In this guide, i show you, how you can easily become independent from APT repositories from Internet, having only Debian or Devuan ISO-file.
I show this on Devuan, because it's having a DESKTOP image, with 4 GB of packages.
We are need to mount this ISO. If you have a free USB Media, you can write Devuan on it, with
dd, but you can just write
mount ./*Path to ISO* ./*directory to mount*
And, that's all.
And, the last, that we need - it's write path to /etc/apt/sources.list. Wite something like this:
deb [trusted=yes] file:/*Path to mount directory* chimaera main contrib
It should like something like that:
deb [trusted=yes] file:/media/cdrom chimaera main contrib.
Now, updating with
sudo apt update. And, now you can disable other repos.
4700+ Packages with few DEs, and other software, enought to just use computer, all other can be compiled from source.
