How to remove previous versions of .NET Core from Linux (CentOS 7.1)

Question

I would like to install the current version Core 1.0. Currently the RC2 version is installed. The instruction on the official website are:

Before you start, please remove any previous versions of .NET Core from your system.

But I don't know how and I can't find nothing from Microsoft like for example here.

I found this script... but my Linux skills are not great and I won't make it worst.

Answer 1

Sometimes it can be so simple! In order to remove the previous installation, simply remove the dotnet folder from where you installed it on disk.

Answer 2

You need to do this over the package manager, otherwise, you end up with a broken system.

This is for Ubuntu/Debian/Mint:

To list all installed packages

sudo apt --installed list

To list all the packages you installed

sudo apt --installed list | grep "dotnet-dev"

to remove a specific package

sudo apt-get remove --purge PACKAGE_NAME 

e.g.

sudo apt-get remove --purge dotnet-dev-1.0.1

For other distros, consult the Packman-Rosetta-Stone

Ok, this make sense, but what if i install it via dotnet-install.sh ? how i can uninstall it or update? – Veratrine

In CentOS you would do the following:

1 - Find the package installed

yum list installed | grep "aspnet"

2 - Remove the package

yum remove aspnetcore-store-2.0.0.x86_64

On Ubuntu:

First list the dotnet packages installed:

$ sudo apt --installed list | grep "dotnet"

You'll have a result like this:

dotnet-apphost-pack-3.0    dotnet-hostfxr-3.1         dotnet-runtime-deps-5.0
dotnet-apphost-pack-3.1    dotnet-hostfxr-5.0         dotnet-sdk-5.0
dotnet-apphost-pack-5.0    dotnet-runtime-5.0         dotnet-targeting-pack-3.0
dotnet-host                dotnet-runtime-deps-2.2    dotnet-targeting-pack-3.1
dotnet-hostfxr-2.2         dotnet-runtime-deps-3.0    dotnet-targeting-pack-5.0
dotnet-hostfxr-3.0         dotnet-runtime-deps-3.1 

To uninstall the packages of linked to version 3 for example just type:

$ sudo apt-get remove --purge dotnet-*3*

For any CentOS users, the yum command is used to install/uninstall packages, here is how you do it in CentOS:

yum remove dotnet-sdk-2.0.0

Answer 6

Here is what I found on MSDN and It worked for me as charm. First list the install SDKs using below command

dotnet --list-sdks

Then run below set of commands after updating version as found in above command.

version="1.0.1"
sudo rm -rf /usr/share/dotnet/sdk/$version
sudo rm -rf /usr/share/dotnet/shared/Microsoft.NETCore.App/$version
sudo rm -rf /usr/share/dotnet/shared/Microsoft.AspNetCore.All/$version
sudo rm -rf /usr/share/dotnet/shared/Microsoft.AspNetCore.App/$version
sudo rm -rf /usr/share/dotnet/host/fxr/$version

Today I was uninstalling old version of dotnet on my Linux Mint. First I typed:

$ sudo apt remove dotnet

Then I pressed tab. It showed all related packages. I simply copied them and pasted:

$ sudo apt remove dotnet-host dotnet-runtime-2.2 dotnet-sdk-2.2 dotnet-hostfxr-2.2 dotnet-runtime-deps-2.2 

I guess in Fedora/CentOS, the procedure is same. Just use yum instead of apt. I hope this helps. :)
