I got my Pi in Fall, 2018, and have not had trouble running it. However, when I tried to upgrade my Raspbian back in May, 2019, and it didn’t look like I succeeded because when I issued the command “cat /etc/rpi-issue”, the response was:
Raspberry Pi reference 2018-06-27 Generated using pi-gen, https://github.com/Rpi-Distro/pi-gen, 0d34fb94398a4bd79711f21d6a0b5d35fe5f4a76, stage5
I assume the “reference” is to the “name” of the release and I knew there were releases subsequent to June, 2018.
I got distracted and didn’t try again until today. After several attempts, I’m pretty sure I got the list of updates (sudo apt update) but during “sudo apt dist-upgrade”, my Verizon connection dropped. Even though I did a reboot (sudo reboot), my reference is still June, 2018, no packages download (sudo apt update) and nothing changes with sudo apt dist-upgrade.
What can I do to get the updates to be applied?
Thank you for any help. Diane
