I installed root and wrote source home/usrname/Downloads/root/bin/thisroot.sh in terminal. it was run.
But i run root again
username@Ubuntu-IP:~$ root
Command 'root' not found, did you mean:
command 'rootv' from deb xawtv (3.106-1)
command 'toot' from deb toot (0.25.2-1)
command 'proot' from deb proot (5.1.0-1.3)
command 'rott' from deb rott (1.1.2+svn287-3)
Try: sudo apt install <deb name>
How do i fix this problem ?
