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.

Release files

Verify the same release.

These packages are unsigned. Checksums verify file integrity, not publisher identity. Full instructions are included in README-LINUX-<version>.txt. The README and checksum links resolve from the same latest stable release as the application packages.

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.
