Raspbian Stretch (all 3 versions) works on ALL model Pi, have published checksums, and is maintained - at least until superseded by Buster (and for some time after).
NOTE There is no such thing as a Pi 1.
The initial releases were Raspberry Pi Model A & Model B.
There was a Raspberry Pi Model B Rev 2 and later releases increased memory to 512MB
I have ...
I don't know what repositories do you have addressed in your /etc/apt/sources.list. But it seems you have a Raspbian and a Debian repository addressed. This is not a good idea except do you really know what you are doing (sorry, but it seems not to be the case ;-).
The Permission denied is to the remote web sites raspbian.raspberrypi.org:80 and archive....
Your question is unclear.
You can install Vivaldi from the repository with apt install vivaldi-stable
If you want to install the latest from deb use dpkg -i
The version you seem to be trying to install is rather old.
On my system I have, although there is a (very recent) later version.
apt-cache policy vivaldi-stable
I will show a solution in two steps using systemd-networkd. First I create an access point (wlan0) and bridge it with the wired connection (eth0). Then I configure routing between the bridge (br0) and the up-link (eth1).
For reference I use Raspbian Stretch Lite 2019-04-08 updated with sudo apt update && sudo apt full-upgrade && sudo reboot ...
netstat -s and ip -statistics will give you a lot of raw data, but you may need to parse it, and accumulate it yourself. You might want to consider one of the many utilities designed to handle the parsing and accumulation for you.
One such tool is vnstat. It's available for RPi, it's reasonably easy to use and it can be run as a regular user (i.e. no sudo ...
It is inadvisable, and violates the recommendation in PEP 394 to make python refer to python3.
Doing so (by ANY means) risks breaking your system and any tools which use python2 are likely to fail.
If you want to use python3 invoke it with python3.
If you want to install Python 3.7.2 in addition to the default Python 3.5.3, by all means use update-...

Specifically Raspbian checks the contents of the boot directory for a file called wpa_supplicant.conf, and will copy the file into /etc/wpa_supplicant, replacing any existing wpa_supplicant.conf file that may be there. The file in the boot directory is then removed. This can be used to ...
Maybe a bit late, but this could help some other persons...
I ran the same issue.
To solve it, I use the following links:
Make sure the driver for your scanner is selected (files net.conf and usb.conf in /etc/sane.d directory ==> Message #9 ...
Debian is a popular Linux/GNU distribution (Linux is the base operating system, GNU provides applications software packages).
When the Pi first came out there was no Debian variant to support hardware floating point for the old CPUs used in the Pi.
Raspbian was created to allow for hardware floating point and is based on Debian.
The Foundation ...
Preferably you should not change that code at all.
It is intended that you import the module into your own script.
If you see something like
if __name__ == "__main__": in a module that sort of implies the module should be imported and the author has added some example code in the module (after those lines).
I suggest you create a new file called my-test....
Hmm.. not really a question belonging to Raspberry Pi. But here a short answer because I can't put it into a comment. I manage "mixed" locale settings by its environment variables, e.g. in ~/.bashrc. For my special German settings I use:
rpi ~$ locale
How can Rpi send text strings to HC05?
I once wrote a couple of python functions to do the following:
Reset HC05 to AT command mode,
Reset HC05 to connection mode,
Write AT command to HC05,
Read reply from HC05.
With these set of basic functions, I can then do the following.
Set HC05 to AT command mode
A child process of kodi still has control of vt 1. Just doing pkill kodi orphans the child, but doesn't kill it. The screen goes black because kodi is effectively half-dead. Killing kodi and all its child processes will return you back to the console.
The situation for emulationstation is similar - killing all the children will solve the other issue. ...
remove the rpi memory card, plug it into computer and mount the root partition
go to /home/pi/RetroPie/splashscreens/
remove the video file
unmount the drive, return the memory card to rpi and boot it
The video should be gone and the rpi should boot again.
When using the video splashscreens be sure about video format, check more info about it at Adding a ...
