Linux

Lokus supports Ubuntu 20.04+, Fedora 38+, Arch, and most modern distributions with GTK 3 and WebKitGTK 4.1.

Package formats

DEB (Ubuntu / Debian)

sudo dpkg -i lokus_x.x.x_amd64.deb
sudo apt-get install -f   # fix missing dependencies if needed

RPM (Fedora / RHEL)

sudo dnf install lokus-x.x.x-1.x86_64.rpm

AppImage

chmod +x Lokus_x.x.x_amd64.AppImage
./Lokus_x.x.x_amd64.AppImage

AppImage requires FUSE. If the AppImage fails to start:

# Ubuntu/Debian
sudo apt-get install fuse libfuse2

Dependencies

Most distributions ship these pre-installed. If Lokus fails to launch, install them manually:

Ubuntu / Debian:

sudo apt-get install libgtk-3-0 libwebkit2gtk-4.1-0 libayatana-appindicator3-1

Fedora:

sudo dnf install gtk3 webkit2gtk4.1 libappindicator-gtk3

Arch:

sudo pacman -S gtk3 webkit2gtk-4.1 libappindicator-gtk3

Desktop environment support

Lokus detects your desktop environment (XDG_CURRENT_DESKTOP) and adapts file-manager integration accordingly:

Desktop	File manager	Detection
GNOME	Nautilus	nautilus command
KDE	Dolphin	dolphin command
Xfce	Thunar	thunar command
Other	xdg-open	Fallback

“Reveal in file manager” and similar features use the appropriate tool for your environment.

Auto-updates

The updater checks https://config.lokusmd.com/api/updates/latest.json for new releases. Update signatures are verified against a public key embedded in the binary.
