How to upgrade?

[Skyhawk1207]

Hey team,

I saw that the version 3.0 has been made available on the website. A huge congrats on that! I really appreciate the work you all have been putting in to make the OS awesome.

I am currently using Lingmo 2.1. How can I upgrade to 3.0 without losing my data? Thanks!

For 3.0, you need to do some modification for your apt source!

Here's a summarized step-by-step guide to update your software sources and add new Lingmo sources on a Debian-based system:

1. Check Current Sources:
   • Open the terminal.
   • Enter the command to view your current sources:

     cat /etc/apt/sources.list
     

   • Check for additional source files with:

     ls /etc/apt/sources.list.d
     

2. Remove Old Lingmo Sources:
   • Delete any files or entries within /etc/apt/sources.list or /etc/apt/sources.list.d/ that contain old Lingmo sources. You can use rm command for files or edit the files with nano or vim to remove the entries.
3. Add New Lingmo Sources:
   • Choose one of the following commands to create a new source list for Lingmo:

     echo 'deb https://packages.lingmo.org/lingmo helium main' | sudo tee /etc/apt/sources.list.d/lingmo.list
     

     or

     sudo bash -c "echo 'deb https://packages.lingmo.org/lingmo helium main' > /etc/apt/sources.list.d/lingmo.list"
     

4. Add the Lingmo Key:
   • Download and add the Lingmo key to your trusted keys:

     wget -qO - https://packages.lingmo.org/lingmo/key/lingmo-key.gpg.key | gpg --dearmor -o lingmo-key.gpg
     

   • Move the key to the appropriate directory:

     sudo mv lingmo-key.gpg /etc/apt/trusted.gpg.d/
     

5. Update Package Lists:
   • Update your package lists with the new sources:

     sudo apt update
     

6. Upgrade Packages:
   • Upgrade your system with the latest packages:

     sudo apt upgrade
     

Summary of Commands:

cat /etc/apt/sources.list
ls /etc/apt/sources.list.d
# Use 'rm' or a text editor to remove old Lingmo entries
echo 'deb https://packages.lingmo.org/lingmo helium main' | sudo tee /etc/apt/sources.list.d/lingmo.list
# or
# sudo bash -c "echo 'deb https://packages.lingmo.org/lingmo helium main' > /etc/apt/sources.list.d/lingmo.list"
wget -qO - https://packages.lingmo.org/lingmo/key/lingmo-key.gpg.key | gpg --dearmor -o lingmo-key.gpg
sudo mv lingmo-key.gpg /etc/apt/trusted.gpg.d/
sudo apt update
sudo apt upgrade

Thank you @elysia-best! That's really helpful. I've also noticed there are some new softwares in Helium (like the System Monitor), can you please let me know a list of those new softwares so I can apt install them all?
