/opt/metasploit/apps/pro/engine/update.rb:62:in `

': undefined method `[]' for nil:NilClass (NoMethodError)



Solution

option 1) run msfupdate again after logging in at https://localhost:3790 with your account and it works

option 2) Another way is to run msfconsole and once the msf shell is ready you enter

msf>sudo msfupdate
