Why Choose Arch Linux?

Arch Linux stands out for several reasons:

  • Rolling Release Model: Always have the latest software.

  • .vimrc for Vim editor settings.

4. Troubleshooting Tips

  • Pacman Database Issues: 
  sudo rm -rf /var/lib/pacman/db.lck
Enter fullscreen mode Exit fullscreen mode
  • Boot Issues: Reboot into a live USB and chroot into your system to fix configurations.

I'm using Ubuntu with i3 for its simplicity and I'm really happy with it. Looking back at the time I was using Gentoo: I now need much less time in configuring stuff or fixing bugs. How it's with Arch: do you have to spend lot of time for troubleshooting, or is it just working?
