    You can use 7z also to extract the contents of the archive : 7z e plugin\:monitor-v1.2-1.tgz Sep 3, 2019 at 10:41

Because of the : in the archive filename, tar thinks you are trying to extract an archive on a remote system - hence the message:

cannot connect to plugin: resolve failed

You can force it to treat the file as local by adding the --force-local option. From man tar:

          Archive file is local even if it has a colon.

Allways use tab to complete names in linux, if you do that, you can see that will be like this:

tar -xvzf plugin\:monitor-v1.2-1.tgz
