Comment 20 for bug 1750087

As Alexander already said I confirm that in Kubuntu 18.04 and the following version is still there the output of apt policy libreoffice-core:

libreoffice-core:
  Installed: 1:6.0.7-0ubuntu0.18.04.10
  Candidate: 1:6.0.7-0ubuntu0.18.04.10
  Version table:
 *** 1:6.0.7-0ubuntu0.18.04.10 500
        500 http://es.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages
        500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
        100 /var/lib/dpkg/status
     1:6.0.3-0ubuntu1 500
        500 http://es.archive.ubuntu.com/ubuntu bionic/main amd64 Packages

In my case the sudo apparmor_parser -R /etc/apparmor.d/usr.lib.libreoffice.program.*

disprove the situation, since when I try to save a file, I get a lot of errors about not finding the apparmor profile and then whenever I try to type a name the first character I press gets repeated indefinitely and then Libreoffice crashes.
