Onlyoffice Installation Failed

[Dmitry]

Hello, could you specify the exact version of Debian, is it 11.3? We found out that this issue is also present on Debian systems:

Install Workspace on Debian with packages with external DB and Mailserver

Hi Marius, There are multiple configs where you need to set up database connection, and it has to be done manually. Moreover, all configs will be overwritten during updates so I would not recommend changing them. The easiest way for a package installation is to just have a local database instance that is installed by the script. As for mail, if you already have a mail server of your own, you don’t need to install our mail server. Just connect your mailboxes to the Mail module of the portal.

We advise waiting a couple of days until Community Server 12 comes out as the issue is not reproduced on it.
