Pi Setup Dec 2018 - Stretch
Decided time to switch to new os and Python 3, this is more or less a log
- 1 Download ....
- 2 Setup
- 3 Remote Desktop VNC
- 4 software installed with package manager
- 5 Share Net Drive
- 6 Clone a Copy for Further Use
- 7 Get Python 3.6
- 8 Change Terminal Colors
- Raspbian - Wikipedia Some info on versions, I took the latest from: Download Raspbian for Raspberry Pi I got RASPBIAN STRETCH WITH DESKTOP
Use this for install directions
said use etcher so that is what I plan to do.
at some point may want a flash drive instead of sd card
next look at:
- look at preferences from menu and enable vnc
- in preferences set the localization to yours
- Before installing new application or service in Raspbian, make sure to always type this into terminal: ( if this file is on your PI use cut and paste ) This takes awhile ( perhaps an hour? )
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade
You many find the following of use as well Linux Commands On Pi
later you may use
sudo apt-get clean
apt-get clean find software packages that are obsolete or not needed in your system and removes them. That results in a cleaner, more performant, and better system. That's good.
And I found this as a complete update: apt - How to install updates via command line? - Ask Ubuntu
sudo apt-get update sudo apt-get upgrade -y sudo apt-get dist-upgrade -y sudo apt-get autoremove -y sudo apt-get autoclean -y
In any case when done reboot.
Lots of update links:
- apt - How to install updates via command line? - Ask Ubuntu

Remote Desktop VNC
- vnc -- turn on use the preferences -- if we could ssh in perhaps we could set up never using a local display, keyboard .....
Default login. Username: pi. Password: raspberry. So, type pi, enter, raspberry, enter. Unless you have changed it.
From now on you can use the keyboard, mouse and screen of your pc. You will need the vnc viewer and the tcpip address of your Pi.
Static Ip Address
sudo leafpad /etc/dhcpcd.conf
Scroll all the way to the bottom of the file and add one, or both of the following snippets. Depending on whether you want to set a static IP address for a wired connection or a wireless connection eth0 = wired, wlan0 = wireless. You’ll need to edit the numbers in the snippet so they match your network configuration.
- interface = This defines which network interface you are setting the configuration for.
- static ip_address = This is the IP address that you want to set your device to. (Make sure you leave the /24 at the end)
- static routers = This is the IP address of your gateway (probably the IP address or your router)
- static domain_name_servers = This is the IP address of your DNS (probably the IP address of your router). You can add multiple IP addresses here separated with a single space.
- my next Raspberry Pi 182/183 I just pasted this into the bottom of the file
interface eth0 static ip_address=192.168.0.182/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1 interface wlan0 static ip_address=192.168.0.183/24 static routers=192.168.0.1 static domain_name_servers=192.168.0.1
then sudo reboot to try it out - ivp 6 may be a good addition to look into
finish get wifi working
above does part of wifi, but need more -- which is to select wifi using the icon upper right of screen. May be a config file way to do it but have not found a reference that seems accurate for this os.
software installed with package manager
spyder3 arduino stuff
did not show samba but
sudo apt-get install samba
showed it was there -- not this time it did a big install ?? did it remove and install, the mysteries continue
>>> create mount point
sudo mkdir /mnt/share1
this gave read access
sudo mount -t cifs -o guest //192.168.0.170/share /mnt/share1
read write with this
sudo mount -t cifs -o username="russ",password="passwordhere",workgroup="MSHOME",file_mode=0777,dir_mode=0777,nobrl //192.168.0.170/share/_Source/rPi /mnt/share1
Make automatic with fstab
2.2 Password Protected Share sudo mount -t cifs -o username=yourusername,password=yourpassword //WindowsPC/share1 /mnt/mountfoldername 3. Now to check that its mounted , run the following command $ df -h
2018 Note: cannot get this to work any more, only guest mount above, working today
- using fstab this will let you auto mount
for nano ctrl O writes a file
sudo leafpad /etc/fstab sudo nano /etc/fstab
note that fstab may be hidden file >> //192.168.0.170/share/_Source/rPi /mnt/share1 cifs user=russ,pass=<password_notin_quotes??>,_netdev 0,0
this looks good for stab
# For Guest Login //WindowsPC/Share1 /mnt/mountfoldername cifs guest 0 0
For Password Protected Login //WindowsPC/Share1 /mnt/mountfoldername cifs username=yourusername,password=yourpassword 0 0
//192.168.0.170/share/_Source/rPi /mnt/share1 cifs user=russ,pass=squeak13,_netdev 0,0
If you make a new entry in fstab it will not auto-mount. Therefore you must reload / refresh the entries. A reboot will do this but that is not a friendly way to do it. A quick way to reload new entries in /etc/fstab (fstab) is to use the mount command:
Spyder says:You have missing dependencies!
rope >=0.9.4: None (NOK)
Please install them to avoid this message.
ImportError: No module named 'pyperclip'
ng: sudo conda install pyperclip -- conda not installed, on windows part of spyder, apparently not here ok: sudo pip install pyperclip ok: sudo pip3 install rope
Update a file but which? Various suggestions include
- sudo leafpad ~/.config/lxsession/LXDE/autostart would be a new file on my system, this may be outdated
- sudo leafpad ~/.config/lxsession/LXDE-pi/autostart does exist so I will try it. -- and it worked added "python3 /home/pi/autoexec.py"
- - by editing /etc/rc.local in my case the line added looks like this: su - pi -c kodi -- I have not tried this
since i cannot get fstab to work this is where I do my share
Clone a Copy for Further Use
pi now has a utility for this that is supposed to even go from a large sd to a smaller one ( as long as the stuff fits )
Some step by step:
- Identify the source os: How To for Raspberry – Checking the Raspbian version (update & upgrade) – Meccanismo Complesso
there should be a file....
cat /etc/os-release .... or .... uname -a .... or .... .... or ....
- Start with a Pi that you want to copy
- You will need a second sd card drive for the clone of the os, it will be wiped
- Bring the source up to date -- run the update steps above.
- Identify the old dirve: f -Bm will show it and its disk usage
- Identify the new drive how? Plug in and it will ask to open a file manager that goes to the mounted card at: media/pi/xxxxxx
- Run utility. Menu -> Accessories -> SD Card Copier
- Put new os in a RPi ( can even use the one used for cloning )
- Fix the tcp ip address so it does not conflict.
Get Python 3.6
- Most methods I have tried are not very satisfactory. Including building from source.
- What did work?: berryconda which also gave me conda and pip useful install tools. Link: tbd
Change Terminal Colors
- Still need to figure this out, but default colors can be really hard to read over VNC viewer.
