How can I uninstall Opera from Xubuntu?

I have downloaded opera from the website (deb package) and installed it. Now I want to remove it but I don't know how. I tried sudo apt-get remove opera but it didn't work.

Solution 1:

@Thomas W.'s answer didn't work for me on Ubuntu 14.04. I had to use:

sudo dpkg -r opera-stable

And to remove the apt sources file added by Opera:

sudo rm -f /etc/apt/sources.list.d/opera-stable.list

Solution 2:

When you install via the downloaded .deb binaries/installer and not the opera repository for Opera, then it was installed with dpkg, and not apt-get.

Try using sudo dpkg --remove opera or sudo dpkg -r opera to remove it.

Solution 3:

sudo apt-get remove --purge opera-stable

Try this, it's gonna work.

Solution 4:

Use

dpkg -l | grep opera

to find out proper package name. For me opera-stable then

sudo apt-get remove opera-stable
