So litecoincash is out. Let's not waste time in what it's and what is not, this post is a simple guide to start and run litecoincash core wallet in a gnu/linux machine. I'm using debian. The wallet will not be installed system wide, but used in a folder as a user process, so no root is required and risk of affecting the system is minimal. If you still don't feel confident, just run it in a virtual machine.
download the wallet from the website
extract it either by right clicking on the folder and "extract" or cd into the folder and tar -xf litecoincash-0.15.0-x86_64-linux-gnu.tar.gz
cd into the folder or go normally into the folder and open terminal there
once in the folder with the terminal type ./litecoincash-qt
You will be asked where to place the data dir. I'd say stick for the common and put it in ~/.litecoincash
Add a list of peers to the wallet. Settings > Options > Open configuration file and paste the following. Be careful: it could be dangerous to add malicious nodes, so I'm posting this here in good faith and it is my personal node list, but do your own research and see who to trust. This will speed it up quite much.

bootstrap.dat.zip in the ~/.litecoincash folder and extract it there either by right click > extract here or unzip bootstrap.dat.zip./litecoincash-qt -datadir=/home/user/.litecoincash -loadblock=/home/user/.litecoincash/bootstrap.datUse absolute path as I've seen that using ~ as /home/user/ is not recognized.
Let it sync, it will take few hours
