10 Common Linux Problems and How to Solve Them

If you’re immersed in the Linux world or just considering taking the plunge, you’ve probably wondered: what issues might I encounter and how do I solve them? Well, don’t fret, because here I bring you some of the most common hiccups you might come across and, of course, how to navigate them.

System won’t boot after an update

Imagine: you just did an update and suddenly, bam! Your system won’t boot. It’s a pain, but there’s a solution. Chances are, something with the kernel or the drivers isn’t playing nicely.

Solution: One option is to boot using an older kernel. When the GRUB menu (boot manager) appears, select an older version of the kernel. If everything runs smoothly, you might want to stick with that kernel until issues with the new one are resolved.

Wi-Fi connection doesn’t work

Sometimes, Linux can be a bit finicky with Wi-Fi drivers. If your connection isn’t working, you might need to install or update the appropriate driver.

Solution: Connect your computer to the Internet using an Ethernet cable and look for the right drivers for your Wi-Fi card. Typically, your distribution’s driver manager will provide options for installation.

Screen resolution issues

If your display looks blurry or the resolution is off, Linux might not be correctly recognizing your monitor or graphics card.

Solution: Head to your system’s display settings and try different resolutions. If that doesn’t work, consider installing or updating the drivers for your graphics card.

No sound

Can’t hear anything? What a drag! But don’t get stressed, it’s often an easy fix.

Solution: First, ensure the sound isn’t muted and the volume is at an appropriate level. If that doesn’t do the trick, go to the sound manager and make sure the output is configured correctly. Lastly, if it’s still not working, you might need to install or update your sound drivers.

Can’t install a program

Linux has a plethora of software repositories, but sometimes, the program you want isn’t there.

Solution: Look for a .deb or .rpm package on the program’s official website. Once downloaded, open your distribution’s software center and follow the installation instructions. If the software doesn’t offer Linux packages, you could try tools like Wine to run Windows applications.

System freezes

It’s rare, but it happens. If Linux freezes up on you, there are a couple of things you can try.

Solution: Attempt to switch to a virtual terminal by pressing Ctrl+Alt and an F key (from F1 to F7). From there, you can try restarting the graphical interface with sudo service lightdm restart or the appropriate command for your display manager. If that doesn’t work, you might need to reboot your machine.

File permission issues

If you get a message saying you don’t have permission to access or modify a file, don’t despair.

Solution: Open a terminal and use the chmod command to change the file’s permissions. If you’re unsure how to use it, look up a guide on chmod and chown. But be careful and make sure you know what you’re doing.

System doesn’t recognize my USB

Sometimes, when you plug in a USB device, Linux doesn’t recognize it.

Solution: First, try plugging it into a different port. If that doesn’t work, open a terminal and type lsusb to see if the system recognizes it. If it’s on the list, you might just need to manually mount it.

Errors when updating the system

On occasion, when trying to update, you can run into errors that prevent completion.

Solution: Open a terminal and run sudo apt-get update followed by sudo apt-get upgrade (or the corresponding commands for your package manager). If you encounter errors, try searching for them online; someone has likely already found a solution.

Can’t access an SSH server

If you’re having trouble accessing a server via SSH, you’re not alone.

Solution: Make sure the SSH service is active on the server and that there’s no firewall blocking port 22. You might also need to generate or renew your SSH keys on your client machine.

And there you have it! Some of the most common issues you might encounter while using Linux and how to address them. Remember, the Linux community is vast and always willing to help, so if you hit a snag, someone else has likely been through it and can lend a hand. Keep up the spirit and enjoy Linux!
