 It can be worked around by changing the username to `synapse`, for example by using `sed`:
 
 ```Shell
-$ sed -i "s/synapse_user/synapse/g" homeserver.sql"
+$ sed -i "s/synapse_user/synapse/g" homeserver.sql
 ```
 
 This uses sed to perform an 'in-place' (`-i`) replacement globally (`/g`), searching for `synapse user` and replacing with `synapse` (`s/synapse_user/synapse`). If your database username was different, change `synapse_user` to that username instead.

   - **CentOS** (7 only for now; [8 is not yet supported](https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/300))

 Generally, newer is better. We only strive to support released stable versions of distributions, not betas or pre-releases. This playbook can take over your whole server or co-exist with other services that you have there.
