Did you remove previous entries from apt.conf before switching? You got the
wrong kernel version, and you got that error because python library expects
a different glibc version.
It seems like you have a bunch of different packages installed altogether.
What are the contents of your /etc/apt/apt.conf? And what does dpkg -l
libc6 and dpkg -l linux-image* show?
