error for apt-get install

[kene]

halo all, i'm still noobie with knoppix, so at the time i tried to update package, there's following error shown up:


#apt-get install libssl0.9.6

Reading Package Lists... Error!
E: Dynamic MMap ran out of room
E: Error occured while processing php5-cli (NewVersion1)
E: Problem with MergeList /var/lib/apt/lists/ftp2.de.debian.org_debian_dists_unstable_main_bina ry-i386_Packages
E: The package lists or status file could not be parsed or opened.


so, what's the meaning of these? i tried also to look my space it's shown like this :

# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda7 7052464 2605304 4088916 39% /
/dev/root.old 2182 341 1841 16% /initrd



or if looked at free memory, i had this :


# free
total used free shared buffers cached
Mem: 515256 328496 186760 0 21796 222900
-/+ buffers/cache: 83800 431456

thanks in advance
