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, please check dotnet/core#7699 for more details about this.

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.

richlander · 2022-08-13T18:35:38Z

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

dotnet/core#7699

jroeber · 2022-08-13T18:40:56Z

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.

richlander · 2022-08-13T19:05:30Z

For sure. I'm glad the instructions helped.

install the SDK without an extra sources

Indeed. This is the plan going forward.

khteh · 2022-08-14T00:41:04Z

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

olfek · 2022-08-14T11:18:29Z

I'm seeing this too

olfek · 2022-08-14T12:15:21Z

I have a fix !

Run sudo apt remove --purge --autoremove *dotnet*
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.
Run sudo apt install dotnet-sdk-6.0
Enjoy !

@olfek Great, this fix solved my issue. Thanks!

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

My bad... I updated the comment!

ferneyvanegas · 2022-08-19T21:21:29Z

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

Johnny-Tommy · 2022-08-22T16:19:36Z

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

seanamos · 2022-08-29T09:17:10Z

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:
#27129 (comment) is the correct fix at the moment.

Following the steps here: dotnet/core#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.

jinweijie · 2022-09-11T03:40:46Z

This breaks my dev env on Linux machine. Rider just suddenly not working anymore. Although I fixed it temperarily by #27129 (comment) (Thanks!) It's a very bad issue.

0xStuart · 2022-12-11T19:06:09Z

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

ozgend · 2022-12-29T14:15:51Z

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 ???

richlander · 2023-02-02T21:54:50Z

There is more detail here: dotnet/core#7699

HossamElwahsh · 2023-02-16T20:37:47Z

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

kitingChris · 2023-02-17T14:21:15Z

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"

pantcr7 · 2023-06-08T05:13:10Z

I have a fix !

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

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

aradalvand · 2023-06-24T14:59:29Z

Why don't you just fix this?

richlander · 2023-07-28T23:40:18Z

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.

TalesPalma · 2023-09-07T23:00:50Z

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

gleison1986CEO · 2024-02-15T21:05:18Z

Solution for ubuntu 22.04
#============================>

sudo apt remove dotnet* // REMOVE ALL INSTALATION DOTNET
sudo rm /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update && apt-get upgrade
sudo apt install -y dotnet6 && sudo apt install -y dotnet7 && sudo apt install -y dotnet8 && sudo apt install -y dotnet5 && sudo apt install -y dotnet3 && dotnet --list-sdks
#============================>

AND DONE!

"JESUS IS LORD FOREVER!!"
