Ubuntu 20.04 Support

Hi, when reading installation guide for Ubuntu, it seems that ubuntu 20.04 is missing, so how can I install it for Ubuntu 20.04? thank you

You can follow the instructions for Other Ubuntu/Debian Distributions in the README. Pasting the instructions here for convenience:

Download the latest .deb package, and run the following:

sudo dpkg -i <path-to-package>
git-credential-manager-core configure

[felipecrs]

Or also

sudo apt install ./gcmcore.deb

But still, will the updates through apt work when installing directly from the deb?

[felipecrs]

Another point which is important to mention is that it's much harder for scripts to install gcmcore having to download the .deb file.

So that, this would not be needed.

I don't think apt updates will work when you install from the .deb file, but I will test today to verify and circle back.

I stand corrected. I experimented with the following today on a 20.04 machine and it worked...

Part 1: Manually install outdated package

Downloaded an old .deb package (2.0.452)
Then ran the following from my Downloads directory:

sudo dpkg -i gcmcore-linux_amd64.2.0.452.3248.deb
git-credential-manager-core configure

From my terminal:

ldennington@ubuntu:~/Downloads$ git-credential-manager-core --version
2.0.452+b00c5acad3

Part 2: Upgrade using apt-get

curl -sSL https://packages.microsoft.com/config/ubuntu/21.04/prod.list | sudo tee /etc/apt/sources.list.d/microsoft-prod.list
curl -sSL https://packages.microsoft.com/keys/microsoft.asc | sudo tee /etc/apt/trusted.gpg.d/microsoft.asc
sudo apt-get update
sudo apt-get upgrade gcmcore

From my terminal:

ldennington@ubuntu:~/Downloads$ git-credential-manager-core --version
2.0.498+7ad55fb809

The only thing that's wonky here is that, since we're not publishing to a dedicated 20.04 feed, I had to add the 21.04 feed. This feels like I may have been wrong in thinking we should deploy to different repos for different ubuntu versions. Perhaps we should return to the original architecture in which we just deployed to the git feed. @mjcheetham, thoughts?

We don't have any real differences in dependencies between the different distributions, so perhaps the singular git feed would be better?

Our main dependencies are libsecret and dependencies of the .NET runtime itself. We publish GCM against the generic linux-x64 target framework which brings along most (all?) dependencies for the runtime. For libsecret we only depend on it if you opt to use the secretservice credential store, and even then we work with old versions of libsecret.

Closing this issue as Ubuntu 20.04 is supported/works by installing the Debian package downloaded from the releases page.

For tracking apt-get feed support we can use #447
