Attempts to use LibreOffice help give an "object not accessible" dialogue

Using LibreOffice version 6.4.3.2 on Ubuntu 20.04. I have purged and then reinstalled LibreOffice, but it still behaves the same.

Hello,

this is a messed initial install of LibreOffice on Ubuntu 20.04 and for an unknown reason LibreOffice tries to call the old, deprecated help viewer instead of the default browser - the following procedure fixed that on my system (and others reported this also worked for them)

Completely remove anything related to LibreOffice

  • dpkg --list | awk '/ii/&&/libreoffice/{print $2}' | sudo xargs apt purge -y ure
  • sudo apt autoremove -y
  • sudo rm -r /usr/lib/libreoffice/*

Reinstall

  • sudo apt install libreoffice (you may need to reinstall the offline help package as well, but can’t provide the correct package here, since you did not provide your Help -> About LibreOffice information )

Note This procedures assumes you are using Ubuntu’s base repositories for LibreOffice --or-- Launchpad PPA’s for LibreOffice.

May be this will help you as well.
