Hello!
I am new user to Endless OS and i would like to spare disk space. Is that possible and how?
I attach you eos-diagnostics for your better convenience.

Hello, and thanks for being a user of Endless OS! 
I’m happy to help out, but I’d like to better understand what you’re trying to do. According to your log file (thank you for attaching it!), it looks like you have a 128 GB drive with about 80 GB of free space. Are you looking for ways to free up more space?
Best,
Cassidy
Exactly! Especially after each endless os update, a guide of how to free space would help a lot!
Perhaps endless os community could write an official guide similar to that for Microsoft Windows

Hey @asimkon ,
Just to be sure you know:
Updates add new software to your system, which costs disk space, but they also remove data that’s not needed anymore.
So your disk isn’t filled up just by doing updates 
Hello!
I attach you a recent screenshot from disk usage analyzer. I think that ostree deployment 34.2 GB is too much.
Is something that could be done?
Regards
Those are your apps, not the OS itself: note /var/lib/flatpak in the path.
You can uninstall some large apps you don’t use.
