Uninstalling preinstalled applications

It isn't since Luca removed the Qt apps that would have used it.
Adwaita-qt is an adaptation of Adwaita(gtk theme) for use in KDE.


I use Ubuntu Cleaner to free up more space when installing Zorin updates ..... you taught me that trick more than a year ago when my Zorin downloads claimed not enough space and wouldn't continue to download ..... works great ..... :+1:

Perfect. I didn't know that.
If Luca reinstalls a qt package, will it download automatically?

Always read the small print, and keep your paws away from that attractive "Y" key when running autoremeove until you know what you will loose.
Note Bleachbit uses these clean up commands behind the scenes, so do check what it is doing.
You don't want the baby going out with the bathwater.


I do not remember if it is included in automatic dependencies (I would think it is... Gnome is so very touchy about Adwaita. :roll_eyes:)
But unless Luca uses Adwaita theme, he won't notice. If he does use it, he will notice and set about adding compatibility for Adwaita theme for the Qt app - for which there are a couple existing Tutorials & Guides threads on the topic, too.


So on State > Not installed (residual configuration)? There I see old updates leftovers despite after certain updates Software Updater asks if remove them since they're not required anymore. Seems they weren't really deleted, for example I see Signed kernel image generic and Linux kernel extra modules for version (whatever it is) on 64 bit x86 SMP that I thought they were removed once I confirmed their deletion after updating them.

I can only question how confident you are that you deleted the files or whether you did so as root.
Synaptic does not report files as removed that are in fact not removed.


All I know is that at the removal request on the Software Updater I chose to remove them since after updating them they were at 0 KB, the fact that they are still on the system is suspicious, the Software Updater request was clear, they are no longer needed.

Have you cleaned your APT Cache?

No, all I do when I read that I can remove something once updated is accepting the request to remove them, I never do anything more because I assume that's enough.

Now I could uninstall Calendar from Software Center, probably previously it was giving the unmet dependencies error so I didn't try anymore.

Evolution uninstallation left the processes evolution-alarm-notify, evolution-calendar-factory, evolution-source-registry and evolution-addressbook-factory, what about uninstalling them?

See this:


I have just searched "evolution" in Synaptic PM on my 16.3 Core that does not have Evolution app.
I cannot see those 4 items listed there at all i.e. not installed or not listed for potential installation. So I don't know where you got them from and can't advise regarding removal.

Only "evolution" items I have installed, are the essential:


These 4 processes are leftovers of the preinstalled Evolution uninstallation. On the message you shared with me they chat about evolution-data-server but I haven't it.


They should remove just fine. Try removing them from terminal and read the warnings. If it suggests that essential things will be removed, stop and say n at the prompt. Otherwise, you should have no trouble removing them.

sudo apt remove evolution-alarm-notify evolution-calendar-factory evolution-source-registry evolution-addressbook-factory
[sudo] password for luca:     
Reading package list... Done

E: Unable to find the package evolution-alarm-notify

E: Unable to find the package evolution-source-registry

My logic tells I entered the wrong command :expressionless:.

What is the output of

dpkg -l | grep -i evolution

None of the 4 processes that I have have been listed.

i suspect that


Are all contained within the packages you listed.
So - not easily removed, after-all.
