Assuming you installed it with the package manger -
sudo apt-get update
sudo apt-get upgrade

Thank you @ChileBob Bob and @Shawn !!!
Edit: I am trying both recommendations and am getting this:
Messages:
- Error: This version has been deprecated as of block height 476012. You should
upgrade to the latest version of Zcash.
Any suggestions? (NB: I’m not an experienced Linux user :/)

I’m gonna bump this up since I added more to my last comment 🙂

How did you install?
Assuming you’ve upgraded you would need to restart `zcashd` so `zcash-cli stop` followed by `zcashd --daemon` (you might want to look at the `history` command to see if you specified any other options when you started up last time - or run `history | grep zcashd` to show just `zcashd` related commands you previously issued)

You might have installed it with the package manager last time which would have put it on your search path, so when you run ‘zcashd’ its starting that.
Type ‘which zcashd’ to confirm.
If you’ve installed the new version in a different place, try
cd /wherever/you/installed
./zcashd

I know I type `cd ~/.zcash` when I am in the terminal to start the “zcashd” program. I run the zcashd when I am in the path reference above.

Hmm…ok…that might be the problem.
Try running with ./zcashd
That forces it to run the version in the current directory, if you run it without the ./ it’ll run the one the package manager installed.

If I run `zcashd --daemon` I get this:
```
dsd@dsd-System-Product-Name:~/.zcash$ zcashd --daemon
Zcash server starting
dsd@dsd-System-Product-Name:~/.zcash$ Error: This version has been deprecated as of block height 476012. You should upgrade to the latest version of Zcash.
```
I entered “which zcashd” and it tells me “/usr/bin/zcash”
The terminal command line functions in Linux are a mystery to me. I change to the “zcash” path from the root and then try typing “./zcashd” and get an error saying it’s not a valid file or dir. I’m really in the dark ☹
I’m also trying to run `sudo apt-get update` and get this error:
```

Ok - so the version you’re running was installed by the package manager but the upgrade is failing because the gpg key cant be verified.
Here’s instructions on how to fix that - basically deletes the old key, installs the new one & then upgrades with the package manager -

Thanks again 🙂 Sorry for appearing obtuse…I’m not sure how to do this command:
wget -qO - [https://apt.z.cash/zcash.asc](https://apt.z.cash/zcash.asc) | sudo apt-key add -
`Key fingerprint = 3FE6 3B67 F85E A808 DE9B 880E 6DEF 3BAF 2727 66C0`
this linux terminal commands are a mystery…and the zcash page there showing what to do isn’t helpful for n00b users like me 🚼
Does it pull the key from the site and the hash is for reference to make sure it’s legit? after I enter the wget command I get this:
```
dsd@dsd-System-Product-Name:~/.zcash$ Key fingerprint = 3FE6 3B67 F85E A808 DE9B 880E 6DEF 3BAF 2727 66C0
Command 'Key' not found, did you mean:
command 'key' from deb donkey
Try: sudo apt install
dsd@dsd-System-Product-Name:~/.zcash$
dsd@dsd-System-Product-Name:~/.zcash$
dsd@dsd-System-Product-Name:~/.zcash$ wget -qO - https://apt.z.cash/zcash.asc | sudo apt-key add -
OK
dsd@dsd-System-Product-Name:~/.zcash$
```
ok…so now it says ok…I will do more…

…you’ll probably want to upgrade it again now 2.0.3 has been released - it’ll be easier this time now your package manager has been unscrewed. Commands are :-
zcash-cli stop
apt-get update
apt-get upgrade
zcashd -daemon
