how can install all packages without internet in ubuntu 16.04 I am trying to install a software where there is no internet in system.So i need to install all packages which available in Ubuntu 16.04.How can do that?
How can I install software or packages without Internet (offline)? I have a friend who has got a computer that is not connected to the Internet. Is there any way to install software offline easily?

Controversy over verb choice in "neither you nor I {is/am/are} in control" Recursive search in nautilus 3.6 completely breaks my keyboard navigation. I often navigate network volumes, and typing to get directly to a folder and clicking enter was very quick. Now typing removes everything in the view and imposes a 30 second delay which is completely useless.  If it showed whats in the current directory immediately, and then searched it would be fine, but as it is now I just want to turn it off. I couldn't find anything in dconf-settings. Anyone know how to disable it? Fatal error: Class 'SelectQuery' not found in includes/database/database.inc on line 813 Fatal error: Class 'SelectQuery' not found in /home/content/71/11241671/html/drupal/includes/database/database.inc on line 813   We built a site in a subfolder called /drupal while building the site, and then moved the files to the root directory when we were finished but it gave the above error on a WSOD.  I have tried:    flushing the cache before moving  tried the registry rebuild truncating and replacing the registry and registry_file tables with a fresh install copy, and rebuilding the registry again rewrite base in htaccess setting a new base url in settings.php   But nothing has worked.  The second we put the files back into the /drupal folder, it works again. It also looks like the error mentions the file in the /drupal directory, which isnt there anymore.

In the book of first order logic I'm reading they say that if $(\varphi_1,...,\varphi_n)$ is a proof from a set of formulae $\Sigma$, then so is $(\varphi_1,...,\varphi_n,\forall x \varphi_j)$ for all $1\leq j \leq n$. They assume that as an axiom but it doesn't make sense to me. Why if $\varphi$ is true then so is $\forall x \varphi$? For example if $\varphi$ is $x=1$ that wouldn't mean that $\forall x : x=1$ , or would it?  Maybe what I don't understand is: why $(\Sigma \vdash \varphi \implies \Sigma \vdash \forall x \varphi)$ is true but $(\varphi \implies \forall x \varphi)$ is not true?

Let $G$ be a Lie group with Lie algebra $\mathfrak{g}$ and let $\exp :\mathfrak{g}\rightarrow G$ be the exponential map.  In his blog,  that if a Lie group is not simply-connected, then $\exp$ will not be injective.  Conversely, is it true that if a Lie group is simply-connected, then $\exp$ is injective?  If not, what is a counter-example? Preface:  An axis plotted with  is usually using the current math font for its ticklabels. But if they are overwritten by e.g. xticklabels={-8,-6,...,8} then the current text font is used. Also an axis label ylabel={Y} would be in text font unless put explicitly in math mode ylabel={$Y$}. However it would be nice, if  one hadn't to do so.   Question:  I'm aiming to ensure that pgfplots always uses the current math font. But please assume that the classic font commands like \rmfamily are screwed up by the corporate design I'm supposed to use, e.g. assume: \renewcommand{\rmdefault}{\sfdefault}  It works if I explicitly define a font  \newcommand{\pgfmathfont}{\fontfamily{pxfonts}\selectfont}   and pass it to pgfplots together with assume math mode=true:  \begin{axis}[ font = \pgfmathfont,  tick label style={/pgf/number format/assume math mode=true} ]   But it requires that I insert the name of the current math font. How can I do that automatically? How to get the currently used math font to insert it into the macro?    MWE  \documentclass{beamer}  \usetheme{Warsaw} \usefonttheme{professionalfonts} \usepackage{pxfonts} \usepackage{pgfplots}  % screwed up by Corporate Design \renewcommand{\rmdefault}{\sfdefault}  % I'd like this line to be generic! \newcommand{\pgfmathfont}{\fontfamily{pxfonts}\selectfont} %           put current math font here   X  \begin{document}  \begin{frame}  This is a basic equation:    \[ x + y = 42\]  \begin{tikzpicture}     \begin{axis}[ %   font = \rmfamily, % makes no sense here     font = \pgfmathfont,      xlabel={$x$-label: I want to be in math font!},     ylabel={Y},     xtick={-4,-3,...,4},     xticklabels={-8,-6,...,8}, %   xticklabels={$-8$,$-6$,...,$8$}, % does not work     tick label style={/pgf/number format/assume math mode=true}     ]      \addplot {x^2};      \end{axis} \end{tikzpicture}  \end{frame}  \end{document}     Everything related to  is no option at all!  Thank you! What is the difference between a class and a set? I know what a set is. I have no idea what a class is.   As best as I can make out, every set is also a class, but a class can be "larger" than any set (a so-called "proper class").  This obviously makes no sense whatsoever, since sets are of unlimited size. It's not like you get up to 25 elements and go "oh, hey, sets are limited to a maximum of 20 elements, so we'll have to call this 25-element thing something else".  Does anybody know what the actual difference between a set and a class is?  Several people have pointed out that you can write paradoxes which involve sets. I get that. But where do classes come into the picture? Reading shapefile using C#? Is it acceptable to vote to close a question without leaving a comment? Although  is obviously an exceptionally poor question, it still amazes me that 5 people can vote to close and yet not one of them leave a comment to help explain how the poster can improve their question.  I see loads of similar examples where questions from new users are closed and heavily voted down without anyone taking any effort to explain why - not a pleasant experience for new users.  Is there anything that can be done to encourage users to leave comments when voting to close? Why does cycle rendering only use one core from an AMD GPU? Calculate intersection of a line with a plane I was reading something about: “Intersection of a line with a plane”. But I don’t fully understand how to calculate it on their way.  The goal is to calculate where the plane and the line will “cross”. These items are given:   The eye is in position: O(0,0,-10)   A point of a 3D-object is P(10,20,30) The screen has the equation z=0   I have a questions about how they calculate this:    This part is clear. That is the location form the eye (vector representation).   They specify the location of the plane, there is nothing strange here (vector representation).   Now they calculate what part of the line will cross, how did they calculate this? How did they know a = 1/4? And b = 10/4?  This is everything that was given. Why is my network interface named enp0s25 instead of eth0? A lot of my scripts stopped working after installing Ubuntu 15.10 and I have trouble remembering this new name as I was used to ethx and wlanx for years. Is there a reason for this change? Do I have to get used to this or can I just rename it and go back to good old eth0?  $ ifconfig  enp0s25   Link encap:Ethernet  HWaddr 77:5a:5e:a6:86:d5         inet addr:192.168.31.239  Bcast:192.168.31.255  Mask:255.255.255.0       inet6 addr: fe80::725a:b6ff:fea6:86d7/64 Scope:Link       UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1       RX packets:4833 errors:1332 dropped:0 overruns:0 frame:666       TX packets:5589 errors:0 dropped:0 overruns:0 carrier:0       collisions:0 txqueuelen:1000        RX bytes:3266446 (3.2 MB)  TX bytes:1046654 (1.0 MB)       Interrupt:20 Memory:d3500000-d3520000 Lines appear on the texture in render I am trying to learn Blender.
