I accidentally deleted most of all the .desktop files and xml in the system. Where can i get these back?

If it is a fresh install you could search for them from Ubuntu ISO. Also you could try to recover files or maybe for .desktop regenerate them.

.desktop files are usually on $HOME/.local/share/applications/ and /usr/share/applications/.

To access files from an Ubuntu ISO:

1. Download the Ubuntu ISO of your version (18.10).


2. Mount the ISO either way:
   
   
   
   
   1. If GUI on nautilus right clicking, Archive Mounter.
      
      
      
      
      1. Go to where the ISO is mounted: /run/user/$(id -u)/gvfs/
         
      
      
      
      
   
   
   2. If terminal with gio mount or:
      
      
      
      
      1. Either gnome-disk-image-mounter iso-file.iso or udisksctl loop-setup -r -f iso-file.iso.
      
      
      2. Go to /media/$USER/, enter the according subfolder.
      
      
      
      
   
   
   
   


3. 
   

   Go to casper/ and:

   
   
   

   cp filesystem.squashfs /tmp/  # You'll need 2GB+ space on partition `/`.
   
   cd /tmp/
   
   unsquashfs filesystem.squashfs
   
   

   
   


4. 
   

   Finally search for the files (idem for /usr/share/metainfo):

   
   
   

   find squashfs-root/ -name *.desktop
   
   

   
   

Then clean up

1. 
   udisksctl unmount -b /dev/loop7p1 Or where the iso was mounted
   
   
   
   
   1. Also could gio mount -u /run/user/$(id -u)/gvfs/archive* or with /media/$USER/.
   
   
   
   


2. rm -rf /tmp/squashfs-root/ /tmp/filesystem.squashfs
