runtime: Can't install latest dotnet-sdk in Windows Subsystem for Linux

at what step did the error occur?

Thank you for asking @blackrek

1. sudo apt-get autoremove dotnet-host
2. sudo rm -rf /usr/share/dotnet/
3. wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu60_60.2-6ubuntu1_amd64.deb dpkg -i libicu60_60.2-6ubuntu1_amd64.deb

Also http://mirrors.edge.kernel.org/ubuntu/pool/main/i/icu/ is not found

This answer worked for me, but I had to break step 3 into to parts: 3a. wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu60_60.2-6ubuntu1_amd64.deb 3b. sudo dpkg -i libicu60_60.2-6ubuntu1_amd64.deb

1. sudo apt-get install dotnet-sdk-2.1 Output: Reading package lists… Done Building dependency tree Reading state information… Done The following additional packages will be installed: aspnetcore-runtime-2.1 dotnet-host dotnet-hostfxr-2.1 dotnet-runtime-2.1 dotnet-runtime-deps-2.1 liblttng-ust-ctl2 liblttng-ust0 liburcu4 The following NEW packages will be installed: aspnetcore-runtime-2.1 dotnet-host dotnet-hostfxr-2.1 dotnet-runtime-2.1 dotnet-runtime-deps-2.1 dotnet-sdk-2.1 liblttng-ust-ctl2 liblttng-ust0 liburcu4 0 upgraded, 9 newly installed, 0 to remove and 107 not upgraded.

To get it to install on Ubuntu 18.04 I had to run the following before attempting the dotnet-sdk-2.1 install: wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb sudo sudo dpkg -i libicu55_55.1-7_amd64.deb

Installing libicu60 didn’t resolve the missing dependency for me.

fixed for ubuntu server 18.04 for dotnet-sdk-2.1

1. remove old version (thx @leecow comments):

sudo apt-get autoremove dotnet-host starts at the bottom of the dependency tree rather than the top and will do most of the work. sudo rm -rf /usr/share/dotnet/ to clear up the remaining things in the sdk/ directory.

1. fix @jefking instructions (replace package version for libicu60): wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu60_60.2-6ubuntu1_amd64.deb dpkg -i libicu60_60.2-6ubuntu1_amd64.deb

(if you need other version of libicu, just found it in http://mirrors.edge.kernel.org/ubuntu/pool/main/i/icu/)

1. now apt-get install dotnet-sdk-2.1 works!

today installed 2.1.302 version thx all!

Fixed my issue above

Found this: No installation candidate for “libicu52” on 15.10

Ran

wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu52_52.1-3ubuntu0.8_amd64.deb
dpkg -i libicu52*.deb

Then

sudo apt-get install dotnet-sdk-2.1

Looks like some package wiring was missing, but specifying a few transitive deps explicitly seemed to work for me…

#!/bin/bash wget https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb sudo dpkg -i packages-microsoft-prod.deb sudo dpkg -i libicu55_55.1-7_amd64.deb sudo add-apt-repository universe sudo apt-get install -y apt-transport-https sudo apt-get update sudo apt-get install -y dotnet-sdk-2.1 dotnet-runtime-2.1 aspnetcore-runtime-2.1 dotnet-runtime-deps-2.1 libicu55

I also had the same error as CoskunSunali. …

Are not these additional steps better to be a part of the documentation at https://dotnet.microsoft.com/download/linux-package-manager/ubuntu18-04/sdk-2.2.105 or even better set as dependencies so apt or apt-get installs them automatically?

It is 2019 and we have to search through Google to figure out how to install dotnet-sdk using a package manager. Feels sad.

By the way, even after invoking the workaround commands, it fails.

@EdenRidgway thanks! your solution worked for me. sudo wget http://mirrors.kernel.org/ubuntu/pool/main/i/icu/libicu55_55.1-7_amd64.deb

Actually this version is what solves the issue for ubuntu 18.

I am having this same issue–I have rc1 installed (using aptitude because apt-get failed) and am now attempting to install 2.1 using sudo apt-get install dotnet-sdk-2.1. This errored out with the same message on both my laptop (Surface) and my personal desktop (also Windows) on Ubuntu/bash. As noted above, worked fine using aptitude, a solution proposed in this post by someone having the same problem: https://askubuntu.com/questions/363200/e-unable-to-correct-problems-you-have-held-broken-packages/451078. While this is a functional workaround, it would be nice to know what is going on here as it seems like the problem is occurring for a number of WSL users.
