Questions and problems

Nothing happens when I start 2fip

2fip allows one window at a time. If it’s already open (maybe on another workspace or screen), starting it again brings that window to the front. This also counts the Flatpak, the AppImage and a regular install: only one of them runs at a time.

F9 doesn’t open a terminal

2fip uses the terminal chosen in COSMIC Settings, then $TERMINAL, then x-terminal-emulator, xdg-terminal-exec and common terminals (COSMIC Terminal, GNOME Console and Terminal, Ptyxis, Konsole, Xfce Terminal, Tilix, Alacritty, Kitty, Foot, xterm…). Install one of them, or set $TERMINAL. Inside a Distrobox container with no terminal, 2fip opens your system’s terminal.

Thumbnails don’t appear

Check that Show thumbnails is on in Settings. 2fip uses the thumbnail programs of your system (for images, PDFs, videos, fonts); install the one for the type you need (for example ffmpegthumbnailer for videos). There are no thumbnails for files on servers.

A server asks for my password every time

Edit the connection in the Connections panel and tick Remember the password in the system keyring. If your system has no keyring service (GNOME Keyring or KWallet), passwords can’t be stored.

“The server’s key has changed”

The server’s SSH key doesn’t match the one in ~/.ssh/known_hosts. If you know the server was reinstalled, remove its old line from that file and connect again; otherwise, don’t connect and ask its administrator.

FTPS says the certificate isn’t valid

2fip only accepts valid certificates (like a browser). Servers with a self-signed certificate can’t be used over FTPS yet; use SFTP if the server offers it.

Where are my settings?

In ~/.config/2fip/: settings.json, favorites.json, connections.json and session.json (the open tabs). Delete a file to reset that part.

The AppImage doesn’t start

It needs glibc 2.39 or newer (Ubuntu / Pop!_OS 24.04, Fedora 40, or later). On older systems, use the Flatpak.
