I accidentally installed this app in Ubuntu. Now I want to uninstall it, but I forgot its name. How can I do it?

    Does this answer your question? How can I find all the additional packages I installed? – user535733 Feb 27 '21 at 18:54
  • The method to remove is the reverse of how you installed it, or specific to the type of app. If it was a snap, snap remove, if a deb package, apt remove etc. If an extension for gnome, it can be removed by the gnome-linked browser, or.... You've however tagged an EOL/ESM release which is now off-topic here. – guiverc Feb 27 '21 at 21:17
  • Only supported releases of Ubuntu (standard support) are on-topic for this site. Ubuntu 14.04 LTS is EOL (end-of-life) thus off-topic, and Ubuntu 14.04 ESM is in extended support and only supported by Canonical via Ubuntu Advantage thus also off-topic here. Refer https://askubuntu.com/help/on-topic https://help.ubuntu.com/community/EOLUpgrades https://fridge.ubuntu.com/2019/05/02/ubuntu-14-04-trusty-tahr-reached-end-of-life-on-april-25-2019-esm-available/ – guiverc Feb 27 '21 at 21:18
  • @guiverc, I thought 14.04 LTS is EOL in April 2022 (see https://wiki.ubuntu.com/Releases), or am I missing something? – Enterprise Feb 28 '21 at 02:01
  • Yes 14.04 ESM is EOL on April 2022 with extended support enabled, however 14.04 LTS when installed from ISO provides only standard support which has ended support already, refer https://fridge.ubuntu.com/2019/05/02/ubuntu-14-04-trusty-tahr-reached-end-of-life-on-april-25-2019-esm-available/ provided earlier. Convention here (as I understand it) is only standard support is on-topic, extended is Ubuntu Advantage provided elsewhere, though it's been, and is currently being discussed https://meta.askubuntu.com/questions/19510/is-ubuntu-14-04-off-topic-on-ask-ubuntu/19529#19529 – guiverc Feb 28 '21 at 05:47
  • @ali Raza Canonical, the maker of Ubuntu will continue to support 14.04 and 16.04 through Extended Security Maintenance until April 2024. Ask Ubuntu is currently trying to change policy to make 16.04 off topic here. ESM is free and not too hard to set up. I discus a bit about activating it at this link: https://meta.askubuntu.com/questions/19510/is-ubuntu-14-04-off-topic-on-ask-ubuntu/19529#19529 You can vote to continue Ask Ubuntu support for ESM versions of Ubuntu here: https://meta.askubuntu.com/questions/19543/policy-change-proposal-end-of-standard-support-for-esm-releases-is-effectivel – C.S.Cameron Mar 17 '21 at 11:50

You may be able to jog your memory with one or both commands below

ls -artl /var/cache/apt/archives

this will provide a list of the packages with the most recent ones listed near the end.

If an alphabetical approach appeals to you, then try

sudo apt list

When you find the package, then try

sudo apt remove pkgname

Another approach is to try finding the package name in your command history if you installed it with the terminal program

history | grep apt

will return all the commands you entered to manage packages.

If you used the dpkg command instead, then

history | grep dpkg

One thing you could do is to list all the recent installs with the command

grep " install " /var/log/dpkg.log

and see if you could find the name of the package you installed.
