Forget NOOBS use PINN
this has a much wider choice of OS - you can install any of the 3 versions of Raspbian.
Each OS has to be downloaded from the web, so PINN doesn't waste the 1.3GB that NOOBS does.
Are there options raise and lower the priority/speed of normal background sync
If you read man 3 sync, you'll notice "The writing, although scheduled, is not necessarily complete upon return from sync()", meaning the kernel makes this determination. While fsync(3) does block until completion, the priority of the request will remain the same.
This probably ...
You are asking to delete the unneeded and malformed file "/etc/apt/sources.list.d/brave-browser-release-.list". On the command line just execute this command:
rpi ~$ sudo rm /etc/apt/sources.list.d/brave-browser-release-.list
Switching from the Lite to the Graphical edition fixed the issue for me. I'm sure someone with more command-line configuration knowledge could fix it, but apparently something was missing in the Lite version.
The Raspbian project does not build nonfree packages. Some nonfree packages are available, but they're just the cross-platform ones imported from upstream Debian.
If you need to install it you'll have to build it from source.
As you are told by systemd:
zfs-import.service is not a native service, redirecting to systemd-sysv-install.
Old style SysV init system is deprecated and not used anymore. For compatibility it is only emulated by systemd but there are limitations. Look at Compatibility with SysV.
If you encounter problems with SysV emulation then the first step should ...
If your goal is to only get security updates unattended, without updating all the packages, you need to point to Debian, as Raspian does not maintain a separate security distribution. If you point to Raspian you'll update everything which is more likely to break something.
As to the question of how safe it is to have truly unattended security-only updates ...
Finally i was able to find an alternate way to enable ssh. I will try to summarize it here. I tried PiBakery also but it was too heavy with nodejs and keeps on crashing in every attempt.
The problem: Ext4 format is not readable form windows
So once you burn Raspbian through any img burning tool it creates two partition Boot & rootfs. The boot partition ...
Simple answer - you can’t.
The Mac doesn’t have an X client, although there are options to install one (which is off-topic).
Viable options are to use RealVNC to display a virtual screen on the Mac or run a tkinter program on the Mac remotely accessing the Pi.
Tkinter is an X Window System application and needs an X Display to show itself on. In X Windows you can specify a local or remote display using the DISPLAY environment variable or -display parameter. How you do this depends on your system but if you want to display on the local display it needs to be running a desktop session and you need permission (...
There is no officially supported upgrade.
Expert users can upgrade, provided they are prepared to handle the issues.
If you did this when Stretch was introduced, it may have worked, but there have been significant changes since.
Don't bother! Buster will be out in the next few months.
Incidentally the link you posted contains some very bad advice to run ...
In case, you end up on this route of finding the device path of your USB scanner on your Raspberry Pi, you may want to make sure that the device is able to register as a keyboard (this is how most usb scanners do). Using dmesg helps to see what is really happening here.
In my Pi, the under voltage was making the USB scanner re-register very frequently. ...
⚠ Please read the code before using it because you can lock your USB mouse or keyboard. Add a whitelist of your known devices maybe before running it directly.
I found and modified this script base enough time ago. Maybe you could adapt it quite easily to Raspbian (Edit: I have do it for you finally) and your needs (Edit: but not that).
1) ~$ sudo nano /...
There is no standard ll command. Often there is an alias that defines ll as ls -l.
The output in your question is not from ls -l.
It seems that you have typed ll ../pi/ at the shell prompt and then pressed the Tab Key. This resulted in the display of the available completions. This is a function of the shell and doesn't check whether a command ll is ...
Trying to use two SPI busses on RpiZW
Put a line on /boot/config.txt to enable it "dtoverlay=spi1-3cs"
I googled and found that it is as easy as you say, add one line in
/boot/config.txt. - "dtoverlay=spi1-3cs"
However I know that the dtoverlay thing works for one Rpi model and
raspbian version may not ...
At the very least you will have to enable the CTS and RTS GPIO. You will then have to connect those GPIO to the external device.
CTS is available on GPIO16.
RTS is available on GPIO17.
For UART 0 (I guess ttyS0) you will have to place those GPIO in mode ALT3. For UART 1 you will have to place those GPIO in mode ALT5.
See page 102 of BCM2835 ARM ...
So apparently the only problem is that the lirc drivers are outdated and not present in newer versions of raspbian. Just change that to the new gpio-ir-tx driver and all will work fine. Also note the syntax for the pins changed slightly. I.e, this is what you need in your /boot/config.txt
Yes it is possible to launch Tkinter Python program to the Pi console. What you have tried should have worked. However, if python /home/pi/guiprog.py has a end, a window will appear and run the program to the end and then close the window before the system completes the boot. A good test would be to have a lxterminal and execute the command python /home/pi/...
You can run a tkinter script with just a window manager and XORG, no desktop needed:
Make sure XORG and openbox are installed.
Create the following file in the directory with your tkinter script (named starter here for example purposes):
openbox --config-file ~/.config/openbox/rc.xml --startup tkinterscript.py
Make that file executable ...
WittyPi2 on Pi Zero W Raspbian Stretch - I2C read / write fail
The Pi can do one round of shutdown/start-up, but after this point the I2C errors begin.
However, this works absolutely fine on my 3B.
Well, if WittyPi2 works well with Rpi3B but not RpiZero stretch, then the problem is with RpiZero.
The WittyPi2 user guide ...
It seems like Plex was doing something in the background and used way too much memory. I have reviewed every setting, removed automated preview/cover generation and automated library scanning. Since then I did not experience freezes like this.
