How do I install Albert on Ubuntu 18.04?  I tried to install it from the terminal following a tutorial for Ubuntu 17.10 but that didn't work for 18.04.  So I purged Albert and want to try again but there is no tutorial targeted for Ubuntu 18.04 LTS.

I know the thread  However, there is no Linux anymore in the installation site .  Unsuccessful attempts   I do DriraWassim's proposal which does not add anything to apt-get and does not show the installed .deb package in the path/search  sudo apt-get install libxml2:i386  sudo apt-get update sudo apt-get upgrade  apt-cache search adobereader-enu   I download the newest .deb package  and run it.  I cannot find the application anywhere in the system. It is not in the path and not in Ubuntu's search. How can you start it?

^^^^ Will Ubuntu GNOME upgrade to Ubuntu 18.04, or will support discontinue when 18.04 is released?? Just want to know what's better to run right now so I can upgrade and not have to reinstall later(I intend to see this transition through)-- GNOME installed correctly on vanilla Ubuntu, or Ubuntu GNOME?

After doing a man apt-get and cursory Google search it's not clear how I find new programs to install (from the internet) using apt-get (which is amazingly powerful and simple coming from another Linux distro).  I'm using Ubuntu Server 8.04 LTS (an inherited system used for some random work), so no GUI.  Anyone have quick advice here?

I hope you can help me. I installed Ubuntu 18.04 a few days ago and, while trying to configure it and installing new packaged and software, I think I did something bad. I think it could be related with installing python. Anyway, netiher the gnome-terminal or gnome-tweaks can´t start anymores. Also, when I try to update (sudo apt-get update) it gives me the following error:  sh 1: /usr/lib/cnf-update-db: not found Reading package lists... Done E: Problem executing scripts APT::Update::Post-Invoke-Succes 'if /usr/bin/test -w /var/lib/command-not-found -a -e /usr/lib/cnf-update-db &gt; /dev/null; fi' E: Sub-process returned an error code   I am relativeley new to Linux so I have no clue how can I fix this. Any idea? Even to restore defult configurations/settings?  Thank you very much!

This option seems to have gone away after upgrading from Ubuntu 16.04. I tried installing nautilus-open-terminal but it is unable to locate the package for 18.04. Also trying to install nautilus-actions gives:  Package nautilus-actions is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source     How to fix this?

I would like to ask a very basic question but I have never thought about it before. Well, when someone installs an application from terminal, he has to add the repository first, right? On the other side, when someone installs an application from the Ubuntu Software Center, is the repository then added automatically?  I am asking those questions to figure out this: When I run update and then upgrade, will this application be upgraded or not? Is the result same in two options?

I just installed Ubuntu 12.10 (amd64), and want to install a recent version of MySQL 5.6.  If possible, I would like to install (not upgrade) it the "Debian Way' (i.e., using apt-get or dpkg).
