Install Zabbix 7.2 repo
wget https://repo.zabbix.com/zabbix/7.2/release/debian/pool/main/z/zabbix-release/zabbix-release_latest_7.2+debian12_all.deb
dpkg -i zabbix-release_latest_7.2+debian12_all.deb

Error on this new install, where lsb-release is not installed
apt-get install lsb-release
Try again…
dpkg -i mysql-apt-config_0.8.30-1_all.debError, gnupg not installed
apt install gnupg2
Give it another go…
dpkg -i mysql-apt-config_0.8.30-1_all.deb
I had to list upgradable packages :
apt-list --upgradableWhich spit out : mysql-common/unknown 8.4.4-1debian12 all [upgradable from: 5.8+1.1.0]
Then installed mysql-common
apt-get install mysql-common
Had to uninstall Mariadb to resolve these conflicts
apt remove mariadb-client-coreThen install mysql-server:
apt install mysql-server
Enter your password, twice
Now enter mysql by typing :
mysql -u root -p
Enter the following command individually Where ‘password’ is where you type in your actual own password

zcat /usr/share/zabbix/sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix mysql --u root -p set global log_bin_trust_function_creators = 0; quit;Edit file /etc/zabbix/zabbix_server.conf You can use nano
nano /etc/zabbix/zabbix_server.confUncomment the DBPassword section, and type your password

Screen recording can use webm as their format, it can be more simple to use a gif to embed into a website or forum, than adding scripts to host different video format.
In this case I grabbed a screen record of the progress for writing zeros to a hard drive with dd
Use ffmpeg to convert webm to gif:
First create a pallet:
Move into the directory which the webm is located, or type in the path
Where ‘dd.webm’ is the screen recording
ffmpeg -y -i dd.webm -vf palettegen palette.pngOutput:
Then convert the webm to gif:
ffmpeg -y -i dd.webm -i palette.png -filter_complex paletteuse -r 10 dd.gif
This is what I ended up with, looks like any image of any alien on the interwebz, as if shot through a potato, some tweaking of the command is in my future. None the less.
