I am using KDE Plasma 6.1 dev, and i have got an update which was around 190 mb , after clicking the update button and restarting the device, still shows to update it, I did this thrice, but it wont apply the update.
Can you try some command line commands to see if they have more output? ``` pkcon refresh pkcon update ``` and paste the output of that or for example ``` apt update apt full-upgrade ```
