I have a virtual machine of Sparky5 KDE 64 bit and when I go into updating it in terminal on start up often times it will give a 2 line error message on
"apt full-upgrade -d" that says apt is busy. And I can repeat apt update and watch the numbers of programs to update decrease. I note that the sparky upgrades do not occur automatically.
I tested and this occurs even when I go to tty1 (via (right) Ctl-F1 (as it is a virtualboxen).
I looked around the web awhile back, no luck. Again today.
I have looked around in preferences - especially in background services
https://superuser.com/questions/1322624/turn-off-automatic-updates-on-debian-kde5 ##They can not find anything either
Debian forums, no luck, I have followed a Sid forum for years and have not seen anything there either.
So if any one knows, I would appreciate.
I am preparing to transfer my stable system to buster in a month or two and I was thinking of going to Wayland, but "never-gnome" for me, and sway is not stable enough for me. KDE is often a bumpy ride in testing (and pure chaos at times in Sid I see) but it would be all right for me in Stable. But not if it auto-updates on me, I like to control all updates. peace out.
If anyone knows
EDIT : Days later.
It was a little glitchy, back and forth for getting it to save in Discover. I was not sure. So I logged in over the course of several days, and updated and let it sit for hours, no auto-update. Thank you very much lami07 .
KDE Plasma has it own software center/updater called Discover. You can disable/modify it's autoupdate feature there.
