I've had the same issues as well ever since I updated my .NET SDK to the latest version. I'm on Pop!_OS 22.04 (based on Ubuntu 22.04).

hello folks, after I had updated, the issue appeared to me too. dotnet worked but when I tried to execute with build arg or other few except --verion it showed me the error. what helped me, open link provided by baronfel, and do two steps: 'Use .NET 6 Package via PMC' and 'Scenario 1: Use native Jammy packages after installing a previous .NET release from PMC'

apt purge with a reinstall does not fix the issue.

Edit: I am using the dotnet-sdk-6.0 package, version 6.0.400-1, from the official Microsoft Debian repository:

$ cat /etc/apt/sources.list.d/microsoft-prod.list 
deb [arch=amd64,arm64,armhf] https://packages.microsoft.com/ubuntu/22.04/prod jammy main

It was working fine until I updated yesterday. I think I was on 6.0.300 before.

I updated the document to make it clear when you are intended to use of the "scenarios".

richlander avatar Aug 13 '22 18:08 richlander

Thanks, Rich! I followed the instructions in "Mixed state scenario 1" and am back up and running. It's nice to be able to install the SDK without an extra sources entry now.

jroeber avatar Aug 13 '22 18:08 jroeber

For sure. I'm glad the instructions helped.

install the SDK without an extra sources

Indeed. This is the plan going forward.

richlander avatar Aug 13 '22 19:08 richlander

Why is there this sudden change of installation steps? Is this going to be the one used moving forward?

khteh avatar Aug 14 '22 00:08 khteh

I'm seeing this too

olfek avatar Aug 14 '22 11:08 olfek

I have a fix !

  1. Run sudo apt remove --purge --autoremove *dotnet*

  2. create or modify /etc/apt/preferences and add (you'll need sudo)

    Package: *net*
Pin: origin packages.microsoft.com
Pin-Priority: 1001

    Run man apt_preferences for more info about this config.

  3. Run sudo apt install dotnet-sdk-6.0

  4. Enjoy !

@pietervdheijden Did you need to quote the whole post? A reaction would have been enough :P

@olfek great! It works for me! Thanx!!!

Thanks @olfek. This works for me as well. :-)

How is this not a breaking change? A minor version update shouldn't nuke a previously functioning installation! This breaks local dev, but it probably breaks a bunch of CI pipelines etc.

EDIT: https://github.com/dotnet/sdk/issues/27129#issuecomment-1214358108 is the correct fix at the moment.

Following the steps here: https://github.com/dotnet/core/issues/7699 will leave you with an outdated SDK and stuck with an old dependency of libunwind which can prevent other software installation / cause dependency conflicts.

seanamos avatar Aug 29 '22 09:08 seanamos

This breaks my dev env on Linux machine. Rider just suddenly not working anymore. Although I fixed it temperarily by https://github.com/dotnet/sdk/issues/27129#issuecomment-1214358108 (Thanks!) It's a very bad issue.

jinweijie avatar Sep 11 '22 03:09 jinweijie

Fix worked for me on the second attempt. Rider also broke for me.

I encountered this problem after installing .net7 on ubuntu 22.04. I also needed the .net6 SDK and runtimes which were already installed, but after the .net7 installation, they did not show up.

.NET SDKs installed:
  7.0.101 [/usr/share/dotnet/sdk]

.NET runtimes installed:
  Microsoft.AspNetCore.App 7.0.1 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 7.0.1 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

a couple of uninstall/purge/clean/remove steps yielded the same result; thus, for a quick workaround, I basically moved .net6 related directories from /usr/lib/dotnet to /usr/share/dotnet, which the latter path is configured to work with dotnet cli.

after moving .net6 SDK and runtime folders under /usr/share/dotnet; they started to list, and no issues with build & run

.NET SDKs installed:
  6.0.404 [/usr/share/dotnet/sdk]
  7.0.101 [/usr/share/dotnet/sdk]

.NET runtimes installed:
  Microsoft.AspNetCore.App 6.0.11 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.AspNetCore.App 7.0.1 [/usr/share/dotnet/shared/Microsoft.AspNetCore.App]
  Microsoft.NETCore.App 6.0.11 [/usr/share/dotnet/shared/Microsoft.NETCore.App]
  Microsoft.NETCore.App 7.0.1 [/usr/share/dotnet/shared/Microsoft.NETCore.App]

can anybody pls tell me how to ''add'' something to /etc/preferences ???

cd /etc ls -> if preferences (not preferences.d) is available skip next step sudo touch preferences sudo gedit preferences paste fix and save

HossamElwahsh avatar Feb 16 '23 20:02 HossamElwahsh

Don't use /etc/apt/preferences. Create a new file in /etc/apt/preferences.d instead!

sudo nano /etc/apt/preferences.d/dotnet

With content:

Package: dotnet*
Pin: origin packages.microsoft.com
Pin-Priority: 1001

and

sudo nano /etc/apt/preferences.d/aspnet

With content:

Package: aspnet*
Pin: origin packages.microsoft.com
Pin-Priority: 1001

EDIT: Or more easy with heredoc:

sudo sh -c "cat > /etc/apt/preferences.d/dotnet <<'EOF'
Package: dotnet*
Pin: origin packages.microsoft.com
Pin-Priority: 1001
EOF"
sudo sh -c "cat > /etc/apt/preferences.d/aspnet <<'EOF'
Package: aspnet*
Pin: origin packages.microsoft.com
Pin-Priority: 1001
EOF"

@olfek tip of the hat for you sir, it worked 🎩👌

epomatti avatar Jun 11 '23 12:06 epomatti

Why don't you just fix this?

aradalvand avatar Jun 24 '23 14:06 aradalvand

It's not straightforward to fix.

For folks that don't register the Microsoft feeds, there is no problem. It is the mixing and matching of the Ubuntu and Microsoft feeds that cause issues and require special handling.

richlander avatar Jul 28 '23 23:07 richlander

the best solution for this problem and others that Ubuntu has with versions is to use ASDF which has support for dotnet among others.
