Linux amd64 / Three reliable moves
Download. Verify. Install cleanly.
The current beta is a direct-download .deb rather than a repository package. Keep the package manager in charge of installation so dependencies and future removal remain predictable.
Download only from PractiPix and verify SHA-256 1125ae21172ba15cf613fc438350bd5d862ac81fd0b1a8701683b0dddce0ca8e. If it differs, do not install the package; delete it and download a fresh copy.

Download the Linux amd64 beta package
Open the PractiPix Download page on the Linux computer and choose the Linux amd64 beta. Save PractiPix-1.0.841-Linux.deb, approximately 85 MB.
This build is for 64-bit Intel and AMD systems. In a terminal, run dpkg --print-architecture; the expected result is amd64.
Use only the package delivered by the official PractiPix website and leave it in Downloads until verification is complete.

Compare the package checksum before installing
Open a terminal and run sha256sum ~/Downloads/PractiPix-1.0.841-Linux.deb.
The result must be 1125ae21172ba15cf613fc438350bd5d862ac81fd0b1a8701683b0dddce0ca8e. Every character must match.
If the result differs, do not install the package. Delete it, download a new copy from PractiPix, and contact support if the mismatch remains.
If Downloads is elsewhereType sha256sum followed by a space, drag the downloaded DEB into the terminal window when your desktop supports it, then press Enter.

03Install
Let APT install PractiPix and its dependencies
On Debian, Ubuntu, and compatible distributions, run cd ~/Downloads followed by sudo apt install ./PractiPix-1.0.841-Linux.deb. The ./ tells APT to install the local package while still resolving required dependencies.
Review the package name and disk-space summary, then confirm the installation. Open PractiPix from the desktop application menu when APT finishes.
To remove this beta later while keeping package management consistent, run sudo apt remove practipix. If installation fails, keep the complete terminal output for support.
Graphical installer optionMany Debian and Ubuntu desktops can open the DEB in Software Install or App Center. The terminal route is preferred for beta testing because it keeps dependency errors visible.
