Can’t extract rar files on Ubuntu?

I’m trying to extract a RAR file (a type of compressed file) on my new Ubuntu machine. I use the built-in archive manager application and keep getting this error message:

screen shot showing the error message "an error occurred while exracting files. Parsing filters is unsupported".






Originally I thought it was a problem with the file (maybe corrupt), but after doing some DuckDuckGo’ing I found a simple cause: unrar (the programme to do the extracting) wasn’t installed!

The solution is to go to the commandline and do:

sudo apt-ger install unrar

a screenshot of my computer display showing the command to install unrar from the commandline





Now, its all working!
