Can't install libgtk-3-dev for MX Linux MX-19.4_x64

[SwampRabbit]

@JayM thats because they were told to in post #3, the goal was to get everything upgraded to whats in the MX Test Repo.

But I actually think they need to disabled the MX Test Repo and actually downgrade libglvnd-dev. I'm trying to reproduce the mix matching of packages they have, but each time, I can just force the version for libglvnd-dev and the likes back to the stable repo and everything installs back fine.

Now I don't know if that will affect their Nvidia install, it may if it needs a specific version of libglvnd0, can't fully test that as I don't have anything with Nvidia at the moment.

This may be why:

Code: Select all

           Active apt repos in: /etc/apt/sources.list.d/mx.list 
           1: deb http://mirror.truenetwork.ru/mxlinux/mx/repo/ buster main non-free
           2: deb-src http://mirror.truenetwork.ru/mxlinux/mx/repo/ buster main non-free
           3: deb http://mirror.truenetwork.ru/mxlinux/mx/testrepo/ buster test
           4: deb-src http://mirror.truenetwork.ru/mxlinux/mx/testrepo/ buster test

You've permanently enabled the MX Test Repo. Don't do that! Now apt is all confused about where to install things from. Just use MX Package Installer. First though, run MX Repo Manager and disable the test repo, then open a terminal and run

Code: Select all

sudo apt update

(and you don't need the source repos either.)

Thanks - I've turn off test repo but it doesn't help:

How can I downgrade libglvnd-dev?

libegl1-mesa-dev isn't in the Test repo, it should install from the Main repo.
It can get tricky when Test libraries are installed and then you decide to build programs yourself and need the matching -dev packages

I suggest to remove nvidia driver from test repo or at least make attention like yours - It can get tricky when Test libraries are installed and then you decide to build programs yourself and need the matching -dev packages. Now I need reinstall all my mxlinux to fix it. Oh my God!

You don't have to enable the Test repo to install the nvidia driver from there
You use the Nvidia Driver Installer app in the MX Tools section of the menu.

May be test repo was enabled automatically - there was the question about install newest mx-nvidia-driver and I agreed with it.

The MX Test Repo is enabled temporarily, then it is disabled by the Nvidia Driver Installer. No one forces anyone to install the drivers or anything else from the MX Test Repo, its called Test for a reason. Its for testing userend applications, not testing develpment items. While 99.99% of the time it isn't an issue, rare situations do occur, but honestly I can verify if the Nvidia Driver Installer caused this because I don't have Nvidia devices.


Now to downgrade at least libglvnd-dev back to where it needs to be, you can use Synaptic (make sure you disable the MX Test Repo) since you enabled it recently, I tested this by first upgrading to packages in the MX Test Repo.

Then I:
- searched for glvnd-dev > highlighted it
- clicked "Package" in the menu
- chose "Force Version" which gives me options
- selected 1.1.0-1
- applied

Now at this point it complained a lot about downgrading packages and removing packages.
If you decide to go this route, please make a note of the packages it is removing so you can reinstall them (using the Stable repo of course).

After this I was able to install libepoxy-dev, libgtk-3-dev without issue both using MXPI Stable Repo tab and Synaptic.

If you're trying to build programs yourself, you should know how to not create or resolve package conflicts when mixing and matching package versions.

Users should always ensure they have backups or use applications like Timeshift to roll back to know good points, even if they don't use anything from the MX Test Repo or not, its just good practice.

libglvnd-dev has only 1.1.0-1 version, can't chose (see) another and that is why can't select, I can freeze it only, but it doesn't help. Please see below:

sudo apt-get install libglvnd-dev

i think it is too late... By the way I haven't chose test repo manualy - only install newest nvidia driver and then made update. May be that is the reason of my deep test system.

That is what I am saying, you need to force libglvnd-dev to 1.1.0-1 and then reinstall everything that is removed, but make sure your install them from the Stable repo.

Now I just did a test and installed a ton of Nvidia packages from the MX Test Repo using MXPI (because I don't have Nvidia hardware and can't use the Nvidia Drive Installer).

Nothing I installed or updated libglvnd0, libglvnd-core-dev, or libglvnd-dev, so I don't know how you got those.

So until someone can prove otherwise, I don't think using the Nvidia Driver Installer actually installs or upgrades those, it would have had to be done manually somehow.

At this point you can do two things:
1) downgrade those packages and reinstall the ones removed, install Timeshift to make sure you take snapshots when possibly installing something which may conflict later, and don't use the MX Test Repo if you need libgtk-3-dev.
2) reinstall MX, install Timeshift to make sure you take snapshots when possibly installing something which may conflict later, and don't use the MX Test Repo if you need libgtk-3-dev.
