Using the Debian archive you shouldn't have an apt source line referring to
wheezy-updates. This particular (sub-)distribution is not existing in the archives.
If you just remove the lines:
deb http://security.debian.org/ wheezy/updates main
deb http://ftp.fr.debian.org/debian wheezy-updates main
you should be able to run your
apt-get commands again.
The whole story
wheezy-updates repository contained packages that were provided to update the main repository, i.e.
wheezy, between minor releases. Over time, when Wheezy got updated to 7.1, 7.2 and eventually to 7.11, the packages contained in
wheezy-updates were moved into the main Wheezy repository. When Wheezy got EOLed, in May 2018, no packages were being kept in
wheezy-updates, so there was no point in moving
wheezy-updates to the Debian archive.
You can see the list of all Debian distributions supported by the archive repository at:
http://archive.debian.org/debian/dists/ Also check the README files at http://archive.debian.org/README and http://archive.debian.org/debian/README to have an even fuller list of the archive content.
With regards to the
security.debian.org repository, it is archived as well at http://archive.debian.org/debian-security/ If you want to fetch the very last updates, dating from May 2018, that were published for Wheezy, you can also add this line to your apt sources:
deb http://archive.debian.org/debian-security/ wheezy/updates main
Like said in the comments to your question, be careful when running a machine using the Debian archive as those packages are not updated and so not secure anymore (even when using debian-security from the archive). It probably is OK if your machine is not directly connected to a network, but otherwise, I would highly recommend upgrading as soon as possible.
