One is traditionally distributed in deb package form and the other is distributed as a snap package
See What is the difference between snaps and Ubuntu Software Center-based apps? for details.
The differences in size
This is because of how the two distribution systems handle dependencies. Linux apps (software) depend on a lot of common files.
If it is a well known software, it's perfectly OK to install. However, software often has bugs, which either good hackers or bad hackers can discover. In the later case, unconfined app means there is a chance that software that is exploited by malicious attacker will give them access to more than just confined environment, including system and files.
I am getting this too. It might be related to removing the snap plugin, as it didn't seem to have this problem until I removed snapd and the plugin. The number of dots under the displayed image keeps increasing each time the app is started, making the window wider. I've tried purging and reinstalling the package with no success. I did find a workaround:
If you're installing program from deb-package (Ubuntu Software Center version in the question), you get program that relies on system-installed dependencies.
Pro: you only download every common part once.
Con: you can't install programs that require something that is newer than available for your system release.
If you're installing program from snap, you ...
Your repository sources are not following the correct format. They should be for example something like deb http://archive.ubuntu.com/ubuntu bionic main.
deb: These repositories contain binaries or precompiled packages. These repositories are required for most users.

I think it's likely that you had the snap installed rather than the debian package, or that you added the ppa.
The Ubuntu online package listing shows that the version in cosmic was 4.1.5, see the Krita package listing for cosmic. So it's not possible that this would have gone backwards, since all package numbers must go forwards (or stay the same) during ...
Yes, it is possible with new open-source web-application named (guess how) Linux App Store.
It is located on https://linuxappstore.io/ and allows to list all applications packed as Snap, FlatPak or AppImage and has search by name. Below is example for VLC:
and we can see it is available from all three sources.
The project is in active development, ...
There is no way to keep python3 as default on Ubuntu 16.04, because many programs including apt are written in python2.
And there is absolutely no need to set python3 as default as you can run python3 apps using python3 appname or setting python3 in shebang.
You can set back default to python2 by running:
sudo rm /usr/bin/python
sudo ln -s /usr/bin/...
Is the Multiverse repository already enabled? Check in Software and Updates (the fourth line of repositories). If not, do sudo add-apt-repository multiverse && sudo apt update or enable by clicking on it then clicking [Close].
Once Multiverse is enabled, run sudo apt install flashplugin-installer then close Firefox if it was open.
Relaunch Firefox ...
I don't think Ubuntu Software Center has that name for its package; when I entered the command apt search, I didn't got that package name in the results:
$ apt-cache search software-center
app-install-data - Ubuntu applications (data files)
software-center-aptdaemon-plugins - The aptdaemon plugins for software-center
ubuntu-kylin-software-center - Software ...
What a mess...
I've edited your original sources.list file and it should look more like this...
There may be further errors in /etc/apt/sources.list.d/*.list... for those errors you need to look at each individual error, then search *.list files and make corrections. (ie: getdeb doesn't exist any more, so you can just delete that specific .list file)...
As Dufte mentioned in his comment, your install medium is still defined as a source for packages (repository). As it is most likely not longer in the drive - accessing it fails.
To remove the install-medium from your source list, just go to settings in discover and untick the respective entry.
Maby this will help you ! :)
The procedure for manually uninstalling the AnyConnect client from a Linux or Mac OS X system is the same for both systems. As root, run the following shell script: /opt/cisco/vpn/bin/vpn_uninstall.sh
Typically, you would do this via sudo, as follows:$ sudo /opt/cisco/vpn/bin/...
Yes, there has long been a better way.
.zip, .tar, .tgz, and .bz2 files (those are what you cited) are simply compressed sets of files. They must be manually installed by the user to work. Manual installation includes manually creating the links for desktop icons.
That laborious and imprecise method of distributing software was superseded over 20 years ago ...

The celestia package was removed from Ubuntu before 16.04 due to lack of interest by the community. The previous community volunteers who had packaged the software from upstream found new interests, and no community volunteer has stepped to resume packaging in either deb or snap format.
Anybody willing to put in a small amount of effort can do the deb or ...

METHOD A: In the MATE Menu, right click "Applications > Edit Menus" then you will be able to edit the main menu.
METHOD B: Should that fail, open the Manin Menu applet, select the submenu you wish it to be in, then click the [New Item] button at upper left of the menu, and select the app you wish to add from the list of all the apps at left.
METHOD C: If ...
Debian and Ubuntu apt-get, apt, synaptic (and maybe a bunch of others) provides software packages from repositories in the "old fashioned" way of using deb files (similar to redhat rpm files which has been around for long).
These are easy to use, but installs software and libraries in the "old fashioned" way of adding them to the host operating system; which ...
Software Center includes software from three (mostly) independent sources:
The Ubuntu (.deb) repositories. Your Ubuntu system is mostly made of synchronized deb packages from here. All deb packages from the Ubuntu repositories are "official" and supported here. Deb packages from other sources are not supported here.
The Ubuntu Snap Store. This is a newer ...
Disable all the plugins in the Ubuntu Software Center if any, you can find the plugin details under the installed software.
Open the Ubuntu Software app. Go in the installed section. Fine the Gnome Software App. Click on it, scroll down until you see Add-ons. See if there are any addons enabled, disable them and it would ask to reload, do that and you ...
That's the evolution-data-server package.
Description: evolution database backend server
The data server, called "Evolution Data Server" is responsible for managing
mail, calendar, addressbook, tasks and memo information.
e-d-s is part of the Gnome and Unity desktops. It runs the integrated calendar and address book.
Since you've already figured out why there are two versions of same app. I'll answer your question briefly.
If there are two versions available, like the Claws Mail example above, which one would be the preferable, and why?
Neither of them is more or less preferred, it all depends on convinience and choices. Deb packages generally depends on some other ...
You should be able to drop to a command shell with Ctrl+Alt+F3.
From there you can log in and run some fixit commands:
sudo apt update
sudo apt upgrade --fix-missing
Then you can try to install/reinstall xubuntu-core/desktop
sudo apt install --reinstall xubuntu-core xubuntu-desktop
