This tutorial shows how to add (or remove) the “proposed” repository to install (or downgrade) the pre-released packages\/updates in Ubuntu.<\/p>\n

As you may know, Ubuntu has an area called proposed<\/code> for updates that are being tested before publication. It’s recommended for developers and users who are interested in helping to test updates and provide feedback.<\/p>\n

The proposed<\/code> repository is disabled by default. If you want, here’s how to enable it in all current Ubuntu releases.<\/p>\n

<\/p>\n

Why to Enable Proposed Repository<\/h3>\n

As mentioned, the repository is for testing and developing purpose. Software developers and\/or users who can’t wait for new updates may want it.<\/p>\n

In my case, I was going to try out the new GNOME 48 Beta in Ubuntu 25.04 daily build. Most desktop packages were ready to install\/update, but few core libraries, e.g., Gnome Control Center, were still in being tested. Without waiting for few more days, I needed to enable that repository for testing all the new features in Gnome 48.<\/p>\n

NOTE: The Proposed repository is NOT recommended for production machine, as it might break things!<\/b><\/p>\n

1. Enable the “Proposed” Repository<\/h3>\n

User can enable the repository by either a graphical toggle option or editing the configuration file from command line.<\/p>\n

Option 1: Use Software & Updates (Graphical Option)<\/h4>\n

First, launch Software & Updates<\/b> utility. When it opens, navigate to Developer Options<\/b> tab and enable the “Pre-release updates” (codename-proposed) option. Finally, click Close<\/b> then Reload<\/b>.<\/p>\n

\"\"<\/a><\/p>\n

Some Ubuntu flavors may NOT have the Software & Updates<\/i> utility. In the case, user may try running command sudo software-properties-gtk<\/code> (for GTK based desktop) or sudo software-properties-qt<\/code> (for Qt-based desktop) to launch from terminal.<\/p>\n

Option 2: Edit Configuration File<\/h4>\n

For Server without desktop environment, or users who want to do the job from command line, open terminal (Ctrl+Alt+T) or connect to remove server, then do:<\/p>\n
