after installing applications from pamac cli and gui, the gui shows that the application is installed but i cannot find it in the application launcher or anywhere else by search even though pamac shows it is installed.
edit: can run the application by launching it from cli
Without knowing which applications you are referring to, it is highly likely that the applications you installed were command-line utilities, not GUI applications, and as such, they won’t get added to any application launcher menus.
Could you be more specific about which applications you are referring to, and whether they were from the official Manjaro repositories, or from the AUR, or installed via Snap or FlatPak, or as an AppImage?
You do have an open source variant of it in the official repository (community/code) - sudo pacman -S code - which is better than AUR (unrelated to this problem), unelss you really need the MS variant (I forgot the details, there’re some limitations with what you get by default but all can be easily worked around, I think).
I forgot all the details, as I have it all setup so was a while since I did that, but read about it online but there is a fix for that, as it’s only the marketplace ‘links’ that are missing and those files can be patched on the machine. Here is one link fast (AUR (en) - code-marketplace) but something along those lines (I think I’ve used something else but similar), so you pretty much can have a normal marketplace. At least you should research, try, depending on what you need, as it pays off having something in the official repo instead of AUR.
