Try as I might, I cannot successfully install Parallel Tools in my Debian 11 guest VM. I can mount and access the installation files, but the install process fails with the results entered into the log. It appears that it has to do with running the make command. In this particular scenario, I am using a 2010 MacBook Pro, running macOS High Sierra (10.13.6). I am using Parallels 14.1.3 (45485) with a Debian 11 VM. There was no issues creating the VM, just cannot successfully install Parallels Tools. I obtained the Debian ISO directly from the Debian site and used that to create the VM. When running the VM, I can mount the Parallels Tools, but when attempting to run it, I am greeted with permissions errors. To get around them, I copied the files to a folder on the Linux VM, and then, used: sudo chmod 777 <folder name> -R to gain read/write access to it & its contents. That allowed me to use the: sudo ./install command to the start the installation process ... but again, it fails.
