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?
