+ DietPi-Pre-patch | Re-apply suite change patch on Buster, since it is not accepted by default on "apt" package versions below 1.8.2.3 by default. Use the "-o" option now which allows automated acceptance as well on Stretch.

@@ -8,6 +8,7 @@ Changes:
 - DietPi-Login | The DietPi banner on login won't be shown anymore if ~/.hushlogin exists, which is a common method to prevent the shell from printing /etc/motd on login and should hence be respected for the DietPi banner as well. Many thanks to @dnknth for doing this suggestion: https://github.com/MichaIng/DietPi/issues/4786
 
 Fixes:
+- General | Since the Armbian repository router does not reliably preservers HTTPS on redirects yet, APT by times fails, when detecting a downgrade from HTTPS to HTTP. We hence change the armbian.list to use plain HTTP, until the issues with the router have been resolved.
 - DietPi-LetsEncrypt | Resolved an issue where the script failed when ownCloud or Nextcloud are were installed. Many thanks to @billouetaudrey for reporting this issue: https://github.com/MichaIng/DietPi/issues/4752
 - DietPi-Software | Resolved an issue where software services failed with a cryptic error message, when an expected directory was not present. This was especially reported with Sonarr and Radarr, if their log directory was missing for some reason. When directories are missing, which are explicitly listed to be read-writeable within the systemd service, systemd prints "Failed at step NAMESPACE spawning", while Sonarr and Radarr themselves would print a clearer error message about the missing log directory. Many thanks to @stevewitz for reporting this issue: https://dietpi.com/phpbb/viewtopic.php?t=9463
 - DietPi-Software | Lighttpd: Resolved an issue where the upgrade from Buster to Bullseye, following our guide, fails if HTTPS was enabled via DietPi-LetsEncrypt before. Many thanks to @fhals for reporting this issue: https://dietpi.com/phpbb/viewtopic.php?t=9477
