr/share/dotnet /usr/lib/dotnet/dotnet6-6.0.108/dotnet /usr/share/man/man1/dotnet.1.gz

Here is my path:

/home/robinson/.nvm/versions/node/v18.7.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/robinson/.dotnet/tools

I've also tried removing all dotnet packages that showed up in apt list installed 'dotnet*', restarting and reinstalling.

Any help is appreciated.

It should look for SDK next to the dotnet executable. So based on the output - your setup picks dotnet in /usr/lib/dotnet/dotnet6-6.0.108 and there is probably no SDK installed there. I don't know what would put it there (standard package installers should put it into /usr/share/dotnet.

I had exactly the same issue yesterday, following the same steps you did there. Eventually removed the packages again and used the dotnet-install.sh script to install it and that works (instructions can be found here: https://www.how2shout.com/linux/how-to-install-net-core-dotnet-on-ubuntu-22-04-lts/).

Hello everyone,
it seems people started having the same issue and someone posted some steps on how to solve it on my post on StackOverflow. Here is the link.

So I ended up solving the issue as well by doing the following:
I uninstalled everything I could that was dotnet related with: sudo apt remove 'dotnet*'
Then sudo apt update
Then I followed the instructions on this link to unpack the binaries straight into the /opt/ folder. Once I added the necessary lines to PATH (according to the instructions in the link), everything worked as expected.

I would however recommend following the instructions in the StackOverflow post first as using the package manager might be the better solution.
Thank you everyone.

I can't reproduce this issue. Fresh install of popOS 22.04, installing the distro dotnet-sdk-6.0 package, yields a found SDK in the correct place:

I'd like to add my experience today. Yeah, I've had the exact problem and solved removing dotnet and reinstalling using the "scripted install". No other installation process worked (all I tried, seems to install - quite quick - but no SDK)

sudo apt remove 'dotnet*' --purge
and I've followed the scripted install [https://docs.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#scripted-install]

After that, dotnet started to work.

Unfortunatelly, after turn off the computer and turn on again next day, SDK was out again.

Reseaching, I found this [ https://github.com/dotnet/sdk/issues/27129#issuecomment-1214358108 ] solution that worked perfectly. Don't know if it's the right solution, but makes sense.

This is a duplicate of dotnet/core#7699 - that's the canonical reference on how to deal with the problems in question.
