I want to upgrade the distro from wheezy to (in the end) buster, but with upgrading the jessie it wont past the rainbow screen after the reboot.
I was able to get into the pimusicbox adding legacy entries in the ssh_config.
is it safe to change the entries in cat /etc/apt/sources.list
deb …mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb-src …mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
deb …archive.raspberrypi.org/debian/ wheezy main
deb …www.lesbonscomptes.com/upmpdcli/downloads/raspbian-wheezy/ unstable main
deb-src …www.lesbonscomptes.com/upmpdcli/downloads/raspbian-wheezy/ unstable main
and just run sudo apt-get update followed by sudo apt-get dist-upgrade -y?
