when i try to install i have these messages:

/home/user # apt-get install nfs-common
Reading package lists... Done
Building dependency tree
Reading state information... Done
nfs-common is already the newest version.
You might want to run `apt-get -f install' to correct these:
The following packages have unmet dependencies:
nfs-common: Depends: portmap but it is not going to be installed or
rpcbind but it is not installable
Depends: adduser but it is not going to be installed
Depends: ucf but it is not going to be installed
Depends: initscripts (>= 2.86.ds1-38.1)
Depends: libc6 (>= 2.7-1) but 2.5.1-1eglibc20+0m5 is to be installed
Depends: libevent1 (>= 1.3e) but it is not going to be installed
Depends: libgcc1 (>= 1:4.3) but 1:4.2.1-4maemo9+0m5 is to be installed
Depends: libgssglue1 but it is not installable
Depends: libkrb53 (>= 1.6.dfsg.2) but it is not installable
Depends: libnfsidmap2 but it is not installable
Depends: librpcsecgss3 but it is not installable
Depends: libwrap0 (>= 7.6-4~) but it is not installable
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
