So I'm trying to compile Aseprite, and I'm unable to install a package I need in this process: libx11-dev. Here is the output for "sudo apt install libx11-dev"
sudo apt install libx11-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libx11-dev : Depends: libx11-6 (= 2:1.6.4-3ubuntu0.1) but 2:1.6.4-3ubuntu0.2 is to be installed
Depends: libxcb1-dev but it is not going to be installed
Recommends: libx11-doc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
There are two unmet dependencies. Next I tried installing the first dependency, libx11-6
sudo apt install libx11-6
Reading package lists... Done
Building dependency tree
Reading state information... Done
libx11-6 is already the newest version (2:1.6.4-3ubuntu0.2).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
As you can see it is already installed, and it is also the latest version, 2:1.6.4-3ubuntu0.2. This seems to be the required version, as you can see in the first message. A similar problem happens with the second "unmet" dependency.
It seems the problem is that I have held broken packages. I have tried many things to fix this, but as far as I can tell, I am not holding any broken packages. When I try:
dpkg --get-selections | grep hold
There is no output. Similarly "sudo apt install -f" does not fix anything.
Here are more outputs that may help
