Hi @XiCheng ,
from your screenshot you are ROOT v6.16 , not v6.24?

The error you posted is an internet connection error. The installation procedure tries to download some dependencies and fails.

You don’t necessarily have to build ROOT from source to install it on Ubuntu though (in fact we discourage it unless strictly required). You can use the snap or conda packages or the pre-compiled binaries, as described here: Installing ROOT - ROOT .

Cheers,
Enrico
