I am a newbie running Ubuntu Linux. When I run a scan, I get so many error messages – hundreds of screens at 16 lines each – that the scan seems worthless. The messages fall into three categories: (1) permission denied, (2) operation not permitted and (3) no such device. A few say input-output error. I see others are having similar problems. Is this something common with Linux, and what can I do about it?
You need to run Avast as root to avoid most of those errors, I don’t know if that has anything to do with the “no such device” error
To do that you can do ether one of the two in the command line:
at the command line type the following
su
avast options
(you may want to update avast so before you run avast you should run avast-update)
sudo avast options
(Same as before you may want to run sudo avast-update before you run avast)
Replace options with the arguments and options you want, to see a list of options run avast -h (or avast --help I don’t remember)
I don’t know what you need to do in order to get avast to run with root permissions in Ubuntu, I’m hoping one of the *buntu users here will step in and give you this part.
