Trying to upgrade via PPA

Help
1

I am trying to use the following:

sudo add-apt-repository ppa:oisf/suricata-stable

The error says that the cosmic release no longer has a release file.

Is this not supported on Ubuntu 18.04?

2

Bionic(18.04) is supported, Cosmic (18.10) is EoL. Which one is that you are trying to upgrade in?

Here is part of the add repository command output.

What is the output of
lsb_release -a
on the OS that you are trying to install Suricata? (It looks like Cosmic which is EoL)

5

lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.10
Release: 18.10
Codename: cosmic
root@Demo-Development:/sysadm/scripts#

Yes, I will manually install Suricata until I can get the OS up to date. Any good update path forward for EOL product?
