Can't open update manger,package manager or software center.   The following code appears when I attempt to launch the above:     Could not initialize the package information  An unresolvable problem occurred while initializing the package information.  Please report this bug against the 'update-manager' package and include the following error message:  'E:Type '“deb' is not known on line 58 in source list /etc/apt/sources.list, E:The list of sources could not be read.'    Tried to 'gedit' it, apparently it doesn't handle 'E' Files?  Thank you in advance for your help.
Every once in a while I see users having issues to update due to errors like this:  E:Type 'ain' is not known on line 1 in source list /etc/apt/sources.list.d/some-ppa.list'   with varying types/line numbers/source list files (often after removing a PPA).  How can such an error be fixed?
How to set an alias on a per-directory basis? Suppose you have an alias go, but want it to do different things in different directories?  In one directory it should run cmd1, but in another directory it should run cmd2  By the way, I have an aliases for switching to the above directories already, so is it possible to append the go alias assignment to the foo alias?  alias "foo=cd /path/to/foo"   Working in bash(?) on OSX. When and what cause Voldemort to look the way he does, vs how we've seen him as a teen? As the title says, when and what made Voldemort look the way he does (pale, snake-like etc) as opposed to how we've seen him in his earlier years as Tom Riddle? Is it just a side effect of his unnatural resurrection? Before he died attacking Harry as a baby did he look like a normal guy? software updater failed to download repository information When I run software updater it says that it failed to download repository information and to check Internet connectivity.  I have Internet connectivity.  How do I fix this?  editing to add content of sources,list:  sorry I can't figure out how to paste in the content of sources.list without making a huge mess.  Some of it previews as really large bold print.  I tried to follow the block quoting and code rules but it is a huge mess anyway. The orbit of satellites around Earth eventually decays, or so I read. This is typically caused either by atmospheric drag, or by tides. I would assume most satellites have a limited service life in orbit. Hence the question - What is the typical orbital life of a satellite? How long before it's successor must be launched into orbit ?  EDIT: For instance, a weather satellite Setting Blend Width on Mosaic Dataset using ArcMap I installed Ubuntu (twice actually) onto the same drive. I wanted to 'try again' since one of them didn't install correctly and the other installed differently, but it worked.   I was getting frustrated with the GRUB menu because it was really sloppy (There were two Windows options - one with the Windows bootloader to go into Ubuntu, and two different versions of Ubuntu from the first install for some reason and memtest, etc.).  In my attempts at getting rid Ubuntu to do a fresh installation, I went ahead and deleted the partitions that weren't swap or main via Windows 7. As I said, I am a noob.  Now, even though I though I completely got rid of Ubuntu, including the GRUB menu, when I boot my PC I am brought directly to GRUB Rescue. And from what I've found from other forums, GRUB rescue isn't even completely functional for me (it doesn't recognize any commands that it should support besides ls. It also returns unknown filesystem for any partition I try to view or boot.)  Is there any way that I can boot straight into Windows? I fear I may have gone about deleting those partitions in the wrong way. If so, what are my options? Suppose a vibrating fork exerts force to the air particles to compress which leads to the increase of internal energy (heat).This heat or energy given by the fork is given to the next layer of air and in this way, this energy makes sound. But if it was so, it will be isothermal. And Laplace told it was adiabatic. How can it be? I am confused. The heat energy infact is the energy given by the fork. If it is adiabatic, how can the air pass this energy ? How should sockpuppets be handled on Stack Exchange? A high-reputation, highly-active user has already been dinged once for a sockpuppet, and I just dinged him again. He probably has another sockpuppet as well.   What are the guidelines for handling users who game the system in this fashion? Specifically,   How can I be sure I'm looking at a sockpuppet? When should sockpuppets be considered a problem? How should moderators handle problematic sockpuppets once they've been identified? I was suspended for sockpuppetting and feel this is unfair I'm looking for a book that starts with the premise that (once the population size had exceeded a certain number) the future development of mankind (revolutions and wars in so and so many years, colonization of other planets in so and so many years, and so on) could be predicted completely by applied statistics. (IIRC, they used slide rules for those exact predictions, but that is certainly owed to the time the story was written). Next, the predictability was used to take a few tiny measures that would change mankind's fate in a favourable way. After a long time, the predictive system fails(?) because a mutation occurs in some person(s).  And now is the part where I'm not sure if it belongs to this or another story: The mutation results in the ability to "beam" by thinking of a place where one has been before... What is a word/idiom for 'unable to decide'? Let's say I have an important decision to make and I can't decide between two competing things (like break up with a girl or not break up with her). What would be a word/idiom to express that? When does Hamiltonian equals to energy of the system? Contribute to bounty? Why does the weighing balance restore when tilted and released For example, this regex  (.*)&lt;FooBar&gt;   will match:  abcde&lt;FooBar&gt;   But how do I get it to match across multiple lines?  abcde fghij&lt;FooBar&gt; Excel How to make Text Qualifier editable or add a new entry in the existing list? What kind of things can you take from a hotel? Hotels normally provide a big amount of sets (well, depending on the quality, but however, many!) that can help you feel more comfortable there.  So for example you can get towels, slippers, candies, pens, shampoos, shaving kits, sponges, ...  The same in the self-service breakfast: pastries, bread, ...  They are meant to be used during your stay. However, they can be provided in such an amount that there are some extra by the time you leave... and make you feel like taking some back home.  My general rule is to take those things that I used but didn't finish. However, sometimes I may be tempted to take the brand new stuff lying there before I close the door for the last time.  So the question that pops is: what kind of things is it correct to take from hotels and what is it not recommended? Else, what items may differ from country to country? What is "the ground"? I want to know how to get the X and Y position of HTML elements such as img and div in JavaScript relative to the browser window. Is there actually a 0 probability of finding an electron in an orbital node? Why does a RegExp with global flag give wrong results?
