I try to run sudo apt-get upgrade and I get the following output:  Preparing to unpack .../snapd_2.32.8+18.04_amd64.deb ... Unpacking snapd (2.32.8+18.04) ... Setting up snapd (2.32.8+18.04) ... snapd.snap-repair.service is a disabled or a static unit, not starting it.   This just hangs here, I've tried running it for over an hour now and nothing. It means I can't install anything at all, all other packages seem to work fine.  I have also tried purging snap and then reinstalling it but I just end up back where I was.
I have recently upgraded my OS to Ubuntu 18.04 (fresh install via boot device). However, when trying the command:  sudo apt-get upgrade   It works fine until ~75% when it stops and says:  snapd.snap-repair.service is a disabled or a static unit, not starting it.   I'm not quite sure what this means and if I Crtl-Z to get out of it, any time I try to install anything I get:  E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?   and have to restart my computer to install anything.
How to "freeze" a cloth animation at X frame? How would one freeze a simulated body at frame X and use it as a static mesh?  Following a , I've been able to do a cloth animation to my model, now I'd like to have that made static, without the use of the timeline.   The thing is, I'm modelling something that's not going to be an animation, but a static object (something like a statue/figurine). So I don't need the animation, only the shape at a particular frame that I find convenient. I'd like eventually once this is done, to also modify that deformed grid.   I've tried to follow what was said , but couldn't figure out what chipmasque was saying. I'm quite new to blender (been using it on and off, just enough to forget everything).  I'm using blender 2.63, if it is of any relevance. Would a wormhole be able to move? PHP syntax for dereferencing function result How to compute $\int_0^{\pi/2}\frac{\sin^3 t}{\sin^3 t+\cos^3 t}dt$? Can I skip over releases when upgrading? I am currently using Ubuntu 10.04. I know there is a 10.10 release, but can I upgrade directly to 11.04? Could you walk me through the steps please? Passive voice phrasing of "The bottle contains two liters" What is the proper use of [square brackets] in quotes? How do I get rid of the Start Menu "zombie" icon? Windows 7 has a large icon above the username on the right-hand pane of the Start menu. By default it is a faceless torso in a blue collarless shirt that I call the "zombie icon". (I don't know the icon's real name: . (Although "Molly Clark" has a zinnia icon instead of a zombie icon.)  The zombie icon fades from one pointless icon to another as you move your mouse over "Documents", "Computer", "Devices and Printers" etc. This icon is a waste of space and the fades are distracting.  How do I make it go away? How to make read-only file system writable? At some point, the filesystem on my digital audio player has become read-only. I cannot copy files into it or remove files on it.  Are there some possible reasons for the player's file system to change permissions in this way?  I tried using chmod:  $ sudo chmod a+rw SGTL\ MSCN/  chmod: changing permissions of `SGTL MSCN/': Read-only file system   SGTL MSCN is the mount point of the digital audio player.  What else can I try to make it writeable? Someone found this quiver with surprisingly high values, although I'm unable to find a level 30 rare quiver on     Given that the item's internal level (IIL) determines which affixes are possible, I'd like to know whether the IIL affects the minimum/maximum rolls for an attribute, a graph or table would be great.  For example, let's say items are able to get a pure +intellect affix from IIL 20, what's stopping you from rolling 250 at 20?  Is it a bell curve, which has shallower gradients with a higher IIL of the item?  Is it capped, dependant on IIL?  Do the min/max caps step up at certain IILs,though it's the same attribute? For example, IIL 20-40 is capable of 5-120, IIL 41-60 is capable of 20-320, ..., IIL 63 = 40-400 Windows 10 doesn't shut down properly I have visited tons of websites and watched dozens of Youtube videos, yet I can't find a solution to my problem.  I recently upgraded my laptop to Windows 10, and now it won't shutdown properly.  I have turned off fast startup and sleep mode from power options.  Here is what happens:   Start menu > Power > Shut down It exits windows and apparently turns off (black screen) The power lights are still on and my computer apparently doesn't shutdown. Incompatibility with mathtools and unicode-math in xelatex? I find unexpected behaviour in using mathtools in conjunction with unicode-math, which shows up if the 'range' command is used. Some incompatibilities have been noted before, so perhaps this is related. However, it only showed up for me in Texlive2016; previous versions worked as expected. In the following example I wish to draw calligraphic fonts from a different set than the main maths fonts, and some calligraphic symbols, and a regular italic bold face math, are missing.   \documentclass{article} \usepackage{mathtools}  \usepackage{fontspec} \usepackage{unicode-math} \unimathsetup{math-style=ISO,bold-style=ISO,sans-style=italic} \setmainfont{xits-regular.otf} \setmathfont{xits-math.otf} \setmathfont[range={\mathcal,\mathbfcal}]{latinmodern-math.otf} %\setmathfont[range={}]{xits-math.otf} % Try with and without this line % \begin{document} Test $a+b = \mathcal{C H G}C \mathscr{D}$ $$-\frac{a}{b} \mathcal{O} . $$ \begin{equation}     \mathrm{d} = \mathcal G(\varphi,x,y,z,t) ,  \end{equation} The symbol $\mathcal{G}$ is missing.  The following equation is wrong if I include the line  ``setmathfont[range=\{\}] \{xits-math.otf\}'' \begin{equation}     \mathup{d} = \symbf{u}(\varphi,x,y,z,t) ,  \end{equation} The glyph $\symbf{u}$ is missing. \end{document}   If mmathtools is called after unicode-math the problem does not arise, but this ordering is not recommend by the unicode-math developers.  My specific question is, is this a bug or is it something I am doing wrong? How can I make Firefox open magnet-links in Transmission? I can't find out how to make Firefox open magnet-links in Transmission.   There is no option to make it the standard program for magnet-links in its properties, and as I am not experienced with the filesystem so I can't add it as the standard program in Firefox either. What does it mean to accept an answer? How do I accept an answer, and what are the rules? Can I accept my own self-answer? What are the reputation benefits? Which answer should I accept?

For more information, see "" in the . int fn();  void whatever() {     (void) fn(); }   Is there any reason for casting an unused return value to void, or am I right in thinking it's a complete waste of time?  Follow up:   Well that seems pretty comprehensive.  I suppose it's better than commenting an unused return value since self documenting code is better than comments. Personally, I'll turn these warnings off since it's unnecessary noise.    I'll eat my words if a bug escapes because of it... How can I save application settings in a Windows Forms application? How to assign many variables the same value in a smart way? Why is the $(\frac{1}{2},\frac{1}{2})$ representation of the Lorentz group realized as the vector space of Hermitian $2\times 2$ matrices? Should I have more than one brokerage account? I have my brokerage business with one particular well-known US brokerage house. I find being able to access my retirement accounts and personal investment accounts through the one interface useful.  However, I was talking with a friend of mine and she said she never puts more than about $50k into any particular brokerage account.  Managing three or four such accounts seems like too much overhead for me. I'd prefer to spend my "investment time" reading up on my investments and researching new ones.  One reason to have more than one brokerage account with different houses is the issue of  insurance:     Within limits, SIPC expedites the return of missing customer property by protecting each customer up to $500,000 for securities and cash (including a $250,000 limit for cash only).   What other reasons could I have to use more than one brokerage account? Let $G$ be a finite semi-group with identity such that it has only one idempotent.Is $G$ a group?
