On Kubuntu 19.04 I'm trying to install f.lux, but I'm missing python-gconf dependency. When I try to install it, the terminal says:
Package python-gconf 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 'python-gconf' has no installation candidate
You can install
python-gconf
manually from cosmic repository:(usually this method is not recommended, but we do not have other methods)
