install.sh not asking for administrator password

I managed to forget my admin passwod, so I cant login at the web interface.

No problem, I thought, just uninstalll und re-install the whole thing. I am following Linux Standard Deployment | Bitwarden

However, I am not asked for an admin pw anymore. I recognized no other changes, but this one makes me stucked. I tried twice, second time additionally removing bitwarden/ and database.tgz from /opt/bitwarden.

Any clue what might go wrong ?
Thx, Volker

Just based on my experience with other app installations on Linux, you may need to delete the existing Bitwarden admin account.

It’s quite common for install scripts to create additional accounts and groups. If the the install scripts discovers the accounts and/or groups exist, the script will skip the account creation stage.
