turnserver not found in /etc/bin - coturn 4.4.2.1-1

As far as I know, the binaries should be in the /usr/bin directory, not in /etc/bin

Please provide the output of the following diagnostic commands:

uname -a
lsb_release -crid
apt-cache policy coturn
dpkg -l coturn
ls -l /usr/bin/turn*

Did I miss something?

Then it's present. The ls command has unearthed

/usr/bin/turnserver

...?

find /usr/bin/ -name 'turnserver'
/usr/bin/turnserver

Yes, it is there.

Is this indicating I need to reinstall or other? If so please advise step by step action to take.

Please provide also link to configuration commands etc. Thanks.

Thanks actionparsnip, that solved my question.

Thank you all for your assistance.
