While I love using Ubuntu, I’ve made my share of (sometimes disastrous) mistakes while using it and wanted to share them so no one else falls down the same dark paths that I have walked.
5. Not using the Long Term Support (LTS) Versions
Each version of Ubuntu just keeps getting better and better, but sometimes upgrading to the latest version isn’t the best choice. If you don’t have a lot of patience (or a slow internet connection) this could be problematic as an upgrade could take several contiguous hours, which not everyone can spare. Then of course there are the problems upgrading from one version to another, such as certain programs not working correctly or packages being corrupted, etc. Avoid it all by just sticking to the LTS versions. You’re not missing anything important by playing it safe; rather, you’re saving yourself hours of headache because you’ll only need to update every 5 years instead of every 6 months.
4. Using the command line for something that could have been done through the GUI easily
Learning how to use the command line is important, but if you know your stuff already it’s better to just take the GUI route when you can. Why? The GUI is usually robust enough to avoid making the mistakes you’d make if you were allowed free access to the guts of your Linux distro. The Software Center already knows everything that is has to do, so there is no guess work and no need to cross your fingers. A single mis-typed character on the command line could send your entire computer into utter chaos and you’d never know why.
