The following article provides information on how to upgrade or repair the Ubuntu Operating system on a Dell PC.
Ubuntu as with any other operating system is constantly looking to improve and better it's usage and performance. What is different with Ubuntu is that you have the option of two updates at any time :
This update is available every two years and is fully supported by Canonical with updates for five years. It's considered a tested and stable build.
This update is available every 6 months and is only supported by Canonical with updates for 9 Months. These normal releases are considered to be cutting edge but can have issues because of this. These builds are usually used by testers and developers.
Each upgrade looks to add new features and make old features work better. It also looks to make itself more compatible with new hardware and software. To get the best use out of your system, it's best to have your system up to date.
This guide deals with three types of install. I'll quickly go over the differences and then we have the various how to's in the sections below :
This type of install is where you move to a more recent revision of the operating system, whilst keeping all of your programs, settings and data intact. Everything is saved and used during the install so you don't need to redo or reinstall anything.
This type of install is where you create a new partition or install over only one of the old partitions so that you're programs and data and protected. This is usually done by copying the new libraries over the old ones in the / partition. It's much the same as the old XP Repair install where it copied the windows directory over the top of itself to try and resolve system issues without a clean install.
This type of install is a last resort. It's where you format the Hard Disk Drive (HDD) and start again from scratch. This is usually done only after everything else has failed or you are configuring a new system.
These commands will mostly be run in Terminal. (CTRL+ALT+T will open Terminal in most Ubuntu builds.)
Make sure your current version is fully up to date.
Install the Update Manager Core Package.
Run the following commands to check the current version and the kernel information.
Use this command to update/upgrade to the next available version.
You will see a series of onscreen prompts that take you through the upgrade. I can't tell you how to answer the prompts, as it depends on what type of installation you want to end up with.
If you are looking to perform a repair install or to customise your upgrade install further, you can approach the issue in a different manner.
First you will need to go to the Canonical site and download and burn an ISO of the operating system version you are upgrading to.
There are Dell Ubuntu images available from Dell sources. However if you aren't sure which particular custom image suits your particular system, then I would advise you stick with a base build and work from there.
To upgrade using the media you just burned, you need to run the installer.
Choose the Something Else option, select your Ubuntu partition and click Edit Partition.
Set the mount point to /. If you have any other partitions, for instance /home or /boot, then set those up too.
Click Next and it asks a question that essentially means Linux is already installed on /, this will erase your existing system files only, answer Yes.
Your /home folder will be saved, even if it is in the same partition as /. Your package list is saved and newer versions for 16.04 will be installed into the new system for you.
Most of this is covered in the article linked below :
If you have attempted an upgrade install and a custom/repair install and you're still experiencing issues, you may need to look at performing a clean install instead. This is usually done as a last resort as there will be data loss.
In order to perform a clean install please follow the link below to a step by step guide.
