Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 3.70 (Debian / Ubuntu)

apt-cache madison video-recording-manager sudo apt install video-recording-manager=<VERSION_BEFORE_3.70> sudo apt-mark hold video-recording-manager
