Re: How does raspbian buster check for date and time without NTP

Since Stretch Debian/Raspbian uses systemd-timesyncd instead of ntp.
It consists of a service file and an executable.

Google the name to find more information

Re: Kernel updating and Stretch being bumped to 4.19.57

How should the kernel be updated on Raspbian? Raspberry Pi docs say to use rpi-update, https://www.raspberrypi.org/documentation/linux/kernel/updating.md No, it doesn't. It says If you use the standard Raspbian update/upgrade process (found here), this will automatically update the kernel to the la...

Re: CIFS mount not working on Buster

Any suggestions?
reboot your Pi.

Notice that you're still running 4.19.50 but the 'find' sees the files in 4.19.57
I think new kernel was installed in the last update/upgrade and you did not boot your Pi after that.

Re: Desktop preferences not saving changes on RPi4 with Buster

Does your SD card retain *any* changes?
Create e.g. a new text file in your home directory, then reboot.
Is the file still there with the same contents?

Well, that's not very informative...
You could try to start the program manually (on the command line) and see what the output is.
Or maybe it creates a log file?

Re: When does Amazon recieve the new Raspberry Pi's?

So all Pi stuff will be third party. Most of it, yes. But they also sell Pi themselves: https://www.amazon.co.uk/gp/product/B07BDR5PDW/ref=ox_sc_act_title_1?smid=A3P5ROKL5A1OLE&psc=1 Dispatched from and sold by Amazon. I assume they just buy from Element14 as other (non-official) resellers would do.

Re: Can't access package outside virtual environment from inside of virtual environment

Which virtual environment software do you use?

I use virtualenv and it has the option to use globally installed modules.
Can't remember the exact option though.

Buster was just released it went from "testing" to "stabe".
I think you just need to do an "apt upgrade" and answer yes to change the release type.

When NOOBS 3.1.1
Once NOOBS is installed it is never automatically updated.
NB: NOOBS is just the OS installer / selection program.
Are you actually referring to Raspbian? If that's the case then you have to post the command you're issuing and the *full* error message.
