Release team:

• Notify .NET Core teams regarding new OS release
• Follow up with infra and add feed for new OS release to packages.microsoft.com
• Update release manifest files
• Create new Docker files to test the new OS
• Update the supported OS content on GitHub and marketing sites.

Document updates:

• Add OS prerequisites to the dependencies document
• Update distro install page

22.04 isn't expected to be released until April 2022.

[rbhanda]

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

[wfurt]

ok. I'll take look @rbhanda.

[MichaelSimons]

@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.

[rbhanda]

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

[MichaelSimons]

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.

[rzikm]

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.

@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.

[omajid]

Is installing OpenSSL 1.x an option on Ubuntu 22.04? .NET Core 3.1 (and newer) will work against that even on arm32, right? Could that be documented as a workaround?

Unfortunately, @omajid, we prioritize OpenSSL 3.0 when looking for a suitable library version, so the workaround would have to somehow make sure that dotnet does not see OpenSSL 3.0 libs, which is either very hard or impossible for common users.

Edit, actually, there is environment variable for that: CLR_OPENSSL_VERSION_OVERRIDE, which can be used to point dotnet to older OpenSSL version, so setting it to 1.1 could work. (see https://github.com/dotnet/runtime/blob/main/src/native/libs/System.Security.Cryptography.Native/opensslshim.c#L56-L77)

@rbhanda, @NikolaMilosavljevic - Can you investigate this (from #7038 (comment))?

It doesn't look like netstandard-targeting-pack-2.1 is getting published. It doesn't exist at https://packages.microsoft.com/ubuntu/22.04/prod/pool/main/n/netstandard-targeting-pack-2.1/.

Yes, the package is missing - @rbhanda @leecow can this be added for 22.04?

[NikolaMilosavljevic]

Installation on 22.04 will hit another issue, even after netstandard-targeting-pack-2.1 gets added to 22.04 feed.

dotnet-runtime-deps-6.0 package will fail to install due to missing libssl dependencies:

The following packages have unmet dependencies:
 dotnet-runtime-deps-6.0 : Depends: libssl1.0.0 but it is not installable or
                                    libssl1.0.2 but it is not installable or
                                    libssl1.1 but it is not installable

[bartonjs]

A 22.04 package should depend on libssl3: https://packages.ubuntu.com/jammy/libssl3

That's only true for .NET 6 and higher. .NET Core 3.1 doesn't try to load OpenSSL 3.

[leecow]

netstandard-targeting-pack-2.1 is now available at https://packages.microsoft.com/ubuntu/22.04/prod/pool/main/n/

[emmenlau]

@bartonjs I'm not sure I follow, why should that not apply to .NET 5? I fail to install .NET 5 for the exact same error, would be great if this could be fixed soon (Ubuntu jammy is just around the corner).

[mattiaswerner]

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

[tayfunuyar]

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.

[richlander]

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?

[Shadow53]

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.

[richlander]

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

[0xW1sKy]

for others looking for a solution:

The impish repo didn't work for me, but this did.
microsoft/live-share#4646 (comment)

[trendzetter]

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

[thangchung]

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

[slonopotamus]

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.

[viliamjr]

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

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

[MichaelSimons]

@rbhanda, can this issue be closed?

[rudi-cilibrasi]

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