Answer 1

You have several TLS-related libraries in /usr/local/lib, in the normally configured system they should not be here. The APT installs libraries to /lib, /usr/lib and so on.

So you have to move the related libraries to home folder with:

mkdir ~/wrong_libs
sudo mv /usr/local/lib/libgnutls* ~/wrong_libs/
sudo mv /usr/local/lib/libnettle.so.7 ~/wrong_libs/
sudo mv /usr/local/lib/libhogweed.so.5 ~/wrong_libs/

and then all should be fine.
