 I realise this is a repeat ticket, but I still don't know what to do.

 {{{#!python
   sudo port selfupdate
   }}}


 returns the error:

 {{{#!python
 --->  Updating MacPorts base sources using rsync
 Error: Failed to verify signature for MacPorts source!
 Please run `port -v selfupdate' for details.
 Error: /opt/local/bin/port: port selfupdate failed: Failed to verify
 signature for MacPorts source!
   }}}

 So, I try

 {{{#!python
 sudo port -v selfupdate
  }}}

 This outputs

 {{{#!python

  }}}

 and

 {{{#!python
 sudo port -d selfupdate
  }}}

 will output

 {{{#!python
