Installation Frappe Issues

Dear friends,

~$ sudo bash --setup-production
Installing for Ubuntu trusty amd64
In case you encounter an error, you can post on

Adding ubuntu mariadb repo
Reading package lists…
Building dependency tree…
Reading state information…
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:

E: Package ‘python-software-properties’ has no installation candidate

Can you give me instructions what to do…

I hope this will help you

Thanks for your reply!
Unfortunately, It’s not helping. I have software-properties-common, but it still says that there is no candidate for python-software-properties and I cannot install frappe…

Thanks to everybody involved. the issue was solved by making some right configures in ubuntu’s Software & Updates [put ticks ]
