@wfurt

@wfurt if we have not started adding the RID, we should target to get those in as soon as possible for the April Release

@rbhanda

ok. I'll take look @rbhanda.

@rbhanda

@rbhanda - What is the status of this? If there are pending product changes that have not gone into April servicing, we will not be able to claim support on release day.

@dcwhittaker

We have already pushed last two updates to Ubuntu 22.04. We are ready to announce the added distro as supported with the April release. @dcwhittaker FYI for the April blog post

@mthalman

Thanks for the update. There is the one unresolved Arm32 issue @mthalman found which is linked here. It's something to consider noting in any announcements.

The arm32 issue is being fixed by dotnet/runtime#67145 for .NET 6.0, porting to older releases is going to be problematic and people are leaning against doing so.

.NET 5 is near EOL - will go out of support 17 days after Ubuntu 22.04 release, will there be another .NET 5 release before that?
.NET Core 3.1 does not officially support OpenSSL 3.0 and porting the fix would require large changes.

If you have any concerns, feel free to raise them in dotnet/runtime#66310.

@mthalman

There is the one unresolved Arm32 issue @mthalman found which is linked here. It's something to consider noting in any announcements.

@rbhanda, @dcwhittaker note that in the current state (i.e. without the fix in dotnet/runtime#67145), .NET is pretty much unusable on arm32 Ubuntu 22.04 (or any 32-bit platform with OpenSSL 3.0), as even the build commands like dotnet restore which download files over HTTPS will not work, just something to keep in mind for the blog post.

Any word on when the dotnet-sdk snap will be fixed?

echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list

sudo apt-get update
sudo apt-get install libssl1.1

If your error is continue, this is working. You can try it.

We haven't fixed the snap yet.

While we're discussing it, is the advantage of snaps that you don't have to register the Microsoft feed or something else?

I don't use snaps myself, but my understanding is that the advantages are (1) sandboxed dependencies and (2) distribution-agnostic installation on any distro with snapd installed, not just Ubuntu.

I'm guessing that value prop 2 is the big one. Thanks for the reminder.

for others looking for a solution:

The impish repo didn't work for me, but this did.

wft?! this is a supported framework or just steaming pile of sh*t?? 3.1 not yet 3 years old and it's uninstallable...

We got a lot of problems related to this issue (I believe). See dotnet/runtime#76199
Do we have a workable solution for it?

3.1 not yet 3 years old and it's uninstallable...

3.1 LTS is EOL in less than three months. So, it is understandable why there is no effort to make 3.1 run on Ubuntu 22.04. Length of .NET Core long time support is a separate issue.

After install dotnet-sdk-6.0 successfully (using the microsoft package feed) I could not install the dotnet-sdk-3.1.
There is a problem with the 'targeting-pack' dependency:

$ cat /etc/issue
Ubuntu 22.04.1 LTS

$ dotnet --list-sdks
6.0.401 [/usr/share/dotnet/sdk]
 
$ sudo apt install dotnet-sdk-3.1

Building dependency tree... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dotnet-sdk-3.1 : Depends: dotnet-targeting-pack-3.1 (>= 3.1.0) but it is not installable
                  Depends: aspnetcore-targeting-pack-3.1 (>= 3.1.10) but it is not installable
E: Unable to correct problems, you have held broken packages.

@viliamjr

@viliamjr .NET 6+ is supported on Ubuntu 22.04 - https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

@rbhanda

@rbhanda, can this issue be closed?

Thanks for the fix! Working perfectly again now! Cheers, Rudi
