Over-zealous Janitor - Deleted software I am using

Asked by Todd Edelman

 I am using Maverick 10.10. I ran Computer Janitor and for some reason it identified Opera and Google Earth as being unused or something, and I suppose I did not understand exactly how to use this - i.e. thought it was simply throwing away installers etc. - so it removed both. Some other things on list I did not really recognize were removed as well but not sure if this has done anything -- I have not noticed. Neither Chrome nor Firefox were removed. I did not have anything saved in Google Earth and dont care but Opera is different. I looked and it is still in my main directory or whatever but apparently/obviously uninstalled (i.e. all the bookmarks etc are there in the files). There is also still some kind of artifact of Opera on the top menu bar on the Desktop.

I then opened Synaptic Package Mgr. and checked Opera for installation and got the message "Could not mark all packages for installation or upgrade. opera: Package opera has no available version, but exists in the database. This typically means that the package was mentioned in a dependency and never uploaded, has been obsoleted or is not available with the contents of sources.list" and with no option to do anything but close the window.

Not sure how to proceed.... if I install with Ubuntu Software Centre will all the bookmarks, settings, history be saved and used as part of the new installation? Or do I do something different?

On the top panel instead of the Opera launcher graphic there is a big grey rectangle. It identifies as the Opera launcher - if I right-click and open a window - but will not launch.

it DOES warn you to check over the list to see what you want to keep before deleting everything. you can just reinstall the deleted programs.

if you want something safer, you should install bleachbit and use that instead of janitor.

Thanks, Marcus! So if I reinstall Opera it will utilize the bookmarks, etc. already in the main directory and used by the just "cleaned" installation of Opera?

Thanks for info on bleachbit. It was also suggested to me to just use Terminal and sudo apt-get clean.

Sure, the opera settings and such are stored in $HOME. Simply reinstall the app and you should be fine. You can always restore the bookmarks etc from your backups if worst comes to worse.

If space is an issue you can also remove old kernels to save ~120Mb per kernel.

Thanks again. I thought I had provided additional info which is that Opera does not appear in Software Centre. As I understand I am not supposed to install via a download straight from the Opera website.

If you run:

gksudo gedit /etc/apt/sources.list

add this line:

deb http://deb.opera.com/opera/ stable non-free

Save the new file and close gedit, then run:

wget -qO - http://deb.opera.com/archive.key | sudo apt-key add -; sudo apt-get update

If you get no warnings about unauthenticated packages then run:

sudo apt-get -y install opera

Oh, my apologies, downloading from the website activated Software Centre and everything is fine. Thanks again for your assistance , Marcus and Parsnip.
