Upgrading to Ubuntu 12.04? Do you really wanna do that? :-p

Yesterday, I decided to upgrade my Ubuntu 11.10 to Ubuntu 12.04. I just wanted to have a feeling of how it feels. But today I just realised that it was one of my big mistakes (well, I am exaggerating), which costed me one full day of searching and hacking back my system.

The screen shows similar to the following line:
...GLIBC_2.14 not found (required by /lib/libply.so.2)...

After browsing and reading a whole day, I got this recipe:
1. On the prompt line, run this:
# mount -o remount,rw /

2. On the prompt line, run this:
# dpkg --configure -a
Some guys suggested to run this over and over again.

3. I think I also ran this:
# fsck

4. Then I remember that I also ran this:
# apt-get -f install

5. Finishing off and reboot the system. If it asks to fsck the system, just follow the instruction on the screen

6. I think that's all and I got my previous Ubuntu 11.10 back online.

This is my personal note which may not be applicable to the reader's system. :-)
