You need to upgrade to the latest released version of zcashd, which is 5.10.0.

@str4d I followed the instructions here to install zcashd on Linux. The version that is installed is 5.9.0. When I run sudo apt-get update && sudo apt-get upgrade zcashd is still 5.9.0. How do I upgrade to 5.10.0?

@metalworker2 Could you please run: apt update and then apt show zcash and paste here the output of the last command ?

Hey, I just wanted to leave a comment and say that I got my lightwallet GUI to work. Once it finished syncing, which took ages, it now shows the number of zec that I have. Thanks for the help!

My new problem is how I can hook up a pricing service to the zcash/jightwallet wallet, to see the value in USD?? I have a USD label showing in the wallet, but there's no price next to it...

@metalworker2 Could you please run: apt update and then apt show zcash and paste here the output of the last command ?

I am also trying to upgrade, but without success. The version still remains 5.8.0

There is some strange behavior here. When I run sudo apt install --only-upgrade zcash it returns:

zcash is already the newest version (5.10.0).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Then when I run zcashd it still says:

Do you know how I can get it to stop running 5.9.0 and run 5.10.0 instead?

Try running this:

$ dpkg -L zcash

You should get something like this:

/.
/usr
/usr/bin
/usr/bin/zcash-cli
/usr/bin/zcash-fetch-params
/usr/bin/zcashd
/usr/bin/zcashd-wallet-tool

/usr/share/man/man1/zcashd.1.gz

Then, identify the zcashd binary, in this example: /usr/bin/zcashd, and run this in your console:

/usr/bin/zcashd --version

It should say v5.10.0. If you want, paste the output here so we can continue debugging.

Here is the translation:

Try running this:

apt-cache policy

With that, you should see all the repositories configured on your system. If you're using Debian Bookworm, you should get something like this:

 500 https://apt.z.cash bookworm/main amd64 Packages
     release o=. bookworm,a=bookworm,n=bookworm,l=. bookworm,c=main,b=amd64

In the case of Bullseye:

 500 https://apt.z.cash bullseye/main amd64 Packages
     release o=. bullseye,a=bullseye,n=bullseye,l=. bullseye,c=main,b=amd64

If Buster appears, you should remove it because we deprecated it.

Once you manage to identify and fix the repositories (you can use this as a guide: https://zcash.readthedocs.io/en/latest/rtd_pages/install_debian_bin_packages.html),

you should run apt update and then apt upgrade zcash.

What are the outputs of the following two commands?

which zcashd
dpkg -S `which zcashd`

Try running this:
apt-cache policy

I have Ubuntu, however, there is not a line about zcash. So, no repository is connected?

UPD: Everything worked. After fixing the repository, the zcash update came along with other OS updates. Thank you.

The APT system is working fine on your system based on the outputs of your commands. What I can deduce is that you have a different installation of zcashd located in /usr/local/bin/zcashd. I'm not sure if you ever installed it from source code or how your system is configured, but your $PATH variable is likely pointing to /usr/local/bin first, and possibly also to /usr/bin. It's very common to have something like this:

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin

As a result, there's a priority in the order, and it's using the binary from /usr/local/bin/zcashd, which is not the one from the Debian package. That's where the issue lies—it's something in your environment.
