cannot install docker

[Stan Schymanski]

Dear all (sorry for double-posting in case my previous email got through),

I am trying to install the newest docker engine, following the debian 
instructions here: 
https://docs.docker.com/engine/installation/linux/ubuntu/#install-using-the-repository

However, when I try to add the repository:

sudo add-apt-repository \ "deb [arch=amd64] 
https://download.docker.com/linux/debian \ $(lsb_release -cs) \ stable"

I get the following error message:

$ sudo add-apt-repository "deb [arch=amd64] 
https://download.docker.com/linux/debian \
    jessie \
    stable"
Traceback (most recent call last):
   File "/usr/bin/add-apt-repository", line 167, in <module>
     sp = SoftwareProperties(options=options)
   File 
"/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", 
line 105, in __init__
     self.reload_sourceslist()
   File 
"/usr/lib/python3/dist-packages/softwareproperties/SoftwareProperties.py", 
line 595, in reload_sourceslist
     self.distro.get_sources(self.sourceslist)
   File "/usr/lib/python3/dist-packages/aptsources/distro.py", line 89, 
in get_sources
     (self.id, self.codename))
aptsources.distro.NoDistroTemplateException: Error: could not find a 
distribution template for Progress Linux/cairon-backports

I think the program expects something like "jessy" but finds "Progress 
Linux". Is there an easy way around? Thanks a lot!

Best regards,

Stan
