Debian binary packages setup

The Electric Coin Company operates a package repository for 64-bit Debian-based distributions. If you'd like to try out the binary packages, you can set it up on your system and install Zallet from there.

First install the following dependency so you can talk to our repository using HTTPS:

sudo apt-get update && sudo apt-get install apt-transport-https wget gnupg2

Next add the Zcash master signing key to apt's trusted keyring:

wget -qO - https://apt.z.cash/zcash.asc | gpg --import
gpg --export B1C9095EAA1848DBB54D9DDA1D05FDC66B372CFE | sudo apt-key add -

Key fingerprint = B1C9 095E AA18 48DB B54D 9DDA 1D05 FDC6 6B37 2CFE

Add the repository to your Bullseye sources:

echo "deb [arch=amd64] https://apt.z.cash/ bullseye main" | sudo tee /etc/apt/sources.list.d/zcash.list

Or add the repository to your Bookworm sources:

echo "deb [arch=amd64] https://apt.z.cash/ bookworm main" | sudo tee /etc/apt/sources.list.d/zcash.list

Update the cache of sources and install Zcash:

sudo apt update && sudo apt install zallet

Troubleshooting
