When you open the Camera app, it shows “No Camera Found. Connect a camera device” message.I still prefer the good old Cheese camera app. sudo apt install cheese
Each Ubuntu release has bugs, 24.04 is just buggier. I don’t understand how this prevalent bug made it to a long-term support release and why it has not been fixed even after the first point release of 24.04.1.If you want, you can install it using this command:
Fixing the issue
When you start the Camera app again, it should work now.
The trick here is to add yourself to the video group. You can use the usermod command for this purpose. Fortunately or unfortunately, this is a command line fix.Open a terminal in Ubuntu (use Ctrl+Alt+T shortcut) and run the following command:Here it is.I know we are not going to get answers but at least these troubleshootings help us explore an otherwise uncharted territory. 🚧This may make you doubt your machine’s hardware but it likely to be a software issue as the Camera app does not work by default in Ubuntu 24.04.
Conclusion
💡 The usermod command modifies a user account. With G you are telling it to modify the groups the user belongs. The -a option is crucial because you are asking it to append a new group to existing groups of a user. If you don’t use -a, then user will only belong to the group you specify (video here) and that will be catastrophic as you cannot use sudo and function as before.
Several workarounds have been suggested for this problem on various Ubuntu forums. However, the one that worked for me was shared by an It’s FOSS reader, Jack.Ubuntu 24.04 ships with GNOME’s new camera app and it doesn’t work. It simply fails to recognize the in-built or external webcams.sudo usermod -aG video $USER
Type the commands as it is or copy-paste them in the terminal. The -a part is of utmost important.
