FINALLY worked! :) (for the first time ever with quantal!) I tried about 2 hours shutting down manually. Stopping, starting init scripts, networking etc. I found this only way, and it was to be done exactly in this order. Contra: I have not yet figured the problem out exactly. I think many commands are not mandatory. Now it would be the time to sort them out. I wrote a pseudo log file. Out of my bash history. I'm not an expert, but I really hope you get the idea: >>"(NOTE: DONE BEFORE: sudo apt-get remove --purge modemmanager COMMENT: "TESTED IT WITH REBOOT, DIDN'T DO ANYTHING GOOD OR BAD ITSELF") BOOT, FSCK ERROR MESSAGE (EXIT 1, ERRORS RESOLVED), BOOT CONTINUING...
