Fail to install Jetpack

Can you please help me with this error when trying to install the Jetpack 4.5.1 and others.

SDK Manager is verifying system readiness to install.
Access to APT repository and ability to install Debian packages with it.
Your system is not ready for install, see specific errors below. Once fixed, click ‘Retry’ to verify system readiness again.
Access to APT repository and ability to install Debian packages with it.: Apt repository check failure (sudo -S apt-get update && sudo -S apt-get check).

Hi vantai,

Are you using standalone Ubuntu18.04 as your host PC?

Does the above error come from your host PC or your board?
Could you help to capture what command you run and what result you get?

Hi Kevin,

I use Ubuntu 18.04 on VMWARE installed on my Windows 10 PC. This error come from the host PC. This error comes after executing sdkmanager and using the software to install Jetpack.

Many thanks.

Van Tai

You could try the following command to add key to trusted set of keys.

$ sudo apt-key adv --keyserver --recv-keys B53DC80D13EDEF05 
$ sudo apt-key adv --keyserver --recv-keys FEEA9169307EA071

SDK Manager is not recommended to run in VM or docker because it might not detect the board and cause Jetpack installation failed.
