in Kali Launcher --> Update Kali chroot, everything is OK, except postgresql and metasploit
At first, it says directory "/var/lib/postgresql/9.1/main" has group or world access, permissions should be u=rwx.
Then I change the permission to 700: chmod -R 700 main, still fail. It says: /usr/lib/postgresql/9.1/bin/pg_ctl start ... FAIL!!
What's the problem? Anyone knows?
