Unable to install curl on Debian

linux debian curl

The libcurl3-gnutls (= 7.47.0-1) package come from testing and it is installed ,to fix curl's dependencies you need to downgrade libcurl3-gnutls version from 7.47 to 7.38 using aptitude (because it's more helpful than apt-get) .

Open the terminal and type the following command :

sudo aptitude -f install libcurl3-gnutls

Follow the instructions and choose to downgrade the package.

I am trying to install Curl on Debian but unfortunately I get the following error:

The following packages have unmet dependencies: curl : Depends: libcurl3-gnutls (= 7.47.0-1) but 7.38.0-4+deb8u2 is to be installed E: Unable to correct problems, you have held broken packages.

I tried to solve that by using: sudo apt-get autoremove as another thread suggested it but I keep having the same issue.

How can I solve that ?

Edit:

Here's the output of apt-cache policy:

Could you edit your question to include the output of apt-cache policy?

Please add the output of cat /etc/apt/sources.list too.

Thanks for your answer GAD3R ! Aptitude didn't gave me the option to just downgrade libcurl3-gnutls so i deleted it with sudo apt-get remove libcurl3-gnutls and then I installed the version needed by curl (7.38.0-4+deb8u3).
