Created on 25 Jul 2016 · 25Comments · Source: dotnet/sdk

Ported issue from https://github.com/dotnet/corefx/issues/10295 from @AlexisColes:

Trying to follow the getting started guide https://www.microsoft.com/net/core#ubuntu

When I run sudo apt-get update I get the following

Then try running the sudo apt-get install dotnet-dev-1.0.0-preview2-003121 and get the following:

alexis@UbDscTest1:~$ sudo apt-get install dotnet-dev-1.0.0-preview2-003121
[sudo] password for alexis:
Reading package lists... Done

E: Unable to locate package dotnet-dev-1.0.0-preview2-003121

E: Couldn't find any package by regex 'dotnet-dev-1.0.0-preview2-003121'

Not quite sure what I have done wrong, please help.

My solution for this was using http instead of https for this line:
sudo sh -c 'echo "deb [arch=amd64] http://apt-mo.trafficmanager.net/repos/dotnet-release/ xenial main" > /etc/apt/sources.list.d/dotnetdev.list'

I can see the release file present here:
https://apt-mo.trafficmanager.net/repos/dotnet-release/dists/xenial/Release

@AlexisColes Can you please run ping apt-mo.trafficmanager.net so we can see which cdn you are hitting?

@chuan FYI
This looks like a potential issue with certs again.

@chuan @brthor I'm also failing to ping apt-mo.trafficmanager.net. I am getting redirected to apt-wus.cloudapp.net, however.

I am also getting same error.. Is there any update on this..? how to resolve it ?

rambabugupta on 27 Jul 2016

The redirect is expected. apt-mo.trafficmanager.net redirects to replicated cdns depending on your location.

@piotrpMSFT I am also redirected to apt-wus.cloudapp.net
I'm unable to repro against that endpoint.

Working on a repro against apt-wu endpoint

brthor on 27 Jul 2016

I'm unable to obtain a repro here.

@AlexisColes @ramboforever
As a first step, can you ensure the ca-certificates package is installed, and attempt reinstalling if it already is.

apt-get install ca-certificates
apt-get install --reinstall ca-certificates

alexis@UbDscTest1:~$ sudo apt-get install ca-certificates
[sudo] password for alexis:

ca-certificates is already the newest version (20160104ubuntu1).

So I have run the reinstall command and it seemed to re-install fine.

However running sudo apt-get update and sudo apt-get install dotnet-dev-1.0.0-preview2-003121 give the same results as before.

However I forgot to mention that we have all external ports closed apart from 80 and 443. Which is why the previous ping did not get a response.

To that end when running the sudo apt-key adv --keyserver apt-mo.trafficmanager.net --recv-keys 417A0893 command it failed. I had to run the command sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 417A0893 as suggested in this issue: https://github.com/dotnet/cli/issues/2189

AlexisColes on 28 Jul 2016

Any updates on this?
I am also getting the errors on:
E: Unable to locate package dotnet-dev-1.0.0-preview2-003121
E: Couldn't find any package by glob 'dotnet-dev-1.0.0-preview2-003121'
E: Couldn't find any package by regex 'dotnet-dev-1.0.0-preview2-003121'

I walked through the cert install and reinstall. No issues doing that but still cannot find the release to install of dotnet

Is there anything interesting about your ubuntu 16 system?
What packages do you have installed?
Is it a VM, machine installation?

I cannot repro this in an azure VM or docker container.

Welcome to the new and insane world.

Think I know what's going on here @bartelia & @brthor . I've hit the same issue myself, I'm using Linode for my VPS. My VPS has been up and running since the 10.04 days and started out as a i386 machine. I have after that upgraded to every LTS release and along the way I switch the kernel to be x64 sometime ago as well.

Now, the interesting part here is that my apt version tells me it's i386 whereas my kernel is x64. Hence, it will never download the metadata for dotnet core since it has the arch=amd64 tag on it in the sources file, and only supports true x64 systems. See below outputs.

$ apt --version
apt 1.2.12 (i386)

$ uname -a
Linux [RETRACTED] 4.6.5-x86_64-linode71 dotnet/sdk#4284 SMP Fri Jul 29 16:16:25 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux

Check your system as well, maybe you've hit the same thing here?

@eldenis
Thank you, but still doesn't work

E: Unable to locate package dotnet-dev-1.0.0-preview2-003131

Hey Admin,
How do you expect Linux user (And Ubuntu is the biggest one) to use and love ASP.NET Core, if they even cannot install it.

alzearafat on 13 Oct 2016

@eldenis This work for me. Thank you.
@alzearafat I ran sudo apt-get update after @eldenis's script and it worked.

@eldenis Thanks! it works for me.

Seems like this is working for people. And I tried it in a Linux subsystem yesterday and installation worked.

Just came here to say that it does not work with https only with http again.

The issue still present, today ^^

MichalTaratuta on 17 Oct 2017

@MichalTaratuta this issue is about a preview version. What is the version you are using and having the problem?

Kali Distribution also appears to have this issue--

Here's what I did to get this working. Based on the current installation instructions (https://www.microsoft.com/net/learn/get-started/linuxubuntu), the guide says to do the following:

curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg

What I did instead is the following:

curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -

Now, apt can validate the signatures when I perform apt-get upgrade.
