Get version 0.5.0 from the download page. Both platforms are 64-bit.

Download Lantern-Terminal-0.5.0-windows-x64-setup.exe and run it. It installs for your current user under LocalAppData by default and adds a Start menu entry. Start Lantern Terminal from that menu.

For a portable installation, download Lantern-Terminal-0.5.0-windows-x64.zip, extract it and run LanternTerminal/lantern-terminal.exe. Keep the extracted DLLs, plugins and data folders with the executable. The package includes Qt, Python, libssh (the built-in SSH engine), FreeRDP (Remote Desktop) and OpenSSH clients; it does not install an SSH server.

The application targets Windows 10 or later. The installer and raw TCP/scripting workflow have passed Wine checks, but physical Windows ConPTY and device/provider behaviour still need target testing.

On a compatible Debian-based distribution, download lantern-terminal_0.5.0_amd64.deb, open a terminal in that directory and run:

sudo apt install ./lantern-terminal_0.5.0_amd64.deb
lantern-terminal

It also adds an applications-menu entry. The package declares its actual library dependencies. It was built with Qt 6.10.2 and is not compatible with every Debian/Ubuntu release. If apt reports unavailable dependencies, build from source with Qt 6.8 or later and the required modules.

The Linux tar archive uses the same system libraries as the Debian package. Extract it, then run usr/bin/lantern-terminal inside the extracted tree. It is not a self-contained AppImage.

From 0.5.0 on, Lantern tells you when a new version is out and Update Now installs it (Help → Check for Updates… checks at once). To upgrade by hand, close the application when your sessions can safely be disconnected, then install the new package. Windows reinstall/uninstall checks verify that existing profiles are preserved. On Linux, remove the package with sudo apt remove lantern-terminal; on Windows, use Settings → Apps. Back up your configuration before changing computers or upgrading: Help → About Lantern Terminal shows its exact directory.

The Windows portable archive still uses the normal user configuration directory unless launched with –config pointing elsewhere. To try an independent profile on Linux:

lantern-terminal --config "$HOME/lantern-test-profile"

• Saved session is missing: clear the Sessions filter, expand the folder, then use Edit → Go to Session Manager. Check the profile directory in Help → About if you used –config.
• Unreadable interface or wizard: install version 0.3.1 or later and choose Options → Theme → Light (or Dark/System). Changes apply immediately.
• Ctrl+F, Ctrl+Q or Ctrl+N no longer open Find, Exit or New session: since 0.3.2 these keys go to the terminal. Use Ctrl+Shift+F, Ctrl+Shift+Q and Ctrl+Shift+S, or the menus.
• A session says it is using OpenSSH: it uses something the built-in SSH engine does not support yet (X11 or agent forwarding, extra OpenSSH options). That is expected; it connects as before.
• SSH reports it could not open a trace logfile: version 0.3.1 fixes the temporary-file handle conflict on Windows. Upgrade, then reconnect.
• Colours need changing: open Options → Session properties → Terminal → Appearance, then use Choose colour…. Cancel preserves the previous colour.
• No password prompt / Permission denied (publickey): the server accepts SSH keys only. Select the authorised private key under Session properties → Connection → SSH2 → Private key / identity, or use a key in your SSH agent. A server key accepted at first connection only verifies the server identity.
• SSH will not connect: check hostname, port and username. Authentication prompts appear in the terminal. Inspect the reported SSH error and verify server access. SSH passwords are prompted, not saved in this release.
• Python does not launch: Linux needs Python 3; Windows includes its own runtime. Global Settings → Automation can select a different interpreter.
• Older Linux libraries: use the source build instead of installing incompatible binary dependencies.

For reports, include the application version, operating system, protocol and error text. Avoid including passwords, private keys or session logs containing secrets. Contact slaterm@theiguru.au.
