• Edi installation method: ppa
• Ansible installation method: OS package
• LXD installation method: OS package

Desired Behaviour

edi shall not reveal passwords encoded into the proxy url when building a container using 'edi -v ...'

Actual Behaviour (Bug report only)

edi shows passwords encoded into the proxy url within verbose output. This is especially undesired behavior when edi is run on a build server and logs are available for a big audience.

Hints:

• use urlparse to disassemble proxy url
• make sure that the output of the printenv command can be suppressed
