HOW TO?: how to install os.img manually to PINN?

[AureliusBinus]

im on collage learning how to use a raspberry pi 4, but i cant use it after class and its slow as hell to download multiple os when install 1st time.
reason for slow internet. everyone was using the bandwith for download RasPi OS from source and no cache. i dont own a personal pi to install the OS's.

so i need to ask, how to add OS manually cuz i can torrent the images, just idk how to add them to PINN.

PINN does not use images. The images first have to be converted into tar.xz files to separate the files from the partition structure, because the partition structure has to be changed for multi-booting. They also need meta-files to tell PINN how to install the OS.

Most of the OSes are stored on sourceforge at https://sourceforge.net/projects/pinn/files/os/.
Choose an image folder and download the folder and all of its contents.
Store the folder in an /os folder on a USB stick and PINN can install them from there instead of downloading them.
If you download them manually, you may be able to choose a better/faster mirror location to download them from by clicking on the problems downloading? button.

If you can't find the OS you are interested in, please start at https://github.com/procount/pinn-os/blob/master/os/repo_list.json and follow the links til you find the OS you want.

Please see https://github.com/procount/pinn/blob/master/README_PINN.md#local-images-on-usb-stick for more info on installing from USB.

It's a handy website by Matt Huisman to know which OSes are supported and it allowed you to resize each OS's partitions as they were installed, although that functionality is now included by PINN itself. He also did some of the OS conversions.
