Today, i installed Ubuntu 20.04 LTS on latest virtualbox. everything is fine except fullscreen. I tried to install guest addition by clicking on " Insert guest addition CD image ". At first , it said gcc make perl is not install on your Ubuntu. i checked the installation step of gcc make perlon Ask Ubuntu website and did the same.
But error occurred. i did it (guest addition) manually by the same step written on Ask Ubuntu website but didn't succeed. now , neither terminal-commands works nor "insert guest addition CD image " that is as a option of Devices. What to do now ? i am not pasting the error that comes after clicking insert guest addition CD image in Devices because after so many try, i can't paste. Help me.

Is your host or guest Ubuntu 20.04 LTS? That is not clear from your question.
You might want to follow the documentation on Virtualbox here. Assuming that your guest is Ubuntu 20.04 LTS:
- Make sure that your guest is prepared for building external kernel modules. Refer to this section of documentation.
- Insert the VirtualBox guest additions CD into your Linux guest.
- Run the shell script on the virtual CD by
sh ./VBoxLinuxAdditions.run
