Re: PiScope Installation Problem

Most likely cause is that pigpiod is already running.
It's normally activated through raspi-config (or its GUI version)

If that's the case then you don't have to start it manually.

Re: RPI3 B >>> Mariadb >>> E: Unable to correct problems, you have held broken packages.

To install Mariadb: (i downloaded and extracted successfully to /opt) then.. apt-get update && apt-get install mariadb-server So you're on Stretch but downloaded a non-Stretch version from somewhere? (Raspbian Stretch version is 10.1) Why? And did you also download the newer version's dependencies?

Re: Shell script won't run just edit

Did you make the file executable?

Code: Select all

chmod +x createdirectories.sh
BTW: do you really need to run that script as root? It will set 'root' as the owner instead of user 'pi'

Re: Fake Pi Cameras

These have been around for years.
I would class them as clones, not fakes.

Note that you will only find v1 cameras. RPF added encryption to the v2 camera and so far that has not been beaten.

I had similar issues when I switched from a raspberry pi 2 to a 3. Seems the "official" power supply is not strong enough to run the rpi 3
Irrelevant for the OP's issue. In this case the sd card had insufficient disk space.

Most likely you forgot to update the list with available packages

Code: Select all

sudo apt-get update
before trying to install the program

A quick check confirms that current version is of these files is 'deb8u3' but apt-get requests 'deb8u2'
