.Net 8 not installable on Ubuntu 24.04

[PavelCibulka]

Hello, it is not possible to install .Net 8 on Ubuntu 24.04 due to Ubuntu having libicu74. (.Net 8 can use libicu up to version 0.72 - libicu72). Please add libicu74 as dependency alternative for libicu.

@leecow heads-up, we may have a packaging dependencies issue

Are you using our jammy feed on Noble?

I installed dotnet8 from the native feed and it works fine.

It was from 23.10. When I try 24.04 it says that package is not available:
sudo nano /etc/apt/sources.list.d/microsoft-prod.list
deb [arch=amd64,arm64,armhf signed-by=/usr/share/keyrings/microsoft-prod.gpg] https://packages.microsoft.com/ubuntu/24.04/prod noble main

sudo apt install dotnet-sdk-8.0

Package dotnet-sdk-8.0 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'dotnet-sdk-8.0' has no installation candidate

I'm seeing similar failures from Apt trying to fetch the sdk in our Packer builds as commented here

Seems it's only dotnet-sdk-8.0 that's having the issue for Ubuntu 22.04 for me

@PavelCibulka I was not able to repro this issue. I used a fresh Docker container with ubuntu:noble image.

The following steps were successful:

apt update
apt install dotnet-sdk-8.0
dotnet --info

Do you still get the same error? Can you share specifics about the machine environment where this was attempted, and full set of repro steps?

@chriscarpenter12 was this an intermittent issue in your machine environment? I am not able to reproduce it. If you are still experiencing this issue, can you share more specifics and steps to reproduce?

[chriscarpenter12]

@NikolaMilosavljevic It was intermittent but over a few days and through the weekend. Seems to be fine since late Monday. I haven’t had a build fail since. Thanks for following up

[NikolaMilosavljevic]

Closing as no-repro.

I've the same issue. In you example the dotnet is installed from archive.ubuntu.com/... repo, in the original example by @PavelCibulka packages.microsoft.com/ubuntu/24.04/prod reoo is used. And it still doesn't have any dotnet packages published.
Are there any reference date when the packages will be available?
