Installing from COSMIC Flatpak Repository

flatpak remote-add --if-not-exists --user cosmic https://apt.pop-os.org/cosmic/cosmic.flatpakrepo
flatpak install --user io.github.hepp3n.kdeconnect

---

Building from Source

Prerequisites

• rustup.rs
• libxkbcommon-dev (required on some distros — if the build fails, install this first)
• just command runner

Quick Start

git clone https://github.com/hepp3n/kdeconnect.git
cd kdeconnect
just build
just install

The service starts automatically on next login via D-Bus activation and XDG autostart.

Optional: Systemd Integration

For journalctl logging and systemctl control instead of D-Bus activation:

just install-systemd
just enable-service

Note: You may need to log out and back in for the applet to appear in the COSMIC panel. Once logged back in, go to COSMIC Settings → Desktop → Panel → Configure Panel Applets and add KDE Connect.

Debug Install

Full logging for both the service and panel applet:

just install-debug

• Service logs → /tmp/kdeconnect-service.log
• Applet logs → /tmp/kdeconnect-applet.log

Restore to standard install with just install.

---

Uninstalling

just uninstall

---

Building as Flatpak

Requires flatpak-builder:

flatpak-builder --force-clean --user --install-deps-from=flathub --repo=repo --install builddir io.github.hepp3n.kdeconnect.json

Troubleshooting

Some distributions enables Firewall by default. Or you are enabled it by yourself. In this case, check what firewall you are using. And allow 1714-1764 port range for TCP and UDP connections.

For UFW firewall:

sudo ufw allow 1714:1764/udp
sudo ufw allow 1714:1764/tcp
sudo ufw reload

For Firewalld:

sudo firewall-cmd --permanent --zone=home --add-service=kdeconnect
sudo firewall-cmd --reload

For IPTables:

sudo iptables -I INPUT -i <yourinterface> -p udp --dport 1714:1764 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo iptables -I INPUT -i <yourinterface> -p tcp --dport 1714:1764 -m state --state NEW,ESTABLISHED -j ACCEPT

sudo iptables -A OUTPUT -o <yourinterface> -p udp --sport 1714:1764 -m state --state NEW,ESTABLISHED -j ACCEPT
sudo iptables -A OUTPUT -o <yourinterface> -p tcp --sport 1714:1764 -m state --state NEW,ESTABLISHED -j ACCEPT
