Required Steps for Ubuntu 26.04

• Verify Hardware: Confirm the sensor is the Broadcom 58200 by running lsusb | grep 58200 in the terminal; the ID should be 0a5c:5843.
• Install Legacy Library: Download and install libssl1.1 manually, as it is no longer in the default Ubuntu repositories : shell wget http://nz2.archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb
• Install Driver: Download and install the Broadcom-specific fprint driver: shell wget http://dell.archive.canonical.com/updates/pool/public/libf/libfprint-2-tod1-broadcom/libfprint-2-tod1-broadcom_5.12.018-0ubuntu1~22.04.01_amd64.deb sudo dpkg -i libfprint-2-tod1-broadcom_5.12.018-0ubuntu1~22.04.01_amd64.deb
• Enable Authentication: Restart the fprintd service (sudo systemctl restart fprintd) and enable fingerprint login via sudo pam-auth-update, ensuring Fingerprint authentication is checked. 
• Enroll Fingerprints: Use the terminal command fprintd-enroll to register your fingerprint, as the GUI settings menu may be unreliable for this specific driver. 

Note that because Ubuntu 26.04 is a future release relative to the driver's 22.04 packaging, compatibility is not guaranteed and may require further troubleshooting or community patches.
