Apt keeps uninstalling dotnet6 and your docs make NO MENTION of this insane behavior #31056

Closed archer884 closed 2 years ago

archer884 commented 2 years ago

What else can I say? I install dotnet6, I use it, and then I realize my discord installation stopped working. I install discord, I use that, and then I realize that dotnet6 stopped working... I have no idea what in the hell is going on but, the way your package works, it seems perfectly happy to remove the SDK and literally everything EXCEPT for the dotnet tool itself, which will then helpfully tell me that I have no SDKs the next time I try to compile something.

Well, I did have them, but they were marked as automatically installed and unused, and so apt very nicely deleted them the last time I installed anything!

No clue what's going on. Don't care. Tired of dealing with it. Your docs didn't help in the least.

Hello, sorry this issue fell through the cracks and you've probably moved on...

My initial thought would be that there is some sort of dependency conflict between the two programs and perhaps each is stepping on the other? Did you contact Discord about the problem?

What specifically do you think needs to be mentioned in the docs? If the APT system isn't working well and uninstalling everything dotnet installed, I'm not seeing anything reported in the .NET product repo: https://github.com/dotnet/sdk/issues?q=is%3Aissue+uninstall+ubuntu+is%3Aopen

Other information is important, such as how were you installing .NET? Did you install just the SDK or did you install a runtime too? Did you upgrade different versions of .NET? Which version of Ubuntu are you working with?

archer884 commented 2 years ago

I've been installing the SDK via the following command:

❯ sudo apt install dotnet

I wasn't aware it was possible to install it WITHOUT a runtime. You can see the packages installed in the log below. (Of course, in that log they're being uninstalled.)

You're getting your packages from http://apt.pop-os.org so I would take it up with them as they're the ones in charge of the feed + dependencies you're installing. If you're installing packages from multiple feeds, it's always possible you run into these weird dependency issues. I think that's just the nature of Linux. You'll need to work with the APT settings to pin packages and dependencies and prevent uninstall. Some options I can think of:

  1. Ask the pop-os folks for support.
  2. Prioritize Ubuntu's feed if it works on your derived distro, meaning, install both dotnet6 and discord from the official ubuntu feeds and not from pop-os' feeds.
  3. Install and use the Microsoft feed for dotnet, that might work.
  4. Try getting support on Stackoverflow to understand how to configure and prevent Linux from uninstalling dependencies: https://unix.stackexchange.com/questions/63826/how-to-stop-apt-from-uninstalling-the-packages-while-updating
  5. Try using the .NET manual install script to install the SDK instead of relying on the apt packages.
  6. Ask the .NET product team for support: https://github.com/dotnet/sdk/issues

Unfortunately, you're using a distro we don't support installing .NET via APT. I also don't have any experience with this distro so I can't really offer any help. The official recommendation for installing .NET on an unsupported Linux distro is to use the install script. (although I have seen some issues in the .NET product team repo related to pop os, so they may help you there)

I'm going to close this issue because there isn't anything we can do on the docs side for your issue. But please reply and let me know what you did and if you ever get it working, then I can at least guide anyone else in the future that runs into your same situation.

Sorry!
