Attempt to remove annoying hanging debian system due to libreoffice's unstablity

Remove configuration of libreoffice.
$ cd ~/.config
$ rm -rf libreoffice

Remove libreoffice
# apt remove --purge libreoffice*
# apt clean
# apt autoremvoe

Remove default-jdk, default-jdk-headless, default-jre, and default-jre-headless
# apt remove --purge default-jdk default-jdk-headless default-jre default-jre-headless
# apt clean
# apt autoremove

Reinstall default-jdk, default-jdk-headless, default-jre, and default-jre-headless.
# apt install default-jdk default-jdk-headless default-jre default-jre-headless

Reinstall libreoffice
# apt install libreoffice

Finally, wait, and see....

when libreoffice is unstable slow, I would use libreoffice-qt5 instead of libreoffice-gtk3.
