Package not install after run npm install

Hii all, I clone joplin source code and then run npm install but package is not installed.
Here is my terminal-

root@ bootstrap /home/suman/joplin
lerna bootstrap --force-local --no-ci

lerna notice cli v3.22.1
lerna info versioning independent
lerna info Bootstrapping 16 packages
lerna info Installing external dependencies
The authenticity of host ' (' can't be established.ency 8
RSA key fingerprint is SHA256:nThbg6kXUpJW******
[ ...] / install dependencies: verb installed leaf @joplin/app-desktop

It's been looking like this for 20 minutes..
I try 2-3 times nothing happened all time i stuck at this point.
