I need to be able to setup a ssh key system without interaction. I don't care if packages need to be installed or passwords in clear text.
How can I make a system that sets up a ssh key system, allowing machine A to ssh into the machine B and vice versa using ssh keys, without interaction?
I can find no official information for this:
I love snaps and really want to use Ubuntu Snappy Core on my PC. But I cannot find how to do this! It seems to only be supported using KVM, embedded devices or Rasperry Pi.
So how can I install Ubuntu Snappy Core on a traditional PC?
I want to create a video (bar.xxx) that is lossless from a video (foo.xxx) using ffmpeg. Could you please show me the parameters for such a video. The video must be playable on VLC and/or Totem. The wrapper format must be either mp4, avi or mov.
What is the Ubuntu 16.03, 16.05, 15.11, etc? I was typing Ubuntu 16.04 and accidentally typed 16.03. I saw things like Ubuntu 16.03, 16.05, 16.01 on launchpad. They were milestones relating to the next Ubuntu release. What is this about?
I have the following file foo.txt:
1
AbcdJ
8192
Pak78
8291
I would like a bash script that extracts all the lines containing only integers (e.g. 1, 8192 but not AbcdJ or Pak78) and outputs it to bar.txt.
Snap packages each have their own copy of dependencies. This means there are lots of packages in each snap, which would equate to large package sizes. Wouldn't this mean that snaps would be so much bigger than traditional debs? How can I make them smaller? I have limited space.

How do I edit the binary data of a file in a gedit like editor? Eg:
00001010101010010101
And how do I edit the hexadecimal data of a file in a gedit like editor? eg:
91021AF9B
I do not want one editor with both. I want two different editors.
I have looked a GHex and it is not what I want.
How do I install multiple versions of Chrome? I would like to say, I want Chrome, not Chromium. Or is there a extension (like Firefox)?
I have had this issue for a few weeks. I use Ubuntu 14.04. I love GNOME and decided to upgrade to 3.12.
Then I later decided to downgrade to 3.10, using ppa-purge. I ran sudo apt-get dist-upgrade and rebooted. Now I cannot find GNOME in my desktop selection menu.
How can I fix this?
I have installed Ubuntu 14.04 on a laptop and installed apache 2 (version 2.4.7) and PHP 5.
I cannot find httpd.conf. I need to change it because when I try to open a .php page I see a download box.
How should I proceed?
