• Pop!_Planet is still very much under development. Data for the wiki is being sourced from the Arch Linux and Ubuntu wikis, along with a bunch of completely unique content specific to Pop!_OS, and sourcing, converting and updating that content takes time; please be patient. If you can't find what you're looking for here, check the Arch Linux and Ubuntu wikis.

Frequently asked questions

General

What is Pop!_OS?

See the Pop!_OS article.

What architectures does Pop!_OS support?

Pop!_OS only supports the x86_64 (sometimes called amd64) architecture.

Does Pop!_OS support ARM CPUs?

Not at this time.

I am a complete Linux beginner. Should I use Pop!_OS?

Sure! Pop!_OS is designed for creatives, but since it is based on Ubuntu, it is easy enough for anyone to install and configure a fully functioning system.

See also the Installation guide.

I really like Pop!_OS, except the development team needs to implement feature X

Get involved, contribute your code/solution to the community. If it is well regarded by the community and development team, perhaps it will be merged. The Pop!_OS community thrives on contribution and sharing of code and tools.

When will the new release be made available?

When it's ready.

Is Pop!_OS a stable distribution? Will I get frequent breakage?

Yes and maybe. Pop!_OS itself is very stable, in no small part due to the testing that goes into the Ubuntu releases that Pop!_OS is based on, as well as the further testing and tweaking done by the System76 team. However, any operating system is only as stable as you let it be. If you like tinkering and tweaking on your own, things may break. If you install unstable or prototype software, things may break.

Pop!_OS needs more press (i.e. advertisement)

Bring it up with the Pop!_OS team. This is an unofficial community-backed resource, we have no direct control over Pop!_OS or its advertising efforts.

Pop!_OS needs more developers

Possibly so. Feel free to volunteer your time! Visit the forums and Realtime chat, and git repos, and see what needs to be done.

Why is Pop!_OS using all my RAM?

Essentially, unused RAM is wasted RAM.

Many new users notice how the Linux kernel handles memory differently than they are used to. Since accessing data from RAM is much faster than from a storage drive, the kernel caches recently accessed data in memory. The cached data is only cleared when the system begins to run out of available memory and new data needs to be loaded.

We could distinguish the difference from free command:

$ free -h
              total        used        free      shared  buff/cache   available
Mem:           2.8G        1.1G        283M        224M        1.4G        1.2G
Swap:          3.0G        881M        2.1G

It is important to note the difference between "free" and "available" memory. In the above example, a laptop with 2.8G of total RAM appears to be using most of it, with only 283M as free memory. However, 1.4G of it is "buff/cache". There is still 1.2G available for starting new applications, without swapping. See man free(1) for detail. The result of all this? Performance!

See this wonderful article if your curiosity has been piqued! There is also a website dedicated to clearing this confusion: http://www.linuxatemyram.com/

Where did all my free space go?

The answer to this question depends on your system. There are some fine utilities that may help you find the answer.

Package management

See the apt and Pop!_Shop pages for more answers.

I have found an error with Package X. What should I do?

First, you need to figure out if this error is something the Pop!_OS team can fix. Sometimes it is not (e.g. Firefox crashes may be the fault of the Mozilla team); this is called an upstream error. If it is a Pop!_OS problem, there is a series of steps you can take:

  1. Search the forums for information. See if anyone else has noticed it.
  2. If you would like, write a forum post detailing the problem and the fact that you have reported it already. This will help prevent a lot of people from reporting the same error.

I just installed Package X. How do I start it?

If you are using a desktop environment like KDE or GNOME, the program should automatically show up in your menu. If you are trying to run the program from a terminal and do not know the binary name, use:

$ dpkg -L package_name | grep /usr/bin/

Upstream project X has released a new version. How long will it take for the Pop!_OS package to update to that new version?

Package updates will be released when they are ready.
