I tried installing Forge on Linux on the Minecraft installation I got through the flathub repo and when trying to launch the game I get a error stating the following:
Failed to start download.
Name: 1.16.4-forge-35.1.36.jar
URL: https://launcher.mojang.com/v1/objects/1952d94a0784e7abda230aae6a1e8fc0522dba99/client.jar
Error details: Permission denied Couldn't open file for download Filename on disk: 1.16.4-forge-35.1.36.jar
Path: /home/antoniochavez/.var/app/com.mojang.Minecraft/data/minecraft/versions/1.16.4-forge-35.1.36/1.16.4-forge-35.1.36.jar
Exists: Nonexistent
I manually checked the directory to see if the jar file did install to which it did but I wasn't able to change the folder's permissions even after tryin chmod +x (every subfolder in the Minecraft directory). Is this a problem on Forge's end or a problem with using a Flatpak seeing as the changing of permissions wasn't required when I installed it as a Snap under Ubuntu?
