Installation problem on Ubuntu under Windows

[Rocket44au]

In the command: bash install-deps
I got the following error message:

Package python-software-properties is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
software-properties-common

E: Package 'python-software-properties' has no installation candidate

I tried replacing python-software-properties with
software-properties-common in install-deps,
but this made no difference.

I found python-software-properties on the Ubuntu site,
but there is no documentation on how or where to install it.

Can anybody help?

There are more than one 'python-software-properties'. Did you replace all of them?
