I am unable to install gnome-tweak-tool in Ubuntu 17.10
ubuntu@ubuntu:~$ sudo apt-get install gnome-tweak-tool

Package gnome-tweak-tool 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
E: Package 'gnome-tweak-tool' has no installation candidate
How can I solve this?
