These are 2 commands I ran trying to install .net core 6.0 on CentOS 8 Stream:
sudo dnf install dotnet-runtime-6.0 Last metadata expiration check: 0:12:04 ago on Tue 23 Nov 2021 17:38:47 UTC. . . . Installed: dotnet-host-6.0.0-0.6.28be3e9a006d90d8c6e87d4353b77882829df718.el8.x86_64 dotnet-hostfxr-6.0-6.0.0-0.6.28be3e9a006d90d8c6e87d4353b77882829df718.el8.x86_64 dotnet-runtime-6.0-6.0.0-0.6.28be3e9a006d90d8c6e87d4353b77882829df718.el8.x86_64 lttng-ust-2.8.1-11.el8.x86_64 userspace-rcu-0.10.1-4.el8.x86_64 Complete! [/usr/local/bin]$ dotnet --list-runtimes Microsoft.NETCore.App 6.0.0-rc.2.21470.23 [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
Install says it installed
6.0.0-0.6 but the actual version is
6.0.0-rc.2.21470.23 and my app is failing with error:
It was not possible to find any compatible framework version The framework 'Microsoft.NETCore.App', version '6.0.0' (x64) was not found. - The following frameworks were found: 6.0.0-rc.2.21470.23 at [/usr/lib64/dotnet/shared/Microsoft.NETCore.App]
Can it be fixed without manual .net install ?
add repo to the OS: sudo rpm -Uvh https://packages.microsoft.com/config/centos/8/packages-microsoft-prod.rpm
change it priority to preceed the OS: echo ‘priority=50’ | sudo tee -a /etc/yum.repos.d/microsoft-prod.repo
install sudo dnf install dotnet-runtime-6.0
reboot the machine
CentOS 8 Stream seems to have an out-of-date version of .NET 6.
That the version is old is kind of my fault; I need to update the package in CentOS Stream 8 (which really copies what’s in RHEL 8.6 and that’s the one I will fix).
The version showed by
dotnet --info is correct.
The RPM package versioning is a workaround in that CentOS (and RHEL and Fedora until recently) don’t have a way of reflecting pre-release versions of an upstream that is about to a release 6.0. We are forced to use a version “6.0” and Release with “0.X” to say “this is a pre-release of 6.0”. I could have called it “6.0-0.6.rc2”, but this build isn’t even exact “6.0 RC2”, it was a pre-RC2 snaphost (commit
28be3e9a006d90d8c6e87d4353b77882829df718 from dotnet/installer repository).
If you urgently need .NET 6, here are some options to consider:
If you need a container, try out
Use a manual (not package) install of .NET 6: https://docs.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#manual-install
