How to Install Remmina on Ubuntu 26.04 – Complete Guide

Configure secure remote desktop connections on your Ubuntu machine. Fix missing RDP options, resolve Snap sandboxing restrictions, and establish stable connections to Windows 11 hosts.

Remmina Installation Methods Compared

Review the installation options below to understand security, package sources, update frequency, and sandboxing details.

If you are running Ubuntu 26.04, skip this step. If you are on Ubuntu 24.04 or 22.04, add the official developer PPA to your system configuration:

sudo add-apt-repository ppa:remmina-ppa-team/remmina-next -y

Update your APT database to scan the newly added repository strings:

sudo apt update

To avoid missing connection protocol options, install the base Remmina package alongside the required plugins for RDP connection support, VNC rendering, and secure secret storage:

sudo apt install remmina remmina-plugin-rdp remmina-plugin-vnc remmina-plugin-secret -y

Tip: You can search for other protocols (like SPICE or EXEC) using the command apt-cache search remmina-plugin.

Execute the snap install command to retrieve and set up the stable channel package:

sudo snap install remmina

Allow the sandboxed application to interact with your host system services by executing the following interface mapping scripts:

# Enable local audio playback
sudo snap connect remmina:audio-playback :audio-playback

# Enable local audio recording (Microphone pass-through)
sudo snap connect remmina:audio-record :audio-record

# Access secure desktop keyring storage for saved passwords
sudo snap connect remmina:password-manager-service :password-manager-service

# Allow document forwarding to local printers
sudo snap connect remmina:cups-control :cups-control

# Enable automatic server discovery via local network scans
sudo snap connect remmina:avahi-observe :avahi-observe

Verify connected plugs using the status check tool: snap connections remmina.

If Flatpak is not already configured on your system, install it using APT:

sudo apt install flatpak -y

Configure the system-level remote pointer to the Flathub catalog:

sudo flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo

Install the containerized package from the repository remote:

flatpak install flathub org.remmina.Remmina -y

Tip: To run the application from the command line, use flatpak run org.remmina.Remmina.

1. Basic Profile Options:

Open Remmina, click the Create a new connection profile icon (represented by a green plus sign), and configure the Basic tab:

• Protocol: Select RDP – Remote Desktop Protocol.
• Server: Enter the target IP address or hostname of the remote Windows computer.
• Username / Password: Provide the credentials of the Windows account. If connecting to a Microsoft/Azure AD account, enter the full login email.

2. Advanced Security Configurations:

Click the Advanced tab located at the top of the profile editor and update the security protocol to match Windows 11’s default requirements:

• Locate the Security protocol negotiation field.
• Change the selection from default to Negotiate or TLS (do not select RDP). Negotiate is the most robust option, as it allows FreeRDP to establish secure handshakes automatically.

3. Resolving Clipboard Sync and Audio Issues:

To pass system audio and sync your local clipboard data with the remote host:

• Ensure Disable clipboard sync is unchecked on the Advanced settings tab.
• Find the Audio output drop-down menu, and select Local to play Windows sound streams on your local Ubuntu speakers.

Click Save and Connect to initiate the remote desktop session.

Example: Migrate Profiles from Snap to Native APT:

Copy your connection configurations to your user folder directory, ensuring you create the destination folder first:

mkdir -p ~/.config/remmina
cp -r ~/snap/remmina/common/.config/remmina/*.pref ~/.config/remmina/

Run the clean script depending on your initial installation setup:

For APT and PPA systems:

sudo apt remove remmina remmina-plugin-* -y
sudo apt autoremove --purge -y

For Snap installations:

sudo snap remove remmina

For Flatpak (Flathub) installations:

flatpak uninstall org.remmina.Remmina -y

If you added the Remmina developer PPA, delete it from your system configuration directory to prevent update warnings:

sudo add-apt-repository --remove ppa:remmina-ppa-team/remmina-next -y
sudo apt update

To delete all saved connection profiles and local configs, execute this command:

rm -rf ~/.config/remmina ~/.local/share/remmina
