Hi there,
I am new and I tried to solve it by myself and failed. I followed the offical installation guide (Install and Deploy - Linux | Bitwarden Help Center) on a fresh Debian installation. When I try to start bitwarden I get the following output:
bitwarden.sh version 2023.4.3
Docker version 23.0.6, build ef23cbc
Docker Compose version v2.17.3

Error response from daemon: manifest for bitwarden/web:2023.4.1 not found: manifest unknown: manifest unknown
docker ps shows no running containers
Can someone point me in the right direction? The only thing I didn’t do was adding some DNS, because I don’t mind bitwarden being availabale under my original Server adress myvserver.myhost.com - so I just let bitwarden know that this is his new FQDN. I also changed SSL Port to 10001 and opened it. No clue where I went wrong. 
Sorry, I know newbies are a pain in the … but I failed to solve this by myself.
