The latest Linux Mint 20.1 introduced a new application, Web App Manager, allows to turn any web pages into desktop applications. Like a normal application, web app has its own window, its own icon, and can be launched from system app menu.

Ubuntu used to have web apps integration when it was Ubuntu 14.04. The project was however discontinued.

For those want to try out the new Web App Manager from Linux Mint, here’s how to install it in Ubuntu 20.04.

Download & Install the DEB binary via direct link:

If you just want to try it out, the DEB binary package is available to download via Linux Mint ftp download page:

Download Web App Manager (.deb)

Grab it and install the package either via Gdebi package installer or by running command in terminal:

sudo apt install ./Downloads/webapp-manager*.deb

Add Linux Mint repository & Receive software udpates (for Web App Manager only):

You are able to add Linux Mint repository and only receive updates for the app from that repository.

1.) First download the key (it’s “linuxmint-keyring_2016.05.26_all.deb” so far):

Linux Mint Keyring

And install it via command:

sudo apt install ./Downloads/linuxmint-keyring*.deb

2.) Add Linux Mint 20 repository by running command:

sudo sh -c 'echo "deb http://packages.linuxmint.com ulyssa main" >> /etc/apt/sources.list.d/mint.list'

3.) Set the priority to make Ubuntu only install webapp-manager from Linux Mint repository.

Run command to create and open the configuration file in text editor:

sudo gedit /etc/apt/preferences.d/mint-ulyssa-pin

When it opens, paste below lines and save the file.

# Allow upgrading only webapp-manager from Ulyssa repository
Package: webapp-manager
Pin: origin packages.linuxmint.com
Pin-Priority: 500

# Never prefer other packages from the Ulyssa repository
Package: *
Pin: origin packages.linuxmint.com
Pin-Priority: 1

4.) Now run apt update command to refresh your system package cache:

sudo apt update

5.) Before installing the webapp-manager package, try command:

sudo apt install webapp-manager --simulate

It won’t really install the package, but only list which packages will be installed, including the package versions (which marked with package source, Ubuntu or Linux Mint).

6.) To finally install the application, run command:

sudo apt install webapp-manager

How to Remove Web App Manager:

To remove the application, simply open terminal and run command:

sudo apt remove --auto-remove webapp-manager

To remove the Linux Mint repository, remove the relevant line from Software & Updates -> Other Software.

And you may also remove the config file created to set the priority, via command:

sudo rm /etc/apt/preferences.d/mint-ulyssa-pin

Webby is an open-source project similar to Fogger, it allows to use Facebook, Youtube, or any web app as a normal desktop app in Ubuntu.

Chrome, Firefox, Opera, IE… all these are web browsers with a big toolbar and tabs. In the new era of web apps, it doesn’t makes any sense. Webby allow to use Facebook, Youtube or any web app as a regular desktop apps, integrated with the OS, without tabs and using the default system launcher.

With Webby browser, you can turn any web page into a regular desktop app via 4 steps:

• paste or type in the url
• give a name
• set a launcher icon.
• finally click the Create app button.

Once Webby successfully created the app, you are able to launch it from the Unity Dash or App Menu immediately.

Below are the GMail and Facebook web apps created by Webby:

How to Install Webby in Ubuntu:

The developer has created an official PPA for this web app browser, currently available for Ubuntu 14.10 and Ubuntu 14.04.

Open terminal from the Dash or by pressing Ctrl+Alt+T on keyboard. When it opens, run commands below one by one:

sudo add-apt-repository ppa:erasmo-marin/webby-browser

sudo apt-get update

sudo apt-get install webby-browser

NOTE for Ubuntu 14.04 LTS user: Since the app depends on GTK >=3.12, 14.04 Trusty needs Gnome 3 PPA and Gnome 3 Staging PPA (might broken your desktop) for the dependencies.

If you still want to try this browser in Ubuntu 14.04, run below commands to add the PPAs before running previous 3 commands:

sudo add-apt-repository ppa:gnome3-team/gnome3

sudo add-apt-repository ppa:gnome3-team/gnome3-staging

Once Webby is properly installed, remove Gnome 3 staging PPA to avoid issues:

sudo add-apt-repository -r ppa:gnome3-team/gnome3-staging
