Installing Bottles for Wine in Ubuntu 22.04

Refer; https://linuxcapable.com/how-to-install-bottles-on-ubuntu-linux/

Install Flatpak for Bottles Installation (Skip if Installed)

Begin by installing Flatpak, which the package manager requires for bottles. If Flatpak is already in your system, you can skip this step.

sudo apt install flatpak -y
reboot

Enable Flathub for Bottles Installation

To proceed with the installation of Bottles, enable Flathub repository with the following command:

sudo flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Finally, install Bottles using Flatpak. Run the command below in your terminal:

flatpak install flathub com.usebottles.bottles -y

Launch Bottles from the command line or through the GUI

flatpak run com.usebottles.bottles

This command instantly activates Bottles, providing immediate access to its features. Using the command line for launching applications like Bottles is a direct approach many users favor for its speed and simplicity.

For those who prefer a graphical user interface (GUI), Bottles can be launched without using the command line. Follow these steps to open Bottles through the GUI:

  • Click on Activities at the top left corner of your screen.
  • Select Show Applications to view a list of all installed applications.
  • Scroll to find and click on the Bottles application icon.

Work through the settings, it seems like have an installer is a good thing.

Quick solution:

With this kind of error, I usually start by raising the postBuffer size by:

git config --global http.postBuffer 524288000

(some comments below report having to double the value):

git config --global http.postBuffer 1048576000

Skip password with sudo command

To execute the systemctl restart bluetooth command without entering a password on Ubuntu Linux 20.04, you can set up a specific sudoers configuration. This allows your user account to execute this specific command without being prompted for a password.

Follow these steps:

Open the sudoers file using the visudo command. It's essential to use visudo to edit the sudoers file to prevent syntax errors:

sudo visudo

Scroll down or navigate to the bottom of the file and add the following line:

your_username ALL=(ALL) NOPASSWD: /bin/systemctl restart bluetooth

Replace your_username with your actual username on the system. This line grants your user account permission to run the specified command without a password prompt.

Save the changes and close the editor. In visudo, you can save by pressing Ctrl + X, then Y to confirm changes, and Enter to exit.

Now, when you run sudo systemctl restart bluetooth with the specified username, it shouldn't prompt for a password. Remember to be cautious when modifying sudoers, as incorrect settings might impact system security. Always follow best practices and ensure you're aware of the security implications.
