@mrichards3 rpms for RHEL should be available this week. We'll update those instructions once they are available.

@leecow getting a 404 on the link to the blog post. Thinking that it might be correct, but just not published yet?

uffebjorklund on 30 May 2018

Link to "Known Issues" from here is also returning 404.

@uffebjorklund and @winzig - both should be up now.

Link to https://github.com/dotnet/core/blob/master/release-notes/2.1/api-diff/rc1/2.1.md is broken in https://github.com/dotnet/core/blob/master/release-notes/2.1/2.1.0.md#api-changes

Looks like it should have been https://github.com/dotnet/core/blob/master/release-notes/2.1/api-diff/2.0-vs-2.1.md.

The ubuntu packages for bionic seem to be missing "dotnet-sdk-2.1.300" and reverts to installing the preview. It looks like the package "dotnet-sdk-2.1" is pointing to the correct deb file though.

@annymsMthd - We need to make an update to the install instructions so to refer to dotnet-sdk-2.1. This is part of the update to make the installers behave themselves for updates. I've changed the download page on github but need to look at https://www.microsoft.com/net/download/linux-package-manager.

I have a weird issue with the trusty repo (perhaps other ubuntu repos are also affected)..

I'm using a mirroring too to mirror the entire repo for installation inside a segragated network consisting of hundreds of machines.

Unfortunately, one of packages in the repo seems to have a bad hash value in the Packages file...

While the package itself (addlogin) is not a dependency of dotnet-sdk-2.1.300 in itself, the mirroring tool has no way of knowing this, and fails on the hash mismatch regardless...

Here's is the information:

The 2.1.200 SDK depends on "aadlogin-selinux_1.0.004870001_amd64.deb" but the hash mismatches

General

When I do:

I'm guessing something got messed up?

damageboy on 30 May 2018

@damageboy - I'll check with the product repo owners with respect to the hash.

Where are you seeing that the SDK has a dependency on aadlogin? The only defined dependencies are on aspnetcore-runtime and dotnet-runtime and it's not a dependency through any of the other packages.

Also, do you mind if I pull your comment up into an issue by itself?

leecow on 31 May 2018

While installing .NET Core 2.1 in Fedora 27, I can see some dependent packages are RC version. Is it expected?

dotnet-sdk 2.1.300 still show an outdated message when first init.
dotnet tool install dotnet-dev-certs -g --version 2.1.0-preview1-final(Not sure what's the full message in English, so only include the command here)

Maybe it's no longer needed as I can found it in C:\Program Files\dotnet\sdk\2.1.300\DotnetTools, and can be run with dotnet dev-certs, seems it's also include in sdk like dotnet ef does.

Updated: I see the message was removed in https://github.com/dotnet/cli/pull/8957, but the translations are never updated, so the message still left for all other languages.

The Known Issues page does not list a known issue we hit (and a pretty big one). The Alpine .NET Core images will segfault on a host running with SELinux on. https://github.com/dotnet/dotnet-docker/issues/561

gortok on 31 May 2018

@leecow
As for where I'm seeing this...
Again, this is a bit of a non-standard situation.
I'm seeing this while attempting to create a mirror of the repo... using an apt mirroring tool.

That is why even if there is NO dependency on addlogin through, for example, installing dotnet-sdk-2.1.300... The mirroring tool doesn't care or know about that. As far as a mirroring tool would be concerned it's all or nothing. And the moment it sees an hash mismatch on the Package release files, it's game over.

Again... Stressing that this is a less than standard situation, since what is failing is the apt repo MIRRORING rather than the installation.

I've previously opened an issue about this before, during the RC1 phase...
Here it is: https://github.com/dotnet/core/issues/1530

Looks like .NET Core 2.1 is broken on Arch Linux.

You likely need to copy aspnet into the right location. Should work if you do that an console apps run fine.

This page doesn't have instructions or package links for .NET Core 2.1 in the "Install .NET Core for supported Red Hat Enterprise Linux (RHEL) versions" section:
https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x#install-net-core-for-supported-red-hat-enterprise-linux-rhel-versions

Are the RHEL packages still being finalized for .NET Core 2.1?

It looks like the release candidate files were removed and replaced by the official release files. The yum package for dotnet-sdk-2.1.0 should be updated to download the new files.

To add to what @KevinKibler said, it looks like the dependency tree still refers to some of the rc files that were deleted. You can reproduce this easily with docker:

docker run --rm centos:7 bash -c "rpm -Uvh https://packages.microsoft.com/config/rhel/7/packages-microsoft-prod.rpm && yum -y update && yum install -y https://packages.microsoft.com/rhel/7/prod/dotnet-sdk-2.1.300-x64.rpm"

I'm getting the same error downloading a previous release using
sudo yum install dotnet-runtime-2.0.7

Can someone fix this please? and maybe a test should be written for this...

stephenetyler on 5 Jun 2018

I am getting the same issue as well, with any flavor of 2.1.x

thanks

johndesp on 5 Jun 2018

Also having the same issue with missing dotnet-host-2.1.0_rc1 and dotnet-runtime-deps-2.1.0-rc1 packages.

You can work around it by explicitly installing version 2.1.0-1 of dotnet-host before installing the main sdk / runtime package. For example yum install dotnet-host-2.1.0-1 dotnet-sdk-2.1

Probably related to work being done in #1620 :

We're in the process of removing the pre-release versions of dotnet-host-2.1.0 from the product feeds and this issue will be closed once that is complete.

gnjack on 6 Jun 2018

@mrichards3 - yes, the RHEL release is still being finalized. Talked with the Red Hat folks yesterday and they're on track to release next week.

leecow on 6 Jun 2018

The RHEL rpms are available, you can install and use .NET Core 2.1 as follows:

$ sudo yum install rh-dotnet21 -y
$ scl enable rh-dotnet21 bash

RHEL container images (and documentation) are expected in 1 to 2 weeks.

Closing this issue now that 2.1.1 is released.
