Hello Yan,

I tried to use your script to install YDK 0.8.5, I got this:

Also I have:

updatedb: can not open a temporary file for `/var/lib/mlocate/mlocate.db'
*** Thu Sep 10 18:57:48 CEST 2020 *** install_ydk.sh | Exiting '/nobackup/vadigreg/workspace/ydk-gen/test/dependencies_centos.sh' with status=1 

Not sure if updatedb should be sudo?

Hello Val

I also failed to install YDK on RHEL/CentOS-8.x. That is why it is still listed as not supported. More efforts are needed to make it work. But that work must be done as well as installation on Ubuntu 20.04LTS. If you are lucky to find the way, please share it with the YDK community. Then the procedure could be added to the install_ydk.sh script.

Thanks for the efforts.

I managed to install ydk for python both core and gnmi by removing lcov and python-venv, then I added sudo before updatedb. That was all I had to do.
