desktop problem debian 10.2

[rufuz]

Hello,

i have installed debian buster 10.2 with LXDE and when I try to open clamtk with the terminal as root i receive this message:

Gtk-WARNING **: cannot open display: at /usr/lib/x86_64-linux-gnu/perl5/5.28/Gtk2.pm line 126.

If i try to open it from the menu or with the terminal but not as root, it works fine.

Before I used stretch 9.4 with LXDE and it worked fine in either way.

I also tryied to open other programs as root with the terminal and i receive other errors.

Is it possible to solve this problem??

Thanks. Bye.

somebody could help me??

For what purpose do you want to open applications as root? This is a very bad practice.

[rufuz]

Thanks for the reply
...usually i don't open programs as root but in this case (antivirus) i do it so it has the permission to scan all files on the the disk.
It works so also with bleachbit..if you want a deep cleaning you open it as root..
Thanks.Bye.

From the F.A.Q. of clamtk:

Code: Select all

ClamTk does not need to be run as root. As a matter of fact, MOST programs on Linux do not need to be run as root. If it is easier for you to update the system signatures this way, that is fine. But as much as you can, please run ClamTk as a regular user.

Sorry!
I didn't know...I thought it was a right thing...besides it worked fine with the previous version!
Anyway, if I want to scan with clamav all the files in the hard disk, i mean all, allso the ones protected or restricted without exceptions, what is the right procedure using the terminal?
Thanks for your help.

Use sudo

"sudo" is a command which allows ordinary users to perform administrative tasks.

This is not the same as running your application with root.

AS ROOT
apt-get install sudo
usermod -a -G sudo <username>

Replace <username> with your username to which you want to grant sudo access.

Now logout & login to get sudo access to those users.

Maybe file a bug report to request a polkit action file be included in its next update. You could probably make one yourself. I don't use this, and a search for "pkexec clamtk" yielded nothing, yet...

I try to translate in english:

thanks Cwf...I contacted the clamtk developers...they told me that it is not a problem of clamtk..they told me I probably drop and I don't have the
permissions as root to access my user desktop.

[Chrisdb]

You should replace <u> with the username you will be using instead of root.

For example:

Code: Select all

usermod -a -G sudo rufuz

[rufuz]

u@host:~$ su -

-bash: usermod: comando non trovato

You don't have the passwd package installed? That's not right.

Code: Select all

apt policy passwd

If it's installed then check root's PATH, you've invoked su(1) correctly so it should include /usr/sbin, which is where the usermod command is located.

Anyway, try the method listed on the Debian wiki page about sudo, which you should have checked before posting.
