I tried to install HyprV4 on Monday (12th of August 2024). Before running the script I installed as many packages as possible from the official Arch repositories, including swaylock.
But, when the script tries to install swaylock-effects, it returns an error, and in the install.log it says that the package conflicts with swaylock.
I haven’t yet tested deleting this package from the script and attempting to run it with the swaylock package installed instead. I’ll report the results tomorrow.
