Oracle not starting after system reinstallation

After formatting root partition and installation of Xubuntu 8.10 instead of Kubuntu 8.04 (but preserving /home) Oracle failed to start:
oracle[SID]: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory
ERROR:
ORA-12547: TNS:lost contact


Enter user-name:

The solution was to install libaio1:
sudo aptitude install libaio1
Well, somewhat natural consequence of the decision not to automatically reinstall all the packages present in my previous Hardy installation...
