[Trisquel-users] Re : How to access encrypted home folder (mounted on separated partition) from another trisquel installation

[lcerf]

Does the system actually let you log in?  Or do you boot into into a root  
terminal (maybe using a recovery mode menu entry you enabled in  
/etc/default/grub)?  Or maybe you use 'chroot' from a live system?

I would try try that command:
# ecryptfs-recover-private /home/li/.Private
