AVG Free 8 Invalid Update Control CTF File

AVG Free 8 could not update due to "Invalid Update Control CTF File" error messages. I don't know what caused such problem (and I don't care :) ).

Here is my way to solve this problem on Windows Vista.
1. type "cmd" in start search (which is similar to Run on Windows XP)



2. right click on the cmd.exe



3. choose "run as administrator"



4. type "cd c:\ProgramData\avg8\update\download"

5. type "del *.ctf " to delete all *.ctf files

6. update from AVG8 again.

Install software packages on ubuntu

sudo apt-get install software-package-to-be-installed is a good command to install extra packages on ubuntu.

for example, i would like to install Anjuta IDE
type:

sudo apt-get install anjuta

after that I'd like to install minicom too
again, type:

sudo apt-get install minicom
