    That duplicate was rather old and I'm not sure I'd follow any of them directly. Ubuntu desktop as installed can be see by looking here packages.ubuntu.com/bionic/ubuntu-desktop; I'd just load aptitude (at terminal) and remove anything there I didn't use, then re-install ubuntu-desktop which should drag back what you are asking for. I've seen scripts that do it (you can see what you've added usually in logs, but with snaps/flatpaks/etc & many methods there is no one place to look...) – guiverc Nov 9 '19 at 10:25

Ubuntu does not have button for factory reset. Maybe you can try install application and key Resetter to do it.

After downloading it, from ~/Downloads you must:

sudo apt install gdebi
sudo gdebi add-apt-key_1.0-0.5_all.deb
sudo gdebi resetter_3.0.0-stable_all.deb

After it you can do:

sudo resetter

If you choose automatic reset, your system will have a factory reset.

  • Very interesting but users probably may also want to clean up their home folders. – DK Bose Nov 9 '19 at 12:31

    @DKBose Resetter does that too. I explained that in an answer to the duplicate target question. – Kulfy Nov 9 '19 at 12:42
