The config files are one thing that many people overlooked while backing up their systems. You might want to use “ sudo nano /etc/apt/sources.list” to remove the unwanted PPAs (follow by “Ctrl + o” to save and “Ctrl + x” to exit) before you run the “ sudo apt-get update” command. Note: You will most probably have duplicate or obsolete PPA in the list after the restoration.
To backup this folder, you can use the command:Ĭat /your-backup-folder /sources.list > /etc /apt /sources.list If you are using the add-apt-repository command or the Software Sources to add your repository, they are kept at the “/etc/apt/” folder. There are two main places where your PPAs are kept. To save you the trouble from sourcing these PPA again after re-installing, you can backup your list of PPAs and restore them after the re-install. Most of the time, we will install new applications using third-party PPAs. Most of us don’t just use the default applications in Ubuntu. That will require you to use an external hard drive or partition. Alternatively, you can also use the built in backup manager – Deja Dup to backup your system. When combined, the 3 cloud storage services give you a whopping 57GB of storage space to use, which should be sufficient for most users. One good way is to back them up to the cloud, using either Dropbox, Ubuntu One or Box. Needless to say, you should always backup your important files and documents. There are several things that you will need to backup: Files and documents In case the upgrade fails and you have to re-install from scratch, you still can recover your files from the backup. No matter what, you should always backup your system. On the other hand, if you are inexperienced with PC formatting, don’t wish to spend the extra time and effort to install from scratch and don’t mind things breaking (the breaking could be minimal if you are upgrading from 11.10), upgrading using the Upgrade Manager is your best bet. This will rid your system of any old and useless files, applications and settings. My advise is: if you are using a much older version of Ubuntu (11.04 and below), it is good to reformat your PC and install from scratch. However, I have read news that the upgrading process in Ubuntu Precise is much smoother and less things are breaking, so it might worth a try. This is worst if you are two or more versions behind as the transition from GTK 2.x (11.04 and below) to GTK 3.x (12.04) would undoubtedly break some of your applications and settings.
Downloads are slow, upgrade took forever and the completed product always break things here and there. In my past experience, upgrading an existing version of Ubuntu to the latest version always left a bad taste in the mouth. Decide whether to install from scratch or upgrade your existing version
