I am trying to install Perl module on Ubuntu 18.04 / Kamailio kamailio-5.1.6 and getting the following response: $ sudo apt-get install kamailio-perl-modules Reading package lists... Done Building dependency tree Reading state information... Done kamailio-perl-modules is already the newest version (5.1.2-1ubuntu2). You might want to run 'apt --fix-broken install' to correct these. The following packages have unmet dependencies: kamailio-perl-modules : Depends: kamailio (= 5.1.2-1ubuntu2) but it is not installable E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution). Is there a better way to add perl module? PS: libperl-dev already installed. Thanks, AL
