I can't say for sure since it depends on what is in that file you're
sourcing, but nothing in your command seems obviously incorrect.

The main way to troubleshoot with this kind of situation is:

* Use fab --show=debug (or in-code, wrap the sudo call in a `with
show('debug'):` block). This will make Fabric print out the full,
unabridged command it is sending down the line, eg "sudo -flags
/bin/bash -l -c 'command here'".
* Then try running that command by hand against your server via normal
SSH: "ssh -T hostname <paste fabric full command here>". (The -T is
like Fabric's pty=False.) See how it behaves/runs.

If it works fine via ssh but not via Fabric, then please pastebin the
output of what you tried above (and if possible, the contents of that
complete_environment file) and maybe something will jump out at us.

If it hangs/pauses via ssh too, then it's something in your remote
command that is never exiting, and you'll need to figure out what that
is.

Good luck,
Jeff
