Error building dependancies

Hi When I run this command on Ubuntu:
./engine/build/scripts/install_dependencies.sh

I get this error:
E: Package 'libvpx5' has no installation candidate

Also, when I try to build the stereo_dummy sample I get multiple errors like this one:
ERROR: /home/robomike/.cache/bazel/_bazel_robomike/0f4862df8f60ace29048e3f827140f07/external/capnproto/BUILD.bazel:20:11: Compiling c++/src/kj/memory.c++ [for host] failed: undeclared inclusion(s) in rule ‘@capnproto//:kj_lite’:
this rule is missing dependency declarations for the following files included by ‘c++/src/kj/memory.c++’:

How to resolve these errors?

This is because my ubuntu version is 20.04 and Isaac only supports 18.04

Yes, that is correct. Isaac SDK 2020.2 is only supported on Ubuntu 18.04 LTS and JetPack 4.4.1. It is possible to run Isaac SDK development in an 18.04 container, however, while keeping your host machine 20.04 which is my personal workflow.
