Does the Snap Store Use Too Much Memory, data
On my Ubuntu 20.04, snap-store uses about 300MB memory (number 1 according to the system monitor).
- Does the Snap Store Use Too Much Memory?
- Why does the snapd service use so much data?
- If I remove snap-store, what impact will this have on already installed snaps? You will be able to continue using your existing snaps. You can use the command-line to install more snaps, remove existing ones, and, generally, do most everything. One convenience the snap store installed on your system offers is that of modifying the permissions you wish a snap to use
- Should the snap-store be using >300Mb of memory?
sudo snap remove snap-store && sudo apt install gnome-software
I find I still need to manually kill the existing process.

How Snappy packages are different from Deb
An article from PCWorld. Skype, Spotify, Minecraft, JetBrains Dev Suite, MySQL Workbench, Blender.
- Applications are no longer installed system-wide. The base Ubuntu operating system is kept securely isolated from applications you install later. Both the base system and Snappy packages are kept as read-only images.
- Snappy packages can include all the libraries and files they need, so they don’t depend on other packages.
- An update can never fail, as a package installation could potentially fail and become incomplete with typical Linux packages.
- Snappy also supports “delta” updates, which means only the changed bits of the package need to be downloaded and installed.
- Snappy-based Ubuntu systems might be standard.
Snap vs Flatpak vs AppImage
- The first big difference is that Snap is a project of Canonical that in the future intends that all Ubuntu programs will use this technology. While Flatpak is not associated with any Linux distribution and its goal is to improve the installation of the programs in Linux.
- Snap supports IoT or network services technologies while Flatpak focuses on desktop applications
- Flatpak applications can also be launched/searched from the Ubuntu desktop
Some snap commands
- snap help
- snap version
- snap list: see a list of installed snap app
- snap find queryname: find a snap app. For example snap find browser, snap find media.
- snap install appname: install snap apps
- snap remove appname: remove snap apps
- snap info appname: see more information about a snap app
- sudo snap refresh: update a snap app. You actually don't need it since snapd runs in the background and handles updates automatically
- snap changes: see a history of the changes made to your system
How to run the Snap applications: you can run snap applications just like any other application installed on your system.
# Update a package sudo snap refresh <package> # Update all packages sudo snap refresh

# List apps flatpak list --app # List run-time libraries flatpak list --runtime # Install a flatpak package flatpak install flathub de.haeckerfelix.Shortwave # Uninstall a flatpak package flatpak uninstall --delete-data de.haeckerfelix.Shortwave # Removing flatpak apps WILL NOT remove the independent runtime libraries (QT, GNOME platforms) # Run this command to get rid of them to free up disk space: flatpak uninstall --unused
Consider the Gradio app.
$ flatpak install de.haeckerfelix.gradio.flatpakref # it will ask the password in a new window $ flatpak uninstall de.haeckerfelix.gradio
Now we can launch the Gradio app from the Launch Menu.
Note: no 'sudo' is required.

How to update a flatpak app
flatpak list sudo flatpak update org.gimp.GIMP
Where are the files
AppImage & AppImageLauncher
We need to make the file executable before we can open it. Right click the file, Properties -> Permissions.
One advantage of the AppImage is portability. AppImages are usually faster than snaps or flatpaks and need less storage space. They are also easy to remove as you can delete AppImage files anytime you want without interrupting other system processes.
One problem of the AppImage files is they cannot be found in Ubuntu's launcher/search function. But check out this: Integrate AppImages To Application Menu Using AppImageLauncher.
- AppImages can be downloaded and run without installation or the need for root rights.
- The key idea of the AppImage format is one app = one file. Every AppImage contains an app and all the files the app needs to run. In other words, each AppImage has no dependencies other than what is included in the targeted base operating system(s).
- Pros and Cons No proper update system for AppImage currently. Terminal command completion solution doesn’t work
