Client Out Of Date

Technical Support
1

Returning to Zcash after a period of inactivity when I run ./src/zcash-cli getinfo I get the following message:

Your client is out of date and potentially vulnerable to blockchain disruption. Please update to the most recent version of Zcash and use -reindex to ensure integrity of your blockchain state. More info at: Security Information - Zcash

As I’m running Ubuntu I use the following to try and update my Zcash, based on the Debian guide:

sudo apt-get install apt-transport-https
wget -qO - https://apt.z.cash/zcash.asc | sudo apt-key add -
echo "deb [arch=amd64] https://apt.z.cash/ jessie main" | sudo tee /etc/apt/sources.list.d/zcash.list
sudo apt-get update && sudo apt-get install zcash

However after a reboot I still get the same error message. I have no idea how to perform a -reindex :frowning:

Grateful for any help.

Someone (in dev team) helps us please…

the above is trying to get an already built ver from the repository, but it may be old - not updated.

did you try manually building it from the source?

OK, thanks, I followed the instructions at juhub’s linked page, namely:

git fetch origin
git checkout v1.0.10-1
./zcutil/fetch-params.sh
./zcutil/build.sh --disable-rust -j$(nproc)

and this worked. I guess I had been put off doing this by the preceding statement which said If you're on a Debian-based distribution, you can follow the Debian instructions to install zcash on your system.

Appreciate your help…
