Just to inform that, according to this, by using the following command:
sudo apt update
sudo apt install certbot nginx ffmpeg postgresql postgresql-contrib openssl g++ make redis-server git cron wget
ffmpeg -version # Should be >= 4.1
g++ -v # Should be >= 5.x
redis-server --version # Should be >= 6.x
It can only install Redis server v=6.0.16
Redis server v=6.0.16 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=a3fdef44459b3ad6
Your distro only provides 6.0.16.
The solution to this is to switch to a different distro/version, add unstable/testing packages or manually compile the package.
This is not a peertube issue.
Thanks for your reply and help.
What I meant is, I have followed the official installation guide.
Like you said,
if distro only provides 6.0.16. And after installation, it notifies,Peertube: recommended to use a minimum Redis version of 6.2.0.
In this case, the official docs may need to make a little changes.
I can confirm that it will work with 6.0 (as said in the link given by @vid-bin )
