The post install config generation instructions ask the user to cd to /var/lib/synapse. This step is unnecessary, and additionally is impossible.

$ cd /var/lib/synapse
cd: permission denied: /var/lib/synapse

$ sudo -u synapse python2 -m \
--server-name \
--config-path /etc/synapse/homeserver.yaml \
--generate-config \
works fine.

Additional info:
Name : matrix-synapse
Version : 0.22.1-2

Turns out it actually is important to run the command with current working directory /var/lib/synapse. It's just inconvenient because of the permissions of that directory and the fact that su synapse fails, since logins are disabled from that account. The easiest thing for me to do was to make this script. Could you consider shipping it with synapse?

The easiest way is to just run that sudo command as root. If you want that script included you're going to have to get it upstreamed

What is your solution exactly? Remember it has to run as synapse in the directory /var/lib/synapse. Have you actually tried it?

Johannes, I'd say the easiest way is to wrap *both* commands in the sudo invocation. But whatever, it (running the whole thing from a root shell) does seem like the kind of obvious thing users should realize.

(Aside: that wrapper script brings me nightmares of `update-grub`.)
