   I just modified the list of sources in /etc/apt/sources.list and /etc/apt/   
   sources.list.d/debian.sources and tried to upgrade from bullseye to trixie    
   directly, but this failed. Maybe this was not a good idea.   
      
   At least the machine boots and runs properly, but no further update    
   possible. - Is there a way to revert back and first upgrade to bookworm    
   and then to trixie, or is the only proper solution to set up a new    
   install?   
      
   Thanks!
