On a server I set up a few years ago, typing cat /etc/lsb-release gives me the following result:

DISTRIB_RELEASE=7
DISTRIB_CODENAME=
DISTRIB_DESCRIPTION=

And lsb_release -a displays:

Distributor ID: Debian
Description:    Debian GNU/Linux 9.13 (stretch)
Release:    7
Codename:   stretch

It seems like the system is not very sure whether it is a Debian 9 (Stretch) or Debian 7 (Wheezy). Some packages that should be available with Stretch cannot be found with apt-cache search.

What can I do to fix this?

The /etc/lsb-release file is largely ignored on most modern systems. The usual source of truth would be the information provided by the lsb_release command. However, neither of these have anything at all to do with which packages you see available. That portion is handled exclusively by the apt sources, which can be found in /etc/apt/sources.list and /etc/apt/sources.list.d.

You can start by examining /etc/apt/sources.list and checking which release is being used for new packages. The SourcesList page on the Debian Wiki has more information about the format of that file and how to update it.
