After installing pacman packages (last one was ‘ungoogled-chromium’) my root partition of 20GB is completly full. Now I can’t update new packages.

My partition structure is: root (20GB) /home (470GB) swap (10GB)

How can I delete the garbage that is piling up in my root, and how to prevent it from happening again.

    Not sure about arch but one thing I’ve found takes up a fair amount of space is older kernel versions that remain installed

    Run ncdu (CLI) or Filelight (GUI) on your / and see what’s taking up all that space first, then we can figure out what to do about it.

      This realy helped my out. /var/cache/pacman took up over 5GB of space in my root partition. To prevent this from happening again, is there a way to move pacman cache to my home partition where I have over 300GB of space for pacman to consume?

    Just in case you use Docker, you should clean images and containers on disk. They usually live on the root partition and take huge amounts of space.

    check to see howuch space your log files are using.

    to prevent it from happening …

    I would consider 20GB for / to be too small for long term desktop use.

    and with just 470GB for /home, I would not split the two up.

      log files only took up 800MB, but I fixed most of the problems now, by setting up pacman to put the cache in the home partition.

      You are right, it was better to leave /home in the same partition, but now it is difficult to chance that. I thought it had advantages when something goes wrong with my root i can swap it out, but it only caused problems for me. Why do so many people split up there /home then? I thought it was common practice.

        The main advantage of having a /home partition is that you can easily preserve it during reinstalls or during a distro hop. Reinstalls used to be more common in the past when some distros didn’t allow full distro upgrades without reinstalling. See this result which is still ranked #1 on duckduckgo

        I personally use a @home btrfs subvolume which has most of the same advantages to me, and additionally allows @home and @root to share the same partition. It also allows me to use luks on everthing without bothering with lvm.

      Because you don’t need to dd your entire /home partition to a drive, wipe your system drive, then dd your /home back.

    In addition to everything else, if you’re not using hibernate you could reclaim some of the swap partition, 10 GB is completely wasted.

    I would delete and merge the swap space into root if they’re neighbors. You can create swap files instead of any size you want, and place them anywhere you want, like /home.

    I would recommend starting with 1 GB of swap and see how much is actually being used.

    To create and use a swap file:

    • Use dd if=/dev/zero of=/swapfile bs=1M count=1024 to create a file.
    • Use mkswap to format the swap file.
    • Use swapon /swapfile to activate it.
    • Add /swapfile none swap sw 0 0 in /etc/fstab to activate on every reboot.
