You’ll find the “X issues to do instantly after putting in Linux” articles in all places. I even penned one myself.
What you do not at all times see are articles telling you what not to do after putting in the open-source working system and I am right here to finish that drought. Why?

Is not Linux in regards to the attainable and never the not possible? It most definitely is. However that does not imply new customers should not be warned about sure issues. With such warnings, new customers are higher ready to have a optimistic expertise with Linux and that is why I do what I do.
Here is what to not do after you put in Linux.
1. Do not add random repositories
Repositories are distant areas that home software program put in by way of the built-in bundle supervisor. For example, you’ll be able to set up GIMP from the default Ubuntu repositories with the command sudo apt-get set up gimp -y. Default repositories are these which can be routinely configured by default.

With most Linux distributions, you’ll be able to add all of the third-party repositories you need. The massive query is… must you? In all probability not. Why? Simply because a repository is accessible doesn’t suggest you want it or that it is secure. There have been repositories found to include malicious software program. Due to that, I solely add repositories from trusted sources (similar to a recognized vendor). When you run throughout a repository for an app you may want however you do not know the developer or the corporate, do a little bit of analysis earlier than utilizing it.
2. Do not log in as root
As soon as upon a time, logging in as root was crucial. What we did not know was that doing so may result in safety points. Now, some distributions have the basis (admin) account locked down. Ubuntu, for instance, does not even ship with a root consumer password, so logging in as root can’t be achieved except you allow the consumer.

In case your distribution of selection permits logging in as root, do not. In case your distribution permits you to su to the basis consumer, do not. As a substitute, use sudo to realize admin privileges for a command. When the basis consumer is enabled, ought to somebody acquire entry to that consumer, there’s nothing they can’t do in your system. As a substitute of working that danger, by no means log in as root. Ever. Interval.
3. Do not delete random information
There are specific directories in Linux that include crucial system or configuration information that might wreak havoc in your machine in the event that they have been deleted. Recordsdata in /usr/bin, /usr/sbin, /bin, /dev, /lib/, /sbin, and /var needs to be thought-about untouchable. Recordsdata in /and many others (that are configuration information) ought to solely be edited if you realize what you are doing.
Deleting any file from these directories may trigger issues you may not have the ability to resolve. So, even when your system is low on drive house, don’t contact information in these directories. In case your machine’s inner storage is getting cramped, look in your ~/Downloads listing or different locations in HOME to take away information. Even then, solely take away for those who’ve made a backup of your knowledge.
Talking of which…
4. Do not ignore backups
Regardless that Linux is extremely secure and safe, your knowledge may not be. You may by chance delete that guide you’ve got been engaged on for months or a report you should hand in tomorrow. To err is human, so it is crucial that you simply recurrently again up these vital information.

I at all times arrange an automatic, each day backup for the ~/Paperwork listing. You must do the identical for any listing that homes vital information. Thankfully, there are many user-friendly GUI backup options (similar to Deja Dup) that make this course of quite simple.
5. Do not set up desktop environments that may break the default
I used to randomly set up any/all desktop environments that regarded attention-grabbing. Again within the day, it was pretty simple to do this with out worrying I would break the default DE. Nowadays, that is not at all times the case. Certain, you’ll be able to set up most desktops in your favourite distribution and be okay. Proper now, I’ve each the default Pop!_OS desktop and Budgie Desktop. The issue is there are specific desktop environments that may battle with each other.
Additionally: The new COSMIC Linux desktop from System76 is out of this world
For instance, I am unable to set up Pantheon (as a lot as I would prefer to) on Pop!_OS with out it inflicting issues with the default. If I set up Plasma Desktop, I am going to almost certainly wind up with duplicate entries for apps in my desktop menu. Due to this, I at all times suggest customers choose a distribution that defaults to the desktop surroundings they need. If a brand new desktop is desired, I recommend first doing a little bit of analysis to see if the brand new desktop will battle with the default. If there are conflicts, I will not run the set up.
6. Do not set up server software program on a desktop
If I wished to, I may set up an online server, a database server, a container surroundings, a CMS, or absolutely anything on my Linux desktop. I do not do this. Why? There are a number of causes.

First off, for those who want server software program, you are higher off utilizing a server OS (similar to Ubuntu Server, Debian Server, AlmaLinux, Fedora Server, and many others.) as a result of these distributions are created particularly for server use. They’ve safety mechanisms and different software program geared for such duties.
Second, you do not need your desktop to be slowed down with server processes that might take up essential CPU cycles. Third, you do not need your server software program to be compromised as a result of common customers are logging in.
When you want server software program (both to your residence or enterprise), set up a server OS on a devoted machine (or digital machine) and go from there. The identical factor holds true for a server-centric Linux distribution in that you simply should not use it as a desktop OS.
7. Do not disable SELinux or AppArmor
Talking of safety, by no means disable SELinux or AppArmor. Why? These are crucial safety layers that serve a really particular function that might be onerous to duplicate with one other piece of software program. I’ve heard from so many admins who disable SELinux as a result of they both do not perceive the way it works or haven’t got the time to discover ways to use it.

While you disable SELinux or AppArmor, your programs grow to be susceptible to assault. Simply do not do that. Ever. Go away the safety measures alone so Linux does not grow to be a legal responsibility. Out of the field, Linux is sort of safe, due to providers like SELinux and AppArmor.
And there you have got it, the issues I by no means do with a brand new Linux set up. Really, I by no means do these with any Linux set up, regardless of how lengthy it has been up and working.
