I always used the solutions here, Route complete TLD (*.dev for example) to 127.0.0.1 in my previous Ubuntu setups. But today after upgrading to 17 I am not able to make this work no matter what I try.

I installed all the released updates and bug-fixes. But can't make this work. Have you hit the same problem? I didn't do a single config yet, it's brand new install of Ubuntu.

• by default dnsmasq was not installed which I installed it and the status of the service is running
• I tried putting the config on these files /etc/dnsmasq.conf and also tried /etc/NetworkManager/dnsmasq.d/dev-tld but none worked
• I did try these commands in both files address=/dev/127.0.0.1 , address=/.dev/127.0.0.1

I need to run a script which will run many similar commands inside another terminal window (which has a app launched and ready to receive commands).

And the command should be sent to the open terminal that has the app but inside the loop, a new terminal window opens up every time, instead of the commands to be sent to the app in the first terminal.

So far I'm here:

#!/bin/bash

echo "Let's see what we can do";

gnome-terminal -e "./launch.sh"; 
sleep 3s;    
#launched the app which needs to recieve the commands

number=0
while [ "$number" -lt 2 ]
do
        number=`expr $number + 1 `;
        gnome-terminal -e "sample_command -i" "$number";
done

echo "finished";

To download a specified file I need to pass a custom header to the server along with the request but I don't know how to do that using uGet, Is there any way to achieve this?

Note: uget is a graphical download manager that uses gtk2 and libcurl (a curl component).

I was working on a folder with write permissions on terminal when I tried to clean the current directory and start over using

sudo rm -r ./*

But it took some time to finish which made me wonder and that was when I saw that I'm not on the folder I was expecting and I'm actually on the root path, so I just hurriedly aborted using Ctrl+C.

• Ubuntu is working now, So I'm assuming no real harm was done, right?
• How can I know what was deleted meanwhile?
• Is there a way to fix Ubuntu to compensate for what was lost?
• Is there a way of somehow keeping this from happening again? say an extra prompt whenever I try to remove more than 100 files?

I like to know how exactly suspending proceeds in Ubuntu,

1. Is any hardware completely cut from power or their process is just minimized?
2. Other than the screen which parts are put on hold or their power is cut off?
3. If there is any power consumption when suspended, how can I know how much it is and how long I can expect my laptop to be able to be revived before battery is drained?
4. What happens exactly for hard disk and is it safe to carry around the laptop without damaging the hard disk when suspended?

well there are many packages and applications installed by default in Ubuntu, which some relate to old choices made by Canonical like using Unity and stuff like that. But I'm wondering about the decision when they select an specific software over other similar ones to be installed by default on the OS, for example transmission.

• So is there any explanation by Canonical over these kinds of decisions and selections?
• Are these decisions more about system stability and performance rather than popularity?

Well I'm on Ubuntu 16.04, but I guess it applies to other versions too, the problem is that my print screen button is just on top of the Backspace button, and sometimes when I want to clear a word, I hit print screen by mistake which is simply because I work with many keyboards and not all of them have keys in a similar place.

The problem is that by pressing and holding print screen button just for a couple of seconds, Ubuntu starts taking tens of pictures continuously and filling the RAM, which I believe leads to halt in the system and wastes some time to recover from it.

1. I need print screen, don't want to disable it
2. Don't want to change it to another key so that I have to explain about why print screen is not working
3. Can we just make it take a single picture instead of thousands?
4. Can we disable the functionality partially and instead just use the combo version Ctrl + PrtScr?

P.S: It happened once when I was writing this :(

well, just after upgrading my Ubuntu and therefore moving to php7, I seem not to be able to install imagick extension for php using the same old command

sudo apt-get install php5-imagick

I get this error (tried php7-imagick too)

 Package php5-imagick is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'php5-imagick' has no installation candidate

what should I do?

I upgraded my Ubuntu today to 16.04 LTS, everything went fine. But somehow Ubuntu software is not working. by not working I mean:

• The windows opens and I see the Transmission app as featured
• I go to other Tabs and nothing is shown
• I search for an app and it just keeps spinning without showing any error msg or any result
• I've checked and I have a working internet connection
• I don't know how to debug or reinstall it

I'm new in Linux, My Ubuntu has started crashing for some days randomly and closing everything, going back to login screen!!

• Is this the same as when windows hangs and you kill a program? (but Ubuntu killing all of them)
• Mainly how do you trace errors and view crash reports of Ubuntu itself?
• How can I get a log of what went wrong and find the root?
• Is there a troubleshooting solution like windows?
• Is there any popular process or set of instructions to follow in such times?
