Install dotnet core on Linux Mint 19

Question

After following Microsoft tutorials on how to install dotnet core on linux mint 19 i got stuck to :

sudo apt-get install dotnet-sdk-2.1.4

I got prompted that it needs dotnet-runtime-2.0.5 to be installed and so i executed :

sudo apt-get install dotnet-runtime-2.0.5

And i got

The following packages have unmet dependencies:
   dotnet-runtime-2.0.5 : Depends: libicu55 but it is not installable

So the problem is that i cannot install this libicu55 because it doesn't exist. How can i fix this?

Solution 1

Microsoft has its own package source for ubuntu now. The official download page has detailed instructions: https://dotnet.microsoft.com/download/linux-package-manager/ubuntu19-04/sdk-current

The following deb package installs the package source in your system:

wget -q https://packages.microsoft.com/config/ubuntu/19.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb

After an sudo apt-get update you can simply install your favorite SDK (e.g. 3.0) via

sudo apt-get install dotnet-sdk-3.0

The major benefit: you get updates and its easier to upgrade to the next major release.

Solution 2

you may grab the package from here and install manually:

http://security.ubuntu.com/ubuntu/pool/main/i/icu/

Did you also try this way?

Download from : https://www.microsoft.com/net/download

Then:

mkdir -p $HOME/dotnet
cd Downloads
tar zxf dotnet-sdk-2.0.3-linux-x64.tar.gz -C $HOME/dotnet
export PATH=$PATH:$HOME/dotnet

Verify your installation:

dotnet --version

That package isn't valid for Ubuntu 18.04, there for it isn't valid for Mint 19. Just run the following to get the right version installed and you should be good.

sudo apt install libicu60

https://packages.ubuntu.com/search?keywords=libicu60&searchon=names&suite=bionic§ion=all

And just to add to clarify, this is in fact outlined in the official Microsoft documentation here

With mint 19 I installed dotnet with 'sudo apt-get install dotnet-sdk-2.2'. No unmet dependencies.

+1 - ICU document that "applications that are built with one version of ICU must continue to run without change with later versions of the ICU shared library".

I got prompted that libicu60 is already installed, student18 answer worked for me though.

Downloading the package from the first link worked, i had already tried the second method with no success though.

Thanks for the update! I'll keep this in mind for future installations!

I would add for Linux Mint 20 I opened sudo nano .bash_profile and add the following lines: export PATH=$PATH:$HOME/dotnet and export DOTNET_ROOT=$HOME/.dotnet
