Ubuntu: How to repair Ubuntu installation after broken dist-upgrade without losing any custom settings?


During my attempt to upgrade the Linux installation with...

sudo apt-get dist-upgrade  

...I made the mistake to interrupt the process by closing my laptop, which caused it to suspend to disk. After re-opening the monitor remained black, so I was forced to reboot the system. Until today I discovered many failures of drivers (wlan0 missing, USB memory stick cannot be mounted, USB mouse not recognised, and maybe more undiscovered problems with hardware). My beginner's attempts to manually repair the single problems could make it even worse. During the installation of the current distribution I've chosen to encrypt my whole hard disk.
