cannot install dotnet-sdk-2.1 on ubuntu (404 not found)

TLDR;

sudo apt install dotnet-sdk-2.1 is causing the following error:

E: Failed to fetch https://packages.microsoft.com/ubuntu/18.04/prod/pool/main/d/dotnet-sdk-2.1/dotnet-sdk-2.1.701-x64.deb  404  Not Found [IP: 13.91.48.226 443]

Detail of problem

This morning I updated my Ubuntu 18.04 machine (sudo apt -y upgrade) and received the following error:

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

So I uninstalled dotnet and reinstalled dotnet:

# uninstall script
curl -OL https://github.com/raw/dotnet/cli/master/scripts/obtain/uninstall/dotnet-uninstall-debian-packages.sh
chmod u+x dotnet-uninstall-debian-packages.sh
sudo ./dotnet-uninstall-debian-packages.sh

# remove remaining folders
sudo rm -rf /usr/share/dotnet
sudo rm -rf ~/.dotnet

# uninstall package including config file
dpkg -P packages-microsoft-prod
sudo apt update

I then attempted to reinstall dotnet

wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo add-apt-repository universe
sudo apt-get install apt-transport-https
sudo apt update
sudo apt install dotnet-sdk-2.2
sudo apt install dotnet-sdk-2.1

However, sudo apt install dotnet-sdk-2.1 gives me the same error as when I first performed sudo apt -y upgrade this morning (which was the reason why I uninstalled and reinstalled dotnet).

Thanks for filing with the extra info!

@leecow, is it possible the recent release left the feed in an inconsistent state? Or is it not done yet, and this is unlucky timing? (If so, the order things are uploaded in is questionable.)

For example, in https://packages.microsoft.com/ubuntu/18.04/prod/dists/bionic/main/binary-amd64/Packages, I see:

But there is no such deb, per above: https://packages.microsoft.com/ubuntu/18.04/prod/pool/main/d/dotnet-sdk-2.1/dotnet-sdk-2.1.701-x64.deb

Max is dotnet-sdk-2.1.700-x64.deb in https://packages.microsoft.com/ubuntu/18.04/prod/pool/main/d/dotnet-sdk-2.1/.

The repos are still updating so are in an inconsistent state at the moment.

[leecow]

Just tested installing 2.1.701 on 18.04 and things look good there.

[dagood]

Works for me now in a fresh 18.04 Docker container.

Are the package repo maintainers aware of the service disruption this causes, any plans to mitigate? From the outside, it seems obvious that the deb packages should be uploaded before the index is updated, but there of course might be more to it.

[kimbaudi]

oh wow, that is so strange. it is working now!

I entered the following command just now:

wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo add-apt-repository universe
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-2.1

it is the same exact command as before... i guess just unlucky timing. 😅

Ubuntu 16.04 packages still broken?
E: Failed to fetch https://packages.microsoft.com/ubuntu/16.04/prod/dists/xenial/main/binary-amd64/Packages.bz2 Hash Sum mismatch
E: Some index files failed to download. They have been ignored, or old ones used instead.

I was having this problem earlier (first time, with dotnet-sdk-2.1, then later with dotnet-sdk-2.2). It must have been about 2 hours ago. But I just ran sudo apt upgrade right now, and it just upgraded dotnet-sdk-2.2 without a problem. @ColinPM I suggest you wait it out.

[ColinPM]

Thanks kimbaudi, I saw your comments and that the ticket for your issue was closed :-) Interestingly, I saw the server timestamps change this evening when I refreshed my browser so the team must still be updating the packages. Your advice to wait it out is appreciated and, I think, ultimately correct.
