Couple of things come to my mind to test: Did you try the file system check from a PC running Linux, either installed or Live-CD? The version of fsck built into backupmenu and also Maemo are ancient, you will get better results from a PC. Did you try to move the file, thereby not erasing the file completely but testing the read/write abilities of the rootfs. You could also check the location of the real file Code: ls -al /var/lib/dpkg/info/mafw-tracker-source.postinst Good luck!
ls -al /var/lib/dpkg/info/mafw-tracker-source.postinst
