A few days ago, I upgraded to a new kernel. Unfortunately, before the installation was finished, the computer froze and I had to restart it forcefully.
Now, in GRUB, it shows the new kernel and below it a "Previous Linux versions" item. Whenever I boot into the new kernel, I get my screen flickering. Several daemons start, but it freezes there; it never gets me to the display manager.
Fortunately, the items under "Previous Linux versions" work. From there, I want to reinstall the new kernel. I tried from searching in the /var/cache/apt/archives/ directory and installed all the kernel related files there; that didn't work -- I still get the new kernel version that doesn't work and the Previous Linux versions item. I tried through Synaptic, the results were the same. I ran sudo update-grub, but that didn't do anything
How can I upgrade my kernel to the newest version and eliminate the "Previous Linux versions" item?
I am using 11.04 with amd64 architecture.
