Yes and no

apt-get install refuses to run because of dependencies not satisfied :

Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run `apt-get -f install' to correct these.
The following packages have unmet dependencies:
  libc6-i686: PreDepends: libc6 (= 2.6.1-1+b1) but 2.6.1-3 is installed
E: Unmet dependencies. Try using -f.


and that is the result of apt-get install -f :

Reading package lists... Done
Building dependency tree
Reading state information... Done
Correcting dependencies... Done
The following extra packages will be installed:
  libc6-i686
The following packages will be upgraded:
  libc6-i686
1 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
2 not fully installed or removed.
Need to get 0B/1202kB of archives.
After unpacking 0B of additional disk space will be used.
Do you want to continue [Y/n]?
