When trying to install curl on Ubuntu 16.04, it gives me the following error message:
Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: curl : Depends: libcurl3-gnutls (= 7.47.0-1ubuntu2) but 7.47.0-1ubuntu2.6 is to be installed E: Unable to correct problems, you have held broken packages.
How to fix?
