I had some problems to get my Bluetooth headset working with my Debian, the fault was kind of non informative. In the end I found in some forum that it needs the following lib. libspa-0.2-bluetooth I found this here. Connection Failed: br-connection-profile-unavailable This was the only fault shown in the GUI.
So to upgrade Raspbian, as it was previously called, from Buster to Bullseye went smooth an easy, I tried this with some Pi2B (armhf 32Bit) and with a Pi4. These two are headless systems, so I don’t know if this works well for any systems with window managers. Better run these commands in screen, so when the SSH connection is interrupted you can reconnect and resume your work. Edit: For the update there is a culprit, it will cause a problem with dhcpd, so before the reboot 13. (was point 12. before I added the remark below) please check this post. ...
Add key curl https://ftp-master.debian.org/keys/archive-key-10.asc | gpg --import gpg --export DC30D7C23CBBABEE | apt-key add - The fingerprint (DC30D7C23CBBABEE) given is the one that the first command outputs, which is the fingerprint of the key downloaded by curl. 2. Add repo echo "deb http://deb.debian.org/debian buster-backports main" |sudo tee /etc/apt/sources.list.d/deb_buster_backports.list run apt update/upgrade Install tor, I did this by: apt-get install -o Dpkg::Options::="--force-confold" -y tor
Just some info, because the last time when I flashed an SD card I took #Raspbian only because I could not find the #Debian images as quick. Infos about Debian for #Pi are here: https://wiki.debian.org/RaspberryPi Images: https://raspi.debian.net/tested-images/ Some tips for settings, like #SSH on first boot (you need to add a key): https://raspi.debian.net/defaults-and-settings/
This is a solution for a #RaspberryPi, some #VPS without swap of some machine setup without swap where you need swap for something without wanting to fiddle with the drive partitions or so. This is a quick and dirty “short manual” for #Debian based #Systemd environments (such as #Ubuntu, #Mint or #Raspbian). First run this: cat > dphys-swap.sh << EOF #!/bin/bash #~/up apt-get install dphys-swapfile echo "CONF_SWAPSIZE=2048"|tee -a /etc/dphys-swapfile dphys-swapfile setup dphys-swapfile swapon systemctl restart dphys-swapfile.service systemctl status dphys-swapfile.service free -h EOF This will just create a short #bash #script with the needed commands to run to get #dphys setup and running. Please alter the number 2048 to your need, it is the size of the swap memory that will be setup. The size of the swap should most likely by equal to the real memory installed, sometimes twice the size seems to be a good choice too. ...
I have this small script deployed on any of my #Debian based systems, it just does all the update, upgrade, dist-upgrade, autoremove and autoclean in one run. #!/bin/sh if [ $# -eq 0 ]; then sudo sh -c "apt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get update && apt-get autoremove && apt-get autoclean" else sudo sh -c "apt-get update && apt-get upgrade && apt-get dist-upgrade && apt-get update && apt-get install $@ && apt-get autoremove && apt-get autoclean" fi I have this script deployed in a lazy manner, I just have it sitting in my users home folder and called it “up”, I did do a “chmod +x up” and just start it like this: ...
