How to Install Wine 4.9 in Ubuntu:
1. Open terminal either via Ctrl+Alt+T keyboard shortcut or by searching for ‘terminal’ from app menu. When it opens, run following commands to download and install the key:
Many popular applications (e.g., PyCharm, Blender and even Firefox) provide Linux tarball that include executable files can be run directly to launch the apps.
However, we need to manually create app launcher, to make it possible to launch them by searching the apps from start menu (‘Activities‘ overview). And, ‘Arronax’ is the app to do the job easily.
The .desktop files
App launchers in Linux are handled by files via .desktop extension. Each app you can see in system start menu has an associated .desktop file in either ‘/usr/share/applications‘ or ‘.local/share/applications‘ directory.
For portable Linux tarball, or appimage that does not have an app launcher, user may manually create a .desktop file in either directory to link app into system start menu.
Arronax:
KDE, Cinnamon, and XFCE now have built-in utility to create desktop app launcher. But, GNOME does not!
Arronax is the simple tool started almost 10 years ago, with ability to create and edit .desktop file.
With it, user may either right-click on the executable file and select ‘Create a Starter’, or open the app by searching from start menu (‘Activities’ overview):
For basic function, just type name to display in start menu, select executable file for ‘Command’ box, and choose an icon! Save it to the right location, and that’s all!!
All other options are optional! Though, you may move cursor over an option to get tool-tip tells what it does, and enable it as need.
Finally, click on “Save” button. In the bottom of file save dialog, user may choose the standard location to save the .desktop file.
“User app folder” – stores app launcher files for current user only.
“System app folder” – stores app launcher files for all system user.
“User / System Autostart folder” – store app launchers start automatically on start up.
NOTE: save to system folder needs to run Arronax as root (run sudo arronax in terminal).
How to Install Arronax in Ubuntu:

Ubuntu 18.04 is quite slow to boot up in my laptop in the last few days. It was stuck at the purple screen with Ubuntu logo in center for more than 1 minute before booting into the login screen.
When it was booting into the purple screen, press F2 to show the white and black text screen. There it told me that it was stuck at:
“A start job is running for dev-disk-by\x2uuid …(35s \ 1min 30s)”
To fix the problem, do following steps one by one:
UPDATE: First make a back up of /etc/fstab before editing the file by running command:
sudo cp /etc/fstab /etc/fstab-backup
1. Open terminal from application menu or by pressing Ctrl+Alt+T on keyboard. When it opens, run command:
sudo -H gedit /etc/fstab
Type user password (no asterisk feedback) when it prompts. It will open fstab (file system table) configuration file with gedit text editor.
2. When the file opens, you’ll see something look like this:
As the top picture shows, “UUID=1cdb9a5b-01a7-4b7b-a0ad-ce73676bb7c1”, mounting the Swap partition takes 1 minute and 30 seconds to boot up Ubuntu.
3. Launch Disks utility from application menu.
4. When it opens, check the Swap partition, and it obviously that the UUID value does not match the one in /etc/fstab.
5. So what I need to do here is to replace the UUID value with the correct one copied from Disks utility.
