Re: Unable to locate package libmariadb3

@rpdom
Thank you. It had not registered with me that Buster was a replacement for Stretch, as I thought that Stretch was the latest.
I will try what you suggest.

Unable to locate package libmariadb3

I am trying to load MotionEye to use for CCTV but I am getting the above error.
I have read that this may be because my Python 3 image is outdated as libmariadb3 has been added recently.

Could someone advise if this is likely and if so, how to get around the problem.
Thank you

How do I print without spaces

I have a Python 3 program that Prints out a date that I have stored in a variable. I would like to print with brackets it like this, (2019-06-29). However, it always prints like this, ( 2019-06-29 ) with a space between my brackets and the date. The only problem I have are the spaces. Can these spac...

Re: WiFi - Hot Spot Access

Thanks but there will be no Physical access to the Pi, in the application I have planned. VNC is essential and I use it daily on 4 other Pi's and it is extremely good in my opinion.

Hiding and Replacing items in tkinter

I am using Python 3. I have used tkinter reasonably successfully (using the grid command to locate items) in that I can draw and delete lines etc using the 'tag' command. However, is it possible to replace those deleted items, as I need to be able to remove them temporarily. I realise that it is pos...

Re: VNC Display

I had initially hoped that the solution would be easy - but I had not expected it to be that easy!
A simple click to toggle the icon indicated by your blue arrow to the 'scale to fit' setting as you suggested was all that was needed.

Thank you very much.

Re: VNC Display

@scruss
Thanks.
It did occur to me that it may not have happened before but I thought surely that was unlikely.

When you say Raspi config, I have been editing the /boot/config.txt file, is that what you mean?

Re: Changing the colour of a tkinter button

When I first introduced the buttons for each day, I was quite pleased with my programming, because I did not draw them all individually and I used the following code. These lines were used near the start of the program dayy = today.strftime ('%w') dayname = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'...
