[SOLVED] Can't install Parallels tools anymore on Ubuntu 20.04 LTS

Hi,

I am running Parallels 16.1.3 (49160) on an Intel-based Big Sur 11.5.1 machine and my Ubuntu 20.04 LTS guest used to work just fine. Yesterday, I put that virtual machine to sleep and fireing it up this morning, the screen resolution is back to what it used to be before installing Parallels tools.

So, I decided to reinstall Parallels tools, but to no avail. As can be seen from the error log below, the problem is due to TIF_IA32 being undeclared:

Started installation of Parallels Guest Tools version '16.1.3.49160'
Previous version was not found. Nothing to backup.

Has anyone come across this issue? Is there a fix for it?

Cheers, Alan.

 

Ok, thanks to (GalaxyMaster)'s patch and DerekE2's instructions, I was able to reinstall Parallels Tools just fine. Not at all impressed with Parallels though: the community shouldn't have to patch a paid-for product like Parallels. Thanks to (GalaxyMaster) and DerekE2 for your indirect help though. Much appreciated!
