Prerequisites:

  • Due to the slicer being built on CentOS 7 it picks up a new library dependency on libnl-3.200, which is not included in the base install of Ubuntu 18.04. You may need to pre-install it: sudo apt install libnl-3-200

  • Nvidia driver 418 or later is required for HEVC 4K HDR/SDR.

  • Due to CentOS 6 reaching EOL in November 2020 this slicer release requires CentOS 7 or newer.
