I want to update my Tor server, so I did it like this:
sudo apt-get update
sudo apt-get upgrade tor
Output:
tor is already the newest version (0.2.9.14-1ubuntu1~16.04.3).
Now when I go to the Tor metrics details page, I get an input anyway:
This relay is running a version of Tor that is too old and may be missing important security fixes. If this is your relay, you should update it as soon as possible.
How can I update my tor server?
tor
mentioned appears to be correct for 16.04 (https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=tor) so you're using 2016-April software with security patches only backported to them. If you need a later version, you could upgrade to something more modern, or look for other sources (PPA etc) – guiverc Feb 26 '20 at 23:11
