What is the problem?
Can't install plugins from the menus.
What did you already try to solve it?
Reviewed the logs, however, confused by what it wants.
Logs (octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)

CalledProcessError: Command '('lsb_release', '-a')' returned non-zero exit status 1
I'm going to take an educated guess and say the installation has filesystem issues or there is something broken with the installation itself.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Got this: when typed it at a command prompt
Traceback (most recent call last):

              Could it be an issue with having python 2.7 and 3.7 on the rpi4.
             
            
              
              
              
            
            
                
                
              
           
          
            
            
              Shouldn't be. Would just make a backup of the pi home dir and reflash.
