I have installed Docker using Docker's official apt repo.
My question is, if I uninstall it using sudo apt-get remove docker docker-engine docker.io containerd runc. Will Docker containers and images will also be deleted?
Or should I run a docker system prune explicitly before uninstall?
I am on a 64bit system, that is what I suspect is creating this problem. I'm trying to install various packages, one of them is libssl-dev.
$ sudo apt-get install libssl-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
libssl-dev : Depends: libssl1.0.0 (= 1.0.1f-1ubuntu2) but 1.0.1f-1ubuntu2.8 is to be installed
Recommends: libssl-doc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
I tried doing sudo apt-get -f install which is suggested in similar question on the site. But this is what I get:
$ sudo apt-get -f install
Reading package lists... Done

Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I researched more on the site and someone suggested to installed the missing packages manually. So I did the same:
$ sudo apt-get install libssl1.0.0 Reading package lists... Done
Building dependency tree
Reading state information... Done
libssl1.0.0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded
Here you can see, the package is already installed.
So my guess here is my system is trying to install 64bit version of libssl-dev but can't find 64bit version of libssl1.0.0. If manually installing, my system is showing that I have libssl1.0.0 which is suspect is 32bit version.
I have many more packages to install which are infected with this very bug.
Here are the output requested by @nephente

I'm using Hindi (Bolnagri) layout to type in Hindi. I'm typing in Hindi for first time.
My problem is, I want to type स्वाद. How do I type that half स?
How to type औ with this layout?
How to type र्श as in आदर्श?
I want to keep gnome-terminal application on top of all the applications, even when it is unfocused. How can I do so?
I normally connect to internet through my mobile phone's SIM card. Its a GSM network.
To connect to internet in GUI manner I go to notification bar, click on network icon, and click on connections name. After connecting the network icon changes to indicate that I have connected to internet.
Can I do it in command line way?
I have vim.desktop file in ~/.local/share/applications/ directory with these lines:
[Desktop Entry]
Name=Vim Text Editor
Comment=Edit text files
TryExec=vim
Exec=vim
Terminal=true
Type=Application
Icon=terminal
Categories=Utility;TextEditor;
StartupNotify=true
MimeType=text/plain;
This .desktop file works fine at this point (i.e. I can search in Unity dashboard it and click it to open vim)
But I wanted more from this desktop file. I wanted to start it in insert mode, so I changed some parts of it, like:
TryExec=vim -c 'startinsert'
Exec=vim -c 'startinsert'
But as soon as I save this file I am not able to search it.
Connecting to internet is only the time when I really need to use my mouse.
I give priority to my keyboard. I only use mouse when I'm tired of using keyboard or in the condition I listed above.
Actually I can't focus on the status bar. What's the keyboard shortcut to focus there?
(By status bar, I mean the panel where time, network status etc. are shown.)
I've got Wikipedia's offline database in .xml.bz2 format. There is also a software WikiTaxi to browse through it. But the problem is WikiTaxi is a Windows only software.
Is there any similar software that works on Ubuntu/Linux.
Please don't suggest me about Wine.
I have desktop edition of Ubuntu.
I like the Terminal so that that I prefer to shutdown my computer with the shutdown command.
However when I type shutdown now it prompts me to enter my password.Is there any way I can shutdown my computer using this command without entering my password?
Most of the time when I do a cd command I also do a ls to see what other files or folder are in that directory. So I want to execute ls everytime I change the directory. I know I can do cd foo && ls but is it really necessary to do && ls everytime?
I mean, whenever I start and save files using gVim, have it know to save the files into my home directory.
This is annoying because each time I save any file using any program then I save it on Desktop first, and then categorize and move it to their specific folders.
While looking in my home directory, I can't see any hidden files named .vimrc or .gvimrc, instead I am seeing a .viminfo file. Which doesn't seem to have any preference information.
Suppose you are researching on a topic and have found something with a tabular form, now you would like to save that in your spreadsheet application to see that when offline, so you fired up OpenOffice Calc or MS Excel and pasted that table.
Now I don't know about MS Excel, but when I pasted in LibreOffice Calc then I seen something like as shown in the screenshot.
As you can see the width of column A B and C can be resized because they are only 3 in numbers, but its hard to edit the height of 1, 2, 3, 4 etc.
Any other way to resize the heights of 1, 2, 3, 4 than doing manually?
For example <header> and <footer> are new HTML5 elements, but as it seems in the screen shot below both the elements are marked as red which probably means Geany is telling :
Warining : Unknown elements
How can I make this normal? What files do I need to edit?
I found that when I revert back to default (white background, as shown in Morlunk's answer) theme then no error occurs. Any way to make this happen in my theme? Because I don't want to leave dark theme
While you are playing any song or other media file on VLC and open another such file, then another instance of VLC opens. (You aren't going to hear and understand anything until you are a robot)
I what to add a "Add to VLC Playlist" to the right click menu of Nautilus as similar in Windows.
I am about to uninstall Ubuntu entirely and reinstall a fresh copy. Before I do that I want to make a list of software/package that I have installed so far. Any way to list out?
The answer by Rinzwind shows how to get the list of all the packages from the time when Ubuntu came and directly installs the packages if they are not present but I want to get the list only; not want to install.
Actually I have a wireless 3G modem that works well on Windows based operating system, its interface software were made Windows centric. It can still connect to internet on Ubuntu or other linux based operating system but it won't show the data counter (the interface which shows how much data has been transferred, at what speed).
If I continue to surf internet in Linux then I won't have any idea how much data has been used and it would become heavy on my pocket. So I just want a software that let me know how much data has been transferred, if there is a limiter; that warns or disconnects me when I reach predefined MBs then its better. Please let me know if there is any software or script or something like that already there.
