Re: apt is broken and cant find any solutions

You could have tried aptitude, even from the command line, to update , upgrade and install packages. I would suspect that the specific library that caused the failure could have been down or there could have been a filter blocking your access to it. Many times I have found waiting some hours or even...

Re: How to force quit a program / the system?

Mac's have the Opt key instead of the Ctrl key.

To stop a running program, make the program the focused window and use the key combination of Alt + F4 keys.

Re: Can’t access Rasbian boot partition on SD card

You can edit the Pi's configuration by using the SD card to boot a Pi computer and then use the raspi-config to enable the SSH interface. Unless you are logged in as the "root" user, you cannot directly access the root directory. You need to use "sudo" command to edit a file in the "/root" directory...

Yes you can. The Polaris OS is Raspbian with some additional software and different repositories. You can search the RPF repositories for Pi-Top and there will be a return item that can be installed. There is a reason that Polaris is freely downloadable and uses the GPL licensing.

No, it is April 1st there. Kiritimati is 13 hours ahead of London, not behind. When it is midnight in London on April 1st, it is 1:00 pm April 1st in Kiritimati or it has been April 1st for 13 hours there.

At the time of writing (approx 08.00 hrs BST on Sunday 31st March in the UK) I don't think the date has rolled over to April 1st anywhere on the globe yet.
Kintimati, Christmas Island has a timezone offset of +14 from UTC while London on BST is only +1. That is a 13 hour time difference.
