I had a similar problem when trying to connect to Raspbian Buster and the instructions at the link below solved my problem without having to install a new VNC server.

I haven't completely understood what you have done, but in respect to your own answer it is in general possible to run 32 bit programs on a RasPi running a 32 bit or a 64 bit kernel. You cannot run a 64 bit program on a 32 bit kernel, which is default. For this you must use a 64 bit kernel. Raspbian Buster has a precompiled 64 bit kernel available together ...

By creating that post, I noticed that aarch64 is the crucial part.
I need aarch64-linux-gnu-g++ for compilation and the resulting image will run directly.
It seems that - unlike Windows - 32bit programs cannot be run on a 64bit architecture.

So far the only solution I have found to work is to use the web browser SSL VPN setup on the Fortigate, and then connect using the Raspian (Buster) Chromium browser. You wont have tunnel mode but for RDP, SSH etc it works fine.
For apps that require tunnel mode my workaround is to create a RDP/VNC desktop/jumpbox with supporting software on the network ...

Instead of the command you used to install the server, try this:
sudo apt install apache2 php7.3 mariadb-server mariadb-client php-mysql phpmyadmin
You cannot install multiple packages by seperating their names with &&.

Add the following lines to /boot/config.txt:
# Disable Activity LED
dtparam=act_led_trigger=none
dtparam=act_led_activelow=off
# Disable Power LED
dtparam=pwr_led_trigger=none
dtparam=pwr_led=activelow=off
Then reboot your Pi and both LEDs should be off permanently. Just tried it myself.

Currently there is no package that will run on the Pi.
The packages you are trying to install are for x86 chipsets only.
Best thing to do is move your day to day computing to the Pi and free up your PC or Mac to do the folding tasks.
Edit: Source for the client is not available for cross compilation

Results of a test with a Pi 3 A+, following instructions from here;
Second SD card via SDIO 1-bit
1) Second SD card appears as /dev/mmcblk1
2) Integrated WiFi interface does not appear in ifconfig
Second SD NOT enabled
1) Second SD card is ignored
2) Integrated WiFi interface appears in ifconfig, and is functional
No, you can't have both, they are ...

If i understand you correctly,
you can click on the raspberry Icon in the upper left of your screen.
a menu should drop down, move your mouse cursor down to "Preferances".
a screen should open to the right of your mouse cursor and you need to
re-position the cursor into this secondary menu.
in this secondary menu, move your cursor down until "Recommended ...

@Milliways Comments about NOOBS sent me on a little research expedition that allowed me to fix the problem. Eventually, I found my way to this excellent article on boot problems: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=58151 From that, I figured out that the little lightning bolt on the rainbow screen was indicating a power problem and ...

Have you created a user for Samba (with password) and are you using that to authenticate? The public=no will stop access without the authentication.
Are you 100% sure you have the correct IP address?
You could try adding
server min protocol = SMB2
to the global section of your config file
Also check the rights on the mount point - its possible they are ...

I do not follow the link you have given, tl;dr. But it seems that it uses the method to download wireguard from the Raspbian testing version Bullseye and install it on the current Raspbian stable version Buster. Doing this, it is needed to compile the kernel modules for wireguard so it fit to the Buster kernel. Because you run into problems, it seems that ...

You need a stereo audio amplifier between the Pi’s analogue audio out and your speakers.
If you’re ok soldering something like the following should work and could be powered from the Pi’s 5V.

I answered your question according to "what you expect to do".
Honestly, it's not a good idea to show the camera stream over a remote desktop tool like VNC. You should improve your code to stream the camera over the HTTP protocol to create an RTC connection. You could do it with the help of OpenCV on python.
Although, I suggest you install the motion ...

I had a similar issue with my Pi. Doing a simple pip install solved the issue.
pip install RPi.GPIO

I am using X11 forwarding on the raspberry and putty on windows. This way you can see the display of the raspberry on your laptop. I haven't had issues with it. To set it up you need to enable ssh in raspi-config.
Then edit
sudo nano /etc/ssh/sshd_config
and uncomment the line
X11Forwarding yes
install xming and putty on your laptop and set up putty under ...

ssmtp has been deprecated in Buster
In general following ANY 5 year old post is at best an exercise in optimism

The Raspberry PI 4 uses a Quad-core ARM Cortex A72 processor while the Raspberry PI 3+ uses a Quad-core Cortex A53 processor. The A72 processor is a newer version (2016) of the ARMv8-A architecture than the A53 (2012).
The A72 uses out-of-order and speculative execution and other improvements to achieve better performance than the A53.
This is analogous ...

So to wrap this up I tried a few things that improved performance a lot.
As suggested by Milliways, using some form of non-blocking sleeping function reduced the CPU usage a lot.
After using fprintf(...) I use fflush(...). That also reduced the times when an OS call would somehow intervene.
Running the logger in its own thread helped separating hickups in ...

There are a combination of factors involved, but without seeing your code it is difficult to be specific.
c buffers output internally until its internal buffer is full.
The OS caches disk I/O and will only perform actual I/O in blocks on
an as needed basis.
The OS is multi-tasking and allocates time slices to many tasks so
the actual execution time is ...

Writing to a file in Linux typically doesn't result in a write to the device. Written data end up in cache (RAM) and are eventually propagated to the SD card.
If you need more deterministic timing, write your own caching function. If your logging thread only ever writes to RAM (and a separate low-priority thread transfers that to the SD card), you will have ...

Linux is a multi-user, multi-tasking operating system. Something else might have needed the SD card (logging?) or CPU time.

Installing desktop envirnonment will solve the problem
To install XFCE, enter the following command:

Unfortunately, I still could not get systemd-networkd to connect to the main network no matter the driver that was being used. I did find another solution entirely, however, that seems to have worked. I installed this modified ubuntu-mate image that supports the 3B+ and then used the built-in hotspot function on ubuntu to generate the access point. Ubuntu-...
