Apt Update Error By Some repos After SdkManager Sdk Installations

After sdk installations by sdkmanager these repos enter to package list and cause error on update.

Do anyone else also experience this?

Hi osmanberkx0x,

The Ubuntu security updates server does not provide arm64. If you browse this you’ll see what is available:
http://security.ubuntu.com/ubuntu/dists/xenial-security/main/
