How To Fix do-release-upgrade: command not found Error In Ubuntu

How do I enable accessibility alt-key shortcuts in GNOME window menus

Bounce keys is almost a similar feature. Intended for users with physical disabilities, bounce keys is a feature that tells the system to ignore repeated and rapid presses of the same key based on its configuration. You need to turn these features off to restore the input to the default state.

In my case the TTY device name was ttyUSB0; however, if your cable is not a USB converter, then it might be named ttyS0 instead. If your system architecture is ARM, you might see a name like this ttyAMA0 and if it is a Samsung, then the device might be named ttySAC0. There are more serial port names than I mention here. Also, the index number at the end of the name is determined by the devices minor number and may not be 0. The device name for a serial connection is properly referred to as a serial port. The rest of this blog post will simply use ttyUSB0 as the name of the serial port, but you must use the correctly named serial port assigned to your connected device if you are following along.

Sed is a stream editor for filtering or transforming text. In this case, we will use sed to remove the line that contains the string password.

GNOME Desktop Icons — As it turns out, if you are not able to use your keyboard only on the desktop, such as deleting a file or whatever, it could be due to the bugged desktop icons that have been reported by users. A fix to this would be to update your system to the latest upgrades available.

What is hiding Ctrl + Shift + Alt + Up/Down

The output from ls shows us that the uucp group has rw permissions to the device. Another common group that is used for the group ownership of serial devices is the dialout group. If your system uses the dialout group rather than uucp, then in your mind simply substitute dialout in place of uucp for the rest of this post. It makes semantic sense for the dialout group to be used if the device is a modem or a fax.


This is the most obvious thing that you should do whenever you face any issue regarding your keyboard. As it turns out, if you are not able to use your keyboard, it could be due to the keyboard layout being of a different language. If this case is applicable to you, the resolution is pretty simple.

The names of each setting in your custom configuration file should match mine with the exception of the port name. If you edited any other lines, even if you did not change the value, the edited setting will also be written to the configuration file. For example, if you edited the line speed, then you will also see settings for baudrate, bits, parity and stopbits.

For Gnome Shell, the workspaces stand in the way. Even the keyboard shortcuts differ a bit to Phpstorm (in my case there was the shift modifier which was not part of the Gnome shell shortcut binding), the workspace up/down block the keybindings in Phpstorm.


Edit: I created a new user, the alt issue is not present in that account. After switching back to my original account, the alt issue was not present either until the next reboot.

If you are not able to use the keyboard only on the desktop screen and it works (more hints) perfectly fine everywhere else, then it is probably because of the bug with the gnome desktop icons. If this case is applicable to you, it is evident that your system is not up-to-date and needs to be updated as this bug has been fixed.

I recently wrote about my first experience connecting to the pinephone via serial console. This post documents how to configure Minicom for establishing an interactive terminal session with a device connected to your computer via a serial port. The configuration will be saved to file so that it can be reused to connect to the same device again in the future, which is convenient. My version of minicom at the time of writing is minicom version 2/7 (compiled Jan 8 2021).


Keyboard Layout — One of the main reasons your keyboard may not work is if you have the wrong keyboard layout selected in the settings. If you installed a fresh copy, it could be that you selected the wrong layout or the upgrade might have messed the keyboard layout settings. This can be easily resolved by choosing the correct keyboard layout.

Slow keys and bounce keys are features of the GNOME desktop environment. Slow keys is basically a feature that puts a delay between when the letter key is pressed on the keyboard and when that letter is displayed on the screen. If the slow keys feature is enabled, you will have to hold each key that you wish to press before it is registered.


Slow Keys Enabled — Another cause of the problem can be the slow keys feature that comes in the GNOME desktop environment. If this case is applicable to you, you just have to disable the slow keys feature from the accessibility menu and you should be good to go.

Ubuntu is the most popular as well as the most widely used Linux distribution. The new LTS release of the distro brings many new features and much faster boot time. If you are an LTS user, upgrading to the new release is an obvious option. However, for some users, that didn’t go so well. Users have reported that their keyboard and mouse stopped working (learn more) after they installed the newest release. The main problem has been with the keyboard though.

You will see a lot of output being written to the screen as your device loads. In the end, you should see a login prompt. Since minicom is a terminal emulator, you can click on the screen and enter your login credentials as if you were connected to the device with a keyboard and monitor.
