Elementary OS 7: Upgrade from Elementary OS 6.1 - How to upgrade online without reinstallation
In this video I show step by step how to upgrade online and without reinstallation from Elementary OS 6.1 to Elementary OS 7. We're following the Debian upgrade path here, not the Elementary OS developers' recommendation of doing a clean install.
Therefore, the tip, make a complete backup of your data beforehand and know that everything is at your own risk. But it worked for me in several systems.
All Commands:
Prep:
Update OS 6.1 system and reboot system
sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y && sudo apt autoremove -y
sudo reboot
Upgrade:
sudo -i
cd /etc/apt/
vi sources.list
Change the entry focal to jammy
:%s/focal/jammy/g
cd /etc/apt/sources.list.d
sudo vi elementary.list
sudo vi patches.list
Checks:
cd /etc/apt/sources.list.d
grep focal *
grep jammy *
cd /etc/apt/
grep focal sources.list
grep jammy sources.list
Upgrade OS 6.1 to 7:
sudo apt update && sudo apt upgrade -y && sudo apt dist-upgrade -y && sudo apt autoremove -y
Post Processing:
Install Pantheon Tweak Tool (optional if necessary).
Include the PPA:
sudo add-apt-repository ppa:philip.scott/pantheon-tweaks
Pantheon Tweak Tool installation
sudo apt update && sudo apt install pantheon-tweaks -y
Remove Firefox Snap
sudo snap remove firefox
Remove Snap
sudo apt purge snapd ubuntu-core-launcher squashfs-tools
rm -rf ~/snap
sudo rm -rf /snap
sudo rm -rf /var/snap
sudo rm -rf /var/lib/snapd
sudo apt-mark hold snapd
Add Flathub
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flat...
Add Mozilla PPAs
sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa
sudo add-apt-repository ppa:mozillateam/ppa
Install Deb Pakckge Firefox
echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
sudo apt install firefox -y

sudo reboot
And now it is time for you to enjoy your Elementary OS 7 Horus system. :)
