Mageia forum

Hi,

For the past couple of weeks, I have been facing the issue of launching software manager in Mageia. It works most of the times, but does not work few times.

When I try to launch it from the command line, I am seeing the below error after entering the root password.

Code: Select all

[bneelka@localhost ~]$ gksu rpmdrake
Unable to get Terminal Size. The TIOCGWINSZ ioctl didn't work. The COLUMNS and LINES environment variables didn't work. The resize program didn't work. The stty program didn't work. at /usr/lib/perl5/vendor_perl/5.20.1/x86_64-linux-thread-multi/Term/ReadKey.pm line 451.
No protocol specified
[bneelka@localhost ~]$


Can some one help? I am not sure whether reinstalling perl will help.

Thanks,
Balaji.

Why do you run it via gksu ?

At the very least please provide the output of the following commands, run as your regular user in a terminal:

Code: Select all

loginctl show-session $XDG_SESSION_ID
ps -ef|grep -v grep|grep -iE "polkit|policykit"
pkexec whoami     # you need to enter your root password when asked by the authentication dialog
echo $DISPLAY

and as root from:

Code: Select all

systemctl status polkit.service -a

Whenever we launch the graphical package manager, it asks for root password, right? That is the reason I launched rpmdrake via gksu.

Output of the commands are below.

Code: Select all

[bneelka@localhost ~]$ loginctl show-session $XDG_SESSION_ID

Perhaps caused by the problem with Term::ReadKey discussed here:

Nope, only a cosmetic issue, but not the cause. One line afterwards in the OP is the problem:

Code: Select all

No protocol specified

this happens when the underlying code cannot figure out if it should run with the X frontend or with the ncurses one, usually this happens when $DISPLAY is not set properly or something like that.

Well, why don't you ask how to configure it to ask for the user password or for no password (for a single-user workstation e.g.) ?
For that, please see http://doc.mageia.org/mcc/5/en/content/draksec.html

Thanks for the clarification about the bug.

Is there a fix for the "No Protocol Specified" error? What makes rpmdrake to act like this?

Thanks,
Balaji.

Hi doktor5000,

Today I am having problems launching the update manager and I tried the commands that you provided last time.

The command "systemctl status polkit.service -a" is outputting different result than last time. The output of the command is below.

Probably due to gksu, and the fix is to run like it's intended to be run.

For the polkit output, the systemctl status polkit.service -a is mostly irrelevant if it's running, the other outputs are important.

This is happening irrespective of whether I use gksu or not. rpmdrake is spitting this error even when I launch the "Install & Remove Software" from the menu.

Thanks,
Balaji.

Based on some google search and little bit of troubleshooting, I was able to solve this issue by adding the below two lines in ~/.bashrc file.

xhost +local:root
export DISPLAY=:0.0

Thanks,
Balaji.
