```auto
unknown system user 'matrix-synapse' in statoverride file; the system user got removed
```
hmpf i think i saw this bug a few times before in other context, i think it’s debian’s package system somehow derping …
Do you get exactly the same error if you retry ?

Does `sudo id matrix-synapse` return anything ?

(In fact I’m kinda puzzled that the message is about synapse somehow, but we’re trying to install dendrite x\_X)

it gives me this:
```auto
~$ sudo id matrix-synapse
id: ‘matrix-synapse’: no such user
```
i had synapse before, which i uninstalled to then install dendrite.
something when wrong during one of these passages perhaps?

This thread suggest that you can run
```auto
sudo nano /var/lib/dpkg/statoverride
```
and remove the file related to matrix-synapse (and blank lines)
