Core: Please provide packages for Ubuntu 20.04

[murbanowicz]

Hi,
I am not sure this issue should be created here, but I hope it's the right place. If not, please move it to an appropriate place.

Could you please provide packages for Ubuntu 20.04?
Packages for 19.10 working to some degree, but e.g. I cannot get 3.1.2 update, I am stuck on 3.1.1 (not to say it's critical or so, but would be nice to upgrade).

[scalablecory]

@dagood @leecow

[leecow]

@murbanowicz, what are you seeing when trying to 3.1.2 from the 19.10 repo?

20.04 will not be officially released until 4/23 and we typically have the repo established and populated with the .NET Core release which immediately follows but I think we can have this set up for 20.04 release day.

@rbhanda - please work with the AzLinux folks to get 20.04 on-boarded to packages.microsoft.com.

/cc @nakarnam

@leecow

The following packages have unmet dependencies:
dotnet-runtime-deps-3.1 : Depends: libicu but it is not installable or
libicu63 but it is not installable or
libicu60 but it is not installable or
libicu57 but it is not installable or
libicu55 but it is not installable or
libicu52 but it is not installable
E: Unable to correct problems, you have held broken packages.

20.04 has libicu65. It would be nice to have preview packages earlier.

[phillip-haydon]

I tried to setup 20.04 too, basically /everything/ works, except .net core... :( was hoping to play around with .net core on Ubuntu 20.04 but I guess I'll need to wait until release day.

[dagood]

You have a few options in the meantime:

• Use the binary installer. ("Binaries" link in the table from https://dotnet.microsoft.com/download/dotnet-core.)
• Create your own "fake" package to resolve the dependency. Take a look into the equivs package to do this for Debian packages. You could make a fake libicu63 package, or you could fake the dotnet-runtime-deps-3.1 package entirely. (You would want to have libicu65 installed to satisfy the functional dependency as well as the fake package to satisfy our Deb package's dependency.)

[baskmau]

@dagood - thank you very much!!!

[markusschaber]

Just for information: Ubuntu 20.04 will be released April 23rd, and is the next LTS version, so it will be supported for 5 years.

[yokovaski]

Any news on this?

[leecow]

@NikolaMilosavljevic for an update

[NikolaMilosavljevic]

All PRs were completed a month ago. There are upcoming servicing releases for 2.1 and 3.1 and 5.0 preview.

5.0: https://github.com/dotnet/runtime/pull/34079
3.1: https://github.com/dotnet/core-setup/pull/9015
2.1: https://github.com/dotnet/core-setup/pull/9016

All these changes added support for libicu65 and libicu66.

Please provide this packages.

[phillip-haydon]

I used the 18.04 source on 20.04 with the help from this tweet:

https://twitter.com/sinclairinat0r/status/1237201767198273536

wget http://mirrors.edge.kernel.org/ubuntu/pool/main/i/icu/libicu63_63.2-2_amd64.deb
sudo dpkg -i libicu63_63.2-2_amd64.deb

Then installed .NET Core normally.

[abhisheksubbu]

phillip-haydon approach worked perfectly in Ubuntu 20.04

[DenSmoke]

My ASP.NET Core 3.1 apps use 100% CPU on Ubuntu 20.04 when first network action occurs.

[vinceshere]

Still receiving an error, even after follow the new instructions page: https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-manager-ubuntu-2004

Ubuntu 20.04 LTS

The step bellow works normally:
wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb sudo dpkg -i packages-microsoft-prod.deb

This command returns the error message:
sudo apt-get install dotnet-sdk-3.1

Error: Unable to locate package dotnet-sdk-3.1

[DimitriPapadopoulos]

Please also update the release notes, add support for Ubuntu 20.04:
https://github.com/dotnet/core/blob/master/release-notes/3.1/3.1-supported-os.md

[dagood]

No .NET packages have been published to the Ubuntu 20.04 Microsoft repository yet, let alone packages that support 20.04. 😕 For now, you'll need to keep using the an earlier repository (18.04 for last LTS, or 19.10) with one of the workarounds above: installing the old libicu dependency manually, faking the libicu dependency to force the newer one to work, or using an alternative install method.

@Thraka, should we take down https://docs.microsoft.com/en-us/dotnet/core/install/linux-package-manager-ubuntu-2004? It looks like it was published prematurely. Alternatively we could decide on a workaround to document as official.

@leecow @rbhanda how is this distro version cycle being tracked? (How did this happen?)

[kpm]

I tried the 19.10 instructions as a workaround but I get "some packages could not be installed" due to unmet dependencies on other dotnet packages.

Just ran into the same trap and followed the docs. Resulted in me doubting my system. I think the docs as they are right now are very confusing or at least deserve a NOTE on them with a slight preference towards a note with a link to this issue.

[Fredrik81]

Just release it already :-D

[DenSmoke]

I am agree with @Fredrik81. Such a shame that MS couldn't release packages for Ubuntu 20.04 which is LTS version

[AlexandreDonovan]

I used the 18.04 source on 20.04 with the help from this tweet:

https://twitter.com/sinclairinat0r/status/1237201767198273536

Then installed .NET Core normally.

Worked for me thanks !

[SixOThree]

AlexandreDonovan's two lines worked for me.

[BrianXS]

the AlexandreDonovan answer didn't work for me what I did was:

• downloading the x64 package (be careful there are two x64, one for alpine linux an another generic, we want the generic one), and decompressed it at $HOME/dotnet

mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-3.1.201-linux-x64.tar.gz -C $HOME/dotnet

• and added the following lines to the .bashrc file at $HOME

export PATH=$PATH:$HOME/dotnet
export DOTNET_ROOT=$HOME/dotnet

• restarted the terminal, and it worked.

The toolchain for Ubuntu 20.10 _Groovy Gorilla_ will be ready this week. So when you add it to your CI directly, maybe it will be on time for the next release :wink:

[togabrennan]

@rbhanda any ETA on this? The instructions were up on the docs and then taken down again. Getting frustrated that this is still an issue on May 2.

[danipoma]

Just to extend on post from @BrianXS on how to install binary of .NET Core, which is already on Microsoft website.

mkdir -p $HOME/dotnet && tar zxf dotnet-sdk-3.1.201-linux-x64.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnet
export DOTNET_ROOT=$HOME/dotnet

This way dotnet tool works well on linux when you are using it in terminal, however when you try to use it in vscode (C# extension), then in debug/run step comes an error.

The terminal shell path "dotnet" is a directory

I am not going to delve into it too much into it, but adding dot before directory name does seem to fix that issue.

mkdir -p $HOME/.dotnet && tar zxf dotnet-sdk-3.1.201-linux-x64.tar.gz -C $HOME/.dotnet
export PATH=$PATH:$HOME/.dotnet
export DOTNET_ROOT=$HOME/.dotnet

Also there could be some improvements on what to copy/paste into terminal like cd into Downloads folder etc.

cd $(xdg-user-dir DOWNLOAD) && mkdir -p $HOME/.dotnet && tar zxf dotnet-sdk-3.1.201-linux-x64.tar.gz -C $HOME/.dotnet; cd
printf 'export PATH=$PATH:$HOME/.dotnet\nexport DOTNET_ROOT=$HOME/.dotnet\n' >> .bashrc

As a workaround, you can use the Eoan repository to get the missing package libicu-63.

sudo apt-add-repository 'deb http://archive.ubuntu.com/ubuntu/ eoan main restricted'
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1

[leecow]

Hey folks, 20.04 packages are expected to be available 5/12.

[phillip-haydon]

Hmmm really dropped the ball for support on this. There has been plenty of time to ready support for .net core on 20.04 but didn’t action it until well after the release.

[byroniac]

$ sudo snap install dotnet-sdk --channel=3.1.2
$ sudo snap alias dotnet-sdk.dotnet dotnet

The alias didn't work for with C# in the snap versions of VS Code and VS Code Insiders, so I wound up making a symbolic link in /usr/local/bin directly to the dotnet executable. Surprised that worked, but glad. See my comment here.

[maxdelemos]

$ sudo snap install dotnet-sdk --channel=3.1.2
$ sudo snap alias dotnet-sdk.dotnet dotnet

Thank you for this.

[philippun1]

snap version does not work either on Ubuntu 20.04. To reproduce just create a new dotnet core console app with:

dotnet new console
dotnet build
dotnet run

It will fail with:

Please see my comment here because you can set the environment variable DOTNET_SYSTEM_GLOBALIZATION_INVARIANT as a tempory workaround.

[iHackFX]

Temporary solution for me:

1. Download - https://dot.net/v1/dotnet-install.sh
2. Run in terminal:
   bash ./dotnet-install.sh --channel 3.1 --install-dir ~/cli
sudo mkdir /usr/share/dotnet
sudo mv ~/cli/* /usr/share/dotnet/

Installing via these steps worked great for me:

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1

However, I first had to run the following. I guess I needed to clean up previous attempts.

sudo dpkg --purge packages-microsoft-prod && sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update

[superbonaci]

@merschformann isn't there any repository so dependencies are met automatically?

@merschformann isn't there any repository so dependencies are met automatically?

If you look at the comment right above yours, I did the same thing, and it provides a repository, at least for Ubuntu (I can't speak for other distros as I have not tried anything else, but I know that Fedora 32 has them built in, for which I am very grateful to Microsoft and IBM/RedHat).

@mikevanl Please open a new issue with what you've tried and all command output, especially apt update. It's closed because the repository and packages are available for Ubuntu 20.04. But it can be tricky to set up the repository correctly and we'd be happy to help.

Try to add ":amd64" to the end of dotnet's package names.
Like this:
sudo apt install dotnet-sdk-3.1:amd64

I used this method and worked for me.

wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo add-apt-repository universe
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1 (chose the version)

@yelsnitrk you need to follow these instructions:

Package manager installs are only supported on the x64 architecture. Other architectures, such as ARM, must manually install the .NET Core SDK or .NET Core Runtime. For more information, see the manually install section below.

Thanks. I downloaded the binary that I want to my /home/user directory. What next?

[dagood]

@yelsnitrk you should be able to get it to work by continuing along with the instructions. Please feel free to open a new issue if some of the steps don't make sense or aren't working for you.

When I run the following i get the error that the dotnet-sdk-3.1 package is not found. Am I doing something wrong? Running pop_os 20.04 (based on ubuntu 20.04)

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-3.1

gives the error

1. add repository - https://docs.microsoft.com/en-us/windows-server/administration/linux-package-repository-for-microsoft-software
2. sudo apt-get install -y dotnet-sdk-3.1
   and you are done :+1:

I am in a similar situation, running dotnet-sdk 5.0.0-rc1 on Ubuntu 20.10 dev release which packages libicu67. Ubuntu 20.10 is going to be released next month so it didn't seem that crazy.

I modified the installer script for all the issues I ran into and stuck it here: https://github.com/averyfreeman/dotnet-sdk-5.0rc1-Ubuntu-20.10-installer

This worked for me - Brilliant. Thanks.
