Sparky 5 based on Debian 10 “Buster” has been moved to the new stable line now.
What you should do now?
1. Check Debian repositories to make sure your OS uses ‘buster’ (or ‘stable’) repos at the /etc/apt/sources.list
2. Sparky 5 automatically changes its own repositories from testing to stable, by upgrading the ‘sparky5-apt’ package:
sudo apt update
sudo apt install sparky-apt sparky5-apt
3. Then make full system upgrade:
sudo apt update
sudo apt full-upgrade
Sparky Upgrade Tool should install the latest ‘sparky5-apt’ package before performing the system upgrade, but if it doesn’t, close the Upgrade Tool and do it manually in a terminal emulator, as above.
If you would like to keep using the rolling edition based on Debian testing:
1. Check Debian repositories to make sure your OS uses ‘testing’ repos at the /etc/apt/sources.list
2. Temporary change Sparky repos from ‘stable’ to ‘testing’ at the /etc/apt/sources.d/sparky-stable.list if your system uses Sparky ‘stable’ repos already, and refresh package list:
sudo apt update
3. Install the latest version of the following packages: ‘sparky-apt’, ‘sparky6-apt’, ‘sparky-core’; the ‘sparky5-apt’ package has to be removed.
sudo apt install sparky-apt sparky6-apt sparky-core
4. Then make full system upgrade:
sudo apt update
sudo apt full-upgrade
Let me know if you find any problem with upgrading your Sparky installation, please.
