[tor-relays] Question

[Rubles]

I tried running a bridge but my systemLog said:

Please upgrade! This version of Tor (0.3.2.10) is not recommended, 
according to the directory authorities. Recommended versions are: 
0.2.9.15,0.2.9.16,0.2.9.17,0.3.5.8,0.4.0.5,0.4.0.6,0.4.1.2-alpha,0.4.1.3-alpha,0.4.1.4-rc,0.4.1.5,0.4.1.6,0.4.1.7,0.4.2.1-alpha,0.4.2.2-alpha,0.4.2.3-alpha

(I used sudo apt-get install tor - on Mint) so I checked out 
https://support.torproject.org/apt/tor-deb-repo/ and when I tried gpg 
--export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | apt-key add - it 
didn't work as it said gpg: WARNING: unsafe ownership on homedir
  gpg: [stdout]: write error: Broken pipe
gpg: build_packet(2) failed: Broken pipe
gpg: key export failed: Broken pipe

Here are some other things it said:

Looks like client functionality is working.
Bootstrapped 100%: Done

Your server has not managed to confirm that its ORPort is reachable. 
Relays do not publish descriptors until their ORPort and DirPort are 
reachable. Please check your firewalls, ports, address, /etc/hosts file, 
etc.

What do I do?
