Programs

Install, Uninstall and Purge are the three defaults for program command line arguments. Purge is a deep clean remove which can be useful if there is some problems removing all the little parts of a program.

sudo apt-get install <program name>
sudo apt remove <program name>
sudo apt autoremove --purge
sudo apt-get --purge remove <program name>

Sound Issues

‘Turning it on and off again’ is sometimes the greatest advice for Linux sound issue tech problems.

sudo alsa force-reload

Flush DNS

sudo systemd-resolve --flush-caches
sudo systemctl restart nscd.service
sudo systemctl restart named sudo
systemctl restart dnsmasq

Boot to BIOS

systemctl reboot --firmware-setup

Boot to Recovery

If your PC is failing to boot. Such as having a headers error message (like vm-linuz) you can use this when your BIOS screen is loading to get into Pop! OS recovery.

ctrl + alt + F1

Fix Boot Partition

dpkg -l | grep linux-image
sudo apt remove --purge linux-image-(numbers here)-generic

You can also see their numbers in Disks.

You can go into nautilus (root, then type in nautilus to enter nautilus) > Boot, to delete them manually also.

Repair Filesystem

Only use these codes prior to the OS from booting, such as in Gparted to repair your filesystem. Change sd1 with your fsck -l drive’s code.

sudo fdisk -l
fsck /dev/sda1
sudo fsck -f /dev/sda1

Flatpak and Snap

List Flatpak or Snap installed programs.

flatpak list
