System dependencies

JetBrains Toolbox is distributed as an AppImage (even though the filename lacks the .AppImage extension), so make sure these dependencies are met: libfuse2 libxi6 libxrender1 libxtst6 mesa-utils libfontconfig libgtk-3-bin tar.

(a) Manual install

Download JetBrains Toolbox from the official website, extract it, add the executable permission, and run it -- it will then copy itself to ~/.local/share/JetBrains/Toolbox/bin, create desktop and autorun entries, and edit your .profile to include its shim folder (so you can run pycharm etc. from the terminal).

(Notably, the shims don't include jetbrains-toolbox itself. If you want that to work (maybe you will disable the autorun?), simply symlink it: ln -s "$HOME/.local/share/JetBrains/Toolbox/bin/jetbrains-toolbox" "$HOME/.local/bin/jetbrains-toolbox")

(b) Install script

There is an install script automating the above process (except the AppImage dependencies), which used to be recommended in the official JetBrains documentation. (It's not there anymore, presumably since it's third-party and they didn't have control over it.)

You can check out the script on GitHub, and you can run it by the command below:

curl -fsSL https://raw.githubusercontent.com/nagygergo/jetbrains-toolbox-install/master/jetbrains-toolbox.sh | bash

So I spent about a month struggling with packages and downloads everywhere, with tons of googling, asking around etc., to no avail. I made this post and within about an hour, messing around in my file manager, completely clueless, I somehow managed to fix this. Welp. Sorry... Here's exactly what I did. Hurray for desperation, I guess?

1. Install the jetbrains-toolbox package from the AUR.

2. Go to /opt/JetBrains/Toolbox (found by looking at the PKGBUILD)

3. Navigate to /opt/JetBrains/Toolbox/bin/ to find jetbrains-toolbox, an executable. I copied this to a folder I made in documents named ToolboxResearch/.
   (Run mkdir -p ~/Documents/ToolboxResearch/Extracted, then run cp /opt/JetBrains/Toolbox/bin/jetbrains-toolbox ~/Documents/ToolboxResearch).

4. Navigate to ~/Documents/ToolboxResearch

5. Extract it using Ark to the Extracted folder.

6. You should have a file hierarchy that looks like so: ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/. I copied this from the file path bar of Thunar, my file manager of choice, so if I made a mistake anywhere up to this point, you can rest assured that this part is correct.

7. To avoid confusing myself with /usr/ and usr/, I ran mv ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/usr ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/store.

8. I edited ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/Jetbrains Toolbox to have these contents:

   Type=Application
   Name=JetBrains Toolbox
   Exec=/home/john/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/store/bin/jetbrains-toolbox %u
   Icon=/store/share/jetbrains-toolbox/toolbox.svg
   StartupNotify=false
   Terminal=true
   MimeType=x-scheme-handler/jetbrains;
   

   The changes I made are specifically limited to Exec, Icon, and Terminal. I changed Terminal to true just to see what it did and I changed Icon and Exec to reflect the new file paths. I highly doubt that this did anything though.

   You will want to change "john" to reflect your home directory instead of mine.

9. I opened ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/store/bin/jetbrains-toolbox (again, copy-pasting from Thunar) in my editor and edited line 5, which starts with path=. I changed it to path=~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/store/share/$app.

10. Navigated to ~/Documents/ToolboxResearch/Extracted/jetbrains-toolbox/store/bin/ in my terminal.

11. Ran ./jetbrains-toolbox

12. It worked!

Sorry for making this post. I Never would've thought that I'd figure this out so soon after I made it. I actually thought I was hopeless.

If someone has this problem and can't fix it even after reading this, you can leave a reply and I'll hopefully be able to help you out. My apologies if this explanation wasn't very clear.
