You can use strace on a specific pid to figure out what a specific process is doing, e.g.:
strace -fp <pid>
You might see something like:
select(9, [3 5 8], [], [], {0, 999999}) = 0 (Timeout)

This gist demonstrates a bug in Go's archive/tar
handling of tar files.
Under certain conditions, tar files generated with Go 1.7 and before cannot
be correctly read with Go 1.8+. While first encountered in Docker, which makes
heavy use of tar files, this gist attempts to make a minimal reproduction
without the Docker code base.
To reproduce this, you'll need respective versions of Go installed in /usr/local/go1.7.6 and /usr/local/go1.8.3. Other methods of version
Here we create the master key. We want only Certify
capability: we use the master key only to create the subkeys, Sign - Encrypt - Authenticate
capabilities will be assigned to the subkeys.
Run the following command to start the master key generation process. Select the set your own capabilities
