I've written a small bash script to help with updating various packages/dependencies on my machine (Pop!_OS) but it doesn't seem to be working correctly for flatpak. If I run flatpak update in the terminal it will show that I have updates, but when running the script there aren't any updates.
The Script:
#!/bin/bash
# Update package list
sudo apt update -y
# Upgrade the packages and dependencies
sudo apt upgrade -y
# Remove unnecessary packages and dependencies
sudo apt autoremove -y
# Clean package cache
sudo apt clean -y
# Update Flatpak
sudo flatpak update -y
# Update firmware
sudo fwupdmgr update -y
echo "All updates and upgrades have completed sucessfully!"
EDIT:
Running flatpak update -ywithoutsudo fixes the issue.
There's something valueable to learn here. Seems like flatpak installs packages per user, meaning when you do
$sudo flatpak update
it runs as the root user, which probably doesn't have any packages installed.
Kind of a weird concept if you used Windows for a long time before switching to linux, where running as admin still used the same user account just with elevated privileges iirc
Edit: According to flathub running flatpak as root installs packages systemwide, otherwise they're installed on a per user basis. You should still keep the multi user thing I mentioned in your mind if you're used to windows
