Linux x64 Preview

Choose the Linux package
that fits your system.

Install with a DEB on Ubuntu, Debian, or Mint; use one AppImage on other x64 distributions; or keep the portable archive as a technical fallback.

Install for Ubuntu / DebianDownload AppImage

Linux x64 only · No ARM64, Snap, Flatpak, or RPM package

Recommended for Debian family

Install for Ubuntu / Debian

.deb package · Recommended for Ubuntu, Debian and Mint

  1. Download the DEB.
  2. Double-click the .deb file.
  3. Open it with the software installer or App Center.
  4. Install, then launch ALTARA from the applications menu.

Terminal fallback:

sudo apt install ./<filename>.deb

ALTARA can check and download a newer DEB. Installing it uses the normal system authorization and package-manager flow; it is not a silent update.

Download AppImage

Linux x64 · Single portable application

  1. Download the AppImage.
  2. Open a terminal in the download folder.
  3. Mark it executable and run it:

The packaged AppImage supports ALTARA update checks. Desktop menu integration is not claimed or installed automatically.

Manual updates are required for the portable tar.gz.

Ubuntu dependencies

Ubuntu 24.04 or newer

Ubuntu 22.04

sudo apt update
sudo apt install -y libnss3 libnspr4 libasound2

Package limits

These downloads are Linux x64/amd64 only. ALTARA does not currently ship ARM64, Snap, Flatpak, RPM, or AppImage desktop menu integration.

The DEB integrates with the applications menu. The AppImage stays a single executable file. The tar.gz remains an advanced, manually managed fallback.

Portable troubleshooting

Inspect missing shared libraries:

ldd ./altara-desktop | grep "not found"

Only if chrome-sandbox reports an ownership or permission error:

sudo chown root:root chrome-sandbox
sudo chmod 4755 chrome-sandbox

Do not use --no-sandbox as the normal workaround.
