After several hours of posting my question here I searched on google and the very same problem with solution had been posted in 2016.
Here is the URL https://blog.gyt.is/2016/03/01/how-to-create-a-new-user-on-raspbian-powered-raspberry-pi/
The solution below is the applicable part to that webpage with just the solution, rather than the background:-
You have to connect as root. So in the "debug application" dialog, in the "connection target" field (where it currently says something like firstname.lastname@example.org) change this to email@example.com. You'll be promted for the root password, which should be the same as for the pi user. If that doesn't work, ask google on how to allow root access by ssh on the Pi. This ...
You could just use
Take option 3
Take option 1
Select command line (I always force logon)
The amount of space taken up by 'X' is very small on the SD and who knows you may need a GUI for something later.
The last time I tried removing the GUI I took out:
But that was before Buster.
You do not ask a question. If it is to have a Raspbian operating system without any GUI elements then just flash the Light version of Raspbian. At time it is Raspbian Buster Light. These images does not have any support of a Graphical User Interface and uses only the command line on a console.
Thank you all for your answers or explanations! Over the last 2 weeks I have started to realize what I am taking on. I am doing small chunks of each steps like suggested in different ways to better get a grasp of how to get everything I want up and running. I have accomplished most of the things. To date I have openmediavault with docker using portainer to ...
Disclaimer: I don't know what caused the problem. It seems that a kernel update might be a culprit. But I am not certain.
Two changes that allowed it to work (this on MATE now): in user config file (which is conveniently on FAT32 partition, so can be accessed from anything) I forced the use of HDMI with hdmi_force_hotplug=1 -- I thought it might have been a ...
That's a big project what you try to implement. This sort of questions does not fit very well to the format of this Q&A. You should split it in different detailed single questions. But I will try to give some general ideas to your project.
You are looking for encapsulating scripts and helper programs in the hope they will simplify setup. This may be ...
You can use a tor proxy that will route all traffic from an interface to the Tor network. You have to configure an access point using your favorite setup. It must work as expected before you will start to setup the tor proxy. Then you use the interface of the access point to route its traffic to the Tor entry point. How to do that you can look at How to make ...
I have just checked your test video and it works fine in the latest Pale Moon, with sound.
Pale Moon browser is a fork of Firefox which supports older Firefox addons (which Firefox dropped after version 52). It is slower than Chromium but requires significantly less RAM, so it can actually outperform Chromium on a system which is short on memory.
Pale Moon ...
I finally got this working.
Started from scratch with fresh install of Buster. Configured the wpa_supplicant.conf by following directions in this post - https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=274194&p=1662955#p1662955 and installed the relevant WiFi driver from here - http://downloads.fars-robotics.net/wifi-drivers/8188eu-drivers/
I don't have an answer, but I may be familiar with the issue that you are seeing with regard to the psutil command not showing the CPU temp correctly. I recently found a possible bug with the psutil command, which in my situation was reporting the temperature of the Dallas DS18B20 temp sensor that I had connected to my raspberry pi's GPIO (as an enclosure ...
The file has to have a few specific entries now. The minimal file contents I have found are:
Can you edit your question and put your file here (redact the SSID and password) via a ...
It is possible that you may be running out of ram. You may want to set the preset ram to a slightly higher number, allowing the server to utilize the ram more efficiently. I have a video dedicated on how to set up a Minecraft Server (only on the Pi 4): https://youtu.be/SBX-90NcAJo
Raspbian is installed on two partitions: a fat32 boot partition for kernel and firmware and an ext4 partition for the root filesystem. To disable password authentication and only use public/private keys you always have to modify files on the ext4 filesystem at least one time. The ext4 filesystem is not readable by MS Windows or by iOS without additional ...
It should not make a difference if you run the root filesystem from a primary partition or from a logical volume. The operating system only sees the ext4 filesystem, no matter where it is located. Because you restore a complete backup of the SD Card to the logical volume there should also not be a difference.
The only thing I see is, that the display driver ...
... but I can't get any info on connecting from a pi
For this reason some times ago I have made a proof of concept but not completely finished it yet. There you will also find how to setup a Raspberry Pi as Wireguard client. This may give you some ideas what to do with your project. Have a look at How to bridge an access point with a remote network by ...
Cortex A72, the arm core used in Raspberry Pi 4 is not on the support list of libpfm.
It seems the PMU of Cortex A72 is similar to Cortex A57, so you can add support for Cortex A72 by duplicating the code for Cortex A57.
Here is a patch I made on papi 18.104.22.168 release, so after clone the repo, git checkout to tag papi-6-0-0-1-t, then git am to apply this ...
Not sure I understand what you're trying to do, but here's the answer to your question:
It seems you may be looking in the wrong place. If you want to learn if a package is available on your RPi, try this:
apt-cache search xxxx
In your case, 'xxxx' is veyon, and so on my Pi w/ buster:
$ apt-cache search veyon
libveyon-core - Computer Monitoring and ...
If the green light is not on there is definitely a problem with the SD Card. The only things you can do are try a different SD card and reformat the one you are currently using. If neither of those work, it would seem to be a hardware issue. In that case it is much more worthwhile to get a new Pi rather than trying to fix it yourself since the Pi is so cheap....
You are doing many things wrong. You have first to update the package list before upgrading them. Then you should better use apt full-upgrade instead of only simple apt upgrade.
rpi ~$ sudo apt update
rpi ~$ sudo apt full-upgrade
Then you use rpi-update that may leave an unstable operating system because its only for testing things under development. ...
Current versions of SIMH don't need setting up tun/tap interfaces in order to be able to use TCP/IP with them, as it provides a nat: network interface that does all the work for you of setting up NAT to work with your emulated machine 
Just attach the guest's NIC as follows:
sim> attach xq nat:tcp=2323:10.0.2.15:23,tcp=2121:10.0.2.15:21
You could try removing the desktop tool and re-installing it:
sudo apt update
sudo apt remove wpagui
sudo apt install wpagui
To start it
My Buster box currently reports:
wpagui/stable 2:2.7+git20190128+0c1e29f-6+deb10u1 armhf
Not sure if this will help or make it worse so please have a backup of the SD card :-)
Try to allow DNS :
sudo ufw allow out 53
For your ping command ICMP rules is also require you can read here.
# allow outbound icmp
-A ufw-before-output -p icmp -m state --state NEW,ESTABLISHED,RELATED -j ACCEPT
-A ufw-before-output -p icmp -m state --state ESTABLISHED,RELATED -j ACCEPT
For error Failed to fetch http://... you need to allow http traffic ...
Eventually it worked after I reinstalled the OS changing it to the regular GUI version from the Lite one. I didn't run rpi-update again since the new firmware had been already installed.
Not sure whether it's because of some issue with the Lite version either just the system needs to be reinstalled after the firmware update but anyway now vcgencmd ...
The error described in my question/issue above was caused by issues of kernel files located in the boot partition. Originally I only backed up the files on the "os" partition of the Raspberry. So if you update the kernel or parts of the kernel and restore the files on the "os" partition, the kernel files on the "os" partition are not compatible with the ...
I use it in pigpio so it certainly works.
Perhaps have a look through the code on GitHub.
I remember needing to declare some structures when the code was first written as the Linux development files seemed incomplete.
It is unclear what you really want:
I just need the ability to connect to the Pi through AP mode and the Pi should be able to contact a website for data
But you are talking about wlan1 that is usually provided by an additional USB/WiFi dongle. You do not need it for what you have written. With a Raspberry Pi 3B+ you can just use the built-in WiFi with ...
I have solved installing the previous version of teamviewer. now it works fine.
First completely remove the old version prompting
sudo apt purge teamviewer
and then get the previous version of teamviewer from the web
now you can install this version typing
Try running the commands as follows:
rfkill list wlan
rfkill unblock wlan
echo "Check that wifi is unblocked."
rfkill list wlan
Just use the command
for an explanation.
Raspbian now uses rfkill to disable wifi if there is no valid country code in /etc/wpa-supplicant/wpa-supplicant.conf. This seems to be a relatively new addition which is ...
Thanks to @Jaromanda X.
Using user in fstab implies noexec, so add exec after user:
/dev/sda1 /mnt/hd auto defaults,user,exec 0 1
However if you do not want to mount with exec flag you can run:
$ sh start.sh
(or another script interpreter).
As the script is just a text file and the interpreter is on another partition (exec-able), it will run.
I cannot follow your specific issue because lack of detailed information about your programs, setup and environment. But I will discuss the additional output you have given. I may not exactly match what you need but it could give you an idea where to look to solve your problem.
In general, systemd can start any service that you can successfully run on the ...
I was able to use PulseAudio to route my audio to the RPi.
The superuser question linked by @user1937198 gave me a place to start, however I wasn't able to publish over ssh as suggested by the article because when I typed in ssh -R ... I was given the ssh usage help:
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec]
I want all audio from any application to go out the audio jack on my raspberry pi, which is hooked to an amplifier. That's all.
On my Raspberry Pi 4B with a fresh flashed Raspbian Buster Light this is working out of the box. I plugged in a headphone into the audio jack and downloaded a small test audio file:
rpi ~$ curl -o working.wav http://hoeft-online....
Thanks to the good advice by Jaromanda X I shared internet through ethernet into my computer. I was able to ssh through that, and when I logged in it said that wifi was blocked because of rfkill. I did not install that package, and I don't know why the service was active by default. All I know is that entering:
rfkill unblock wlan
fixed the problem, and ...
If you have an up to date Raspbian Buster installation with a standard network setup it is portable between all Pi models.
Seeing as the Pi2 doesn't have on-board WiFi there are possible errors and it is Essential that a valid country=XX is included in wpa_supplicant otherwise WiFi will be disabled.
