Could not create file /var/log/tinyproxy/tinyproxy.log: Permission denied

[proofer]

Version 1.11.0 installed yesterday from ubuntu package
Yesterday:

sudo tinyproxy -d
tinyproxy: Could not create listening sockets.

--although ss showed no other process using 8888.
I saw another Issues report of this problem that was fixed by changing tinyproxy's Port. But it was time to leave it for the night.

This morning, after rebooting, instead of the previous error, I got:

sudo tinyproxy -d
tinyproxy: Could not create file /var/log/tinyproxy/tinyproxy.log: Permission denied
^C

.conf :
User tinyproxy

don't use sudo. and change your config to use neither pidfile, nor logfile, nor user, nor group, so it runs as your own restricted user.

I had to wait 17 minutes after posting my issue to get a response!

(But seriously: thanks!)
