apt-get upgrade
apt-get dist-upgrade

---

- I run the following command to install linux header as follow:

Code:

---

apt-get install linux-headers-3.18.0-kali3-686-pae

---

and it gives me an error as follow:

Code:

---

---

- I run the following command

Code:

---

apt-get install linux-headers-$(uname -r)

---

and it gives me the same error.

then I notice that during the update is looking into i386 packages and not not amd64 packages as follow:

Code:

---

...
Hit http://http.kali.org sana/updates/nonfree i386 Packages
....

---

Then I check my system as follow:

Code:

---

uname -a

---

and it gives me the following:

Code:

---

Linux kalitool 3.18.0-kali3-686-pae #1 SMP Debian 3.18.6-1~kali2 (2015-03-02) i686 GNU/Linux

which indicate that my system is i686 and I am not sure why my update is looking into i368 and so cant find the required linux headers
Please help.
