@MickLesk I already have Vaultwarden running on my Proxmox. I want to run the script again to install any updates.

please see the complete output i get from the Proxmox console after running the script

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/vaultwarden.sh)"

The output is

Are you sure that you have Debian ? That Looks Like alpine. Can you Hit "apt-get update"?

[achilleus68]

Ok, that is really stupid of me.
Completely missed the OS toggle buttons at the community-scripts page.

You are correct, I have Alpine.

This none-issue can be closed

[MickLesk]

You know thats enough to Hit "update" inside the LXC? You dont need to Copy the bash call

[achilleus68]

You mean apk update. No I did not know that was sufficient. Thanks

[MickLesk]

No "update"

[CerberusStyle]

To update an already installed community script LXC all you have to do it type update nothing more and it will launch the update script.

[achilleus68]

No, did not know that. Just tried it, great feature! Thanks
