java - AndroidStudio Project Compilation Error: Can't download gradle 4.1.1 - Unable to find valid certification path to requested target

Question

I'm completely new to programming and just set up AndroidStudio on Ubuntu inside a VirtualMachine.

I set up JDK and SDK, everything went fine - but when I tried to create my first project, the compilation fails immediately (see error message below).

I already tried:

• changing the gradle version in build.gradle
• changed the distributionURl in gradle-wrapper.properties to https://services.gradle.org/distributions/gradle-6.4-all.zip
• exporting and importing the certificates from a browser
• setting 'Accept non-trusted certificates automatically' to true

Error message:

A problem occurred configuring root project 'HelloWorld'.

Could not resolve all artifacts for configuration ':classpath'. Could not resolve com.android.tools.build:gradle:4.1.1.
