====== Devuan APT ======

===== Certificate Error =====

Sometimes, the old certificate will no longer work on secondary packages. In the fall of 2022, we had a problem with goaccess. The way to fix this is to remove the old gpg key, and add a new one from the client site. This will show up when trying to do an //apt update// and will look similar to this:
<code bash>
Err:9 https://deb.goaccess.io focal InRelease
  The following signatures were invalid: EXPKEYSIG 97BD1A0133449C3D Gerardo Orellana <goaccess@prosoftcorp.com>
</code>

Following was the fix for goaccess. Note that the you need to use the correct key to remove, remove the correct file, and download the new file from the correct URL.

<code bash>
apt-key del 97BD1A0133449C3D
rm -rf /usr/share/keyrings/goaccess.gpg
wget -O - https://deb.goaccess.io/gnugpg.key | gpg --dearmor | sudo tee /usr/share/keyrings/goaccess.gpg >/dev/null
cd /usr/share/keyrings
sudo apt-key add goaccess.gpg
</code>

===== Devuan System =====

I have spent significant time trying to figure out what should be the standard apt sources.list files. Finally, I found it (listed right there on the Devuan web site). This is current as of 2021, but go to [[https://www.devuan.org/os/packages]] for the "true" list.

Beowulf
<code bash>
deb http://deb.devuan.org/merged beowulf          main
deb http://deb.devuan.org/merged beowulf-updates  main
deb http://deb.devuan.org/merged beowulf-security main
</code>

ASCII
<code bash>
deb http://deb.devuan.org/merged ascii          main
deb http://deb.devuan.org/merged ascii-updates  main
deb http://deb.devuan.org/merged ascii-security main
</code>

Jessie
<code bash>
deb http://archive.devuan.org/merged jessie          main
deb http://archive.devuan.org/merged jessie-updates  main
deb http://archive.devuan.org/merged jessie-security main

===== Zabbix =====

Same thing for Zabbix. It is sitting somewhere out there on the zabbix web site, but [[https://tecadmin.net/install-zabbix-agent-on-debian/]] has it also.

<code bash>
