I am unable to update from EndlessOS 3.3.15, but I can uninstall and install the apps. The “No updates available” message appears after I click on the link “Check for updates now” in Settings > System > Details.
I have tried every solution described here, but without success.
Please find attached my diagnostics report.
Looking forward for your answer,
