Please stop bouncing the bug. You are free to add bug tasks for packages
that miss necessary AppStream metadata. A return of sessioninstaller is
_not_ acceptable.

** Package changed: sessioninstaller (Ubuntu) => librecad (Ubuntu)

** No longer affects: ubuntu-mate-meta (Ubuntu)

** No longer affects: ubuntu-mate

Title:
  Without sessioninstaller (org.freedesktop.PackageKit dbus service
  provider) user is unable to install applications to handle unknown
  filetypes

Status in Session Installer:
  Invalid
Status in Ubuntu MATE:
  New
Status in librecad package in Ubuntu:
  Confirmed

Bug description:
  Steps to reproduce:
  1. Have Ubuntu MATE 20.04 LTS (or newer) installed
  2. Obtain some file which is unknown for your system (for example DXF)
  3. Open Caja, navigate to this file, try to open it
  4. Caja opens the dialog with text:

      Could not display "/home/user/file.dxf"

      There is no application installed for DXF vector image files.
      Do you want to search for an application to open this file?

    User click 'Yes'

  Expected results:
  * software installation dialog is opened, DXF file will be associated with LibreCAD and opened in it

  Actual results:
  * no dialog is opened after clicking on 'Yes' button

  Notes:

  1. `dbus-monitor` says the following after click on 'Yes':

  2. This problem does not exist in Ubuntu MATE 18.04 LTS. Someone with big competences have removed the sessioninstaller package from Debian as per https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=755504 .
  3. The problem may be fixed as simple as 

     cd /tmp
     wget -c http://archive.ubuntu.com/ubuntu/pool/universe/s/sessioninstaller/sessioninstaller_0.20+bzr150-0ubuntu4.1_all.deb
     sudo apt-get install /tmp/sessioninstaller_0.20+bzr150-0ubuntu4.1_all.deb

  So my verdict is that sessioninstaller package should be reintroduced
  in Ubuntu as soon as possible!
