Often the problems of the operating system either closed source or open source, often crash, hang, or else there is an error.
And i have problem too, when i will run and update metasploit cli. Following step by step:
1. Open konsole or terminal then type cd /opt/metasploit
2. After entry into metasploit folder, type again with command: git clone https://github.com/rapid7/metasploit-framework.git msf3
3. Wait until process finished
4. Show with list command using “ls -l or ls -a” when finished.
5. Then exit and type command msfupdate and msfconsole
