Package list loading error

Could somebody tell me what this error is about and how I should solve it?

Cheers in advance.

These commands should clear the lists and redownload them. Bevery careful with the command, as a typo and extra space could erase important system files.

Code:

---

sudo rm -vf /var/lib/apt/lists/* && sudo apt-get clean  && sudo apt-get update

---

These commands should clear the lists and redownload them:

Code:

---

sudo rm -vf /var/lib/apt/lists/* && sudo apt-get clean  && sudo apt-get update

If it doesn't solve things, run this variation to remove the contents of /var/lib/apt/lists/partial:

Code:

---

sudo rm -vf /var/lib/apt/lists/partial/* && sudo apt-get clean  && sudo apt-get update

The first one solved it. Thanks a lot.
