Steps to install BlueJeans on Debian

  • Download BlueJeans RPM
  • Install alien package sudo apt-get install alien
  • Convert BlueJeans RPM to a DEB package sudo alien --to-deb --scripts bluejeans-*.rpm
  • Install resulting DEB sudo dpkg -i bluejeans_*.deb
  • Run BlueJeans with /opt/bluejeans/bluejeans-bin

You may get an error loading the expected udev library
