After battling a black screen and a boot loop I was able to boot my PC successfully. After using it a couple days, I understood that it doesn't connect to the internet anymore. And by that I mean it could ping 8.8.8.8 but none of the apps including the browser could connect to anything. I could not update any of the apps either as the update module gave me an error for unmet dependencies.  I tried a couple fixes without success.   I decided to say f it and install it fresh after backing up my files. Now that I'm trying to boot my PC and it's not going past the logo screen. What is the fix?

I did a fresh complete install of Ubuntu 18.04 on my ASUS M32CD desktop.   Everything during install went fine. At the end it said it was complete complete, and would reboot. Popped the disc out. Rebooted itself back into bios so I changed it back from CD boot as primary to HD.  When it booted up for Ubuntu screen and then everything went black and can’t do anything now! Ugh. Help

I disabled all services and startup applications and now the computer won't let me log in. It will get me to the initial startup screen, but it won't connect to the Internet. Then when I click or press a key to log in, the password box never appears.   How to go back to normal boot? Shift+Restart or F8 to get into safe mode doesn't work. Restoring to a system restore point resulted in an error. Even Resetting Windows didn't work.

After I installed Ubuntu , I cannot update any software with the error message "failed to download package files". After having googled, I have tried:   sudo apt-get update sudo apt-get upgrade changed to another sources   But I still got the same error message. And there is no problem with internet connection as i can connect to internet using Firefox in Ubuntu.  Any ideas?

A little background - I have a Lenovo G50 which was running Windows&nbsp;8.1 up until a few months back. Then came along the free upgrade to Windows&nbsp;10. Microsoft updated the laptop OS to Windows&nbsp;10, and all was fine in the first run.  But, as soon as I shut the laptop down, and powered it back up the next time, it just would not connect to the same Wi-Fi hotspot. This situation continues until today. Every time it's the same message - "Can't connect to this network".   The only way I got around this until now, was to manually reboot the Wi-Fi router, and as soon as the router would come back up, Windows&nbsp;10 would instantly get connected. I have no idea how/why this worked, but while it did work fine up until sometime back, I can't keep doing this anymore. I share my apartment with a few other guys, and having to disrupt their Internet connectivity every single time I turn on my laptop - is not just a minor convenience anymore (not that they haven't voiced their concerns over this, anyway).  I looked at this  question, and tried to check my "advanced adapter options", but it all seemed correct (attaching pictures below).         All other devices [MacBook Air, MacBook Pro, iPhones, iPads, Windows 8.1 (running on a Dell and an HP)] connected to the same Wi-Fi hotspot in this apartment, work just fine.

I'm not really sure how, but after I woke up today, my phone was just displaying the loading spinner and doesn't start up anymore. It's weird because my phone turned off last night and suspecting that it was probably out of charge, I thought charging it overnight would fix the problem.   So, my iPhone is currently stuck on the iTunes/Apple Logo loop. When I put it into DFU/Recovery Mode and connect it to iTunes, it isn't able to restore it. It keeps throwing "Network Connection Problems" -- it downloads iOS 10 for a bit and suddenly stops downloading, throwing the error. I've also tried downloading a custom .ipsw from  but it seems that the file is corrupted whenever iTunes tries to unpack it.   Any thoughts on how I could go about fixing this?   Note - I don't have a jailbroken iPhone.

Computer was humming away happily.  It had downloaded a kernel update eariler in the week and been asking for a reboot since.  This morning I relented.  When the computer powered back up it made a loud repeated clicking noise which I tracked down to my hard drive by opening the cover.  Since then I can't boot the computer - it keeps failing out to netboot (which goes nowhere).  Based on a quick google I think the disk is history.  Does anyone know of a way to recover the disk?  I realise I'm probably SOL but it's worth asking.   Edit  Thanks for the answers.  All very interesting and informative.  Nothing on the drive is worth the cost of a professional recovery service and my backups cover the important bits anyway.  I was just hopeful that I might be able to avoid the nuissance of a rebuild on a new disk.

The latest version of Ubuntu server (18.04) seems to demand network configuration and refuse to boot without it. I have no desire to connect the server in question to the internet for anything, and have installed previous versions of Ubuntu server without network no questions asked.  Is a network connection an absolute requirement for the latest version of Ubuntu server? Or is there something I'm missing?  The installation cannot proceed past the network configuration page unless an ethernet connection is active, by my current estimates. I have no ethernet network within range of the machine so can't test it on an internet-less network. I only have WiFi within immediate range (which does have internet access) but it won't recognise the device and it should be simpler to get the installation to happen without any updates than to go to the effort of finding the drivers to support the WiFi adapter.  Note that this is NOT a duplicate of  since the new installer seems to be the real problem here.

I have a small issue with my Ubuntu (I think After an upgarde). When I try to login (Login Screen), I get disconnected and get back to the screen (again &amp; again).  I tried:   Trying to login with others Desktop environements. Booting from old kernel. log in via command line [apt-get update &amp;&amp; apt-get upgrade]. removing ~/.gconf directory. sudo apt-get install --reinstall ubuntu-desktop and sudo apt-get install unity   None of these solutions worked.

first question here. I was using wifi normally on my phone. Then I turned it off and after some time turned it back again. Since then I can not access the internet. It's showing Connected(no internet access).  I tried to set the IP static. It did not work for DNS 192.168.200.1. No matter what IP I set with this DNS it does not work. Then used the 8.8.8.8 as DNS, now it's connected. But it is really slow, and the connection does not seem stable. Every time I have to reload google.com several times just to get the page.  The problem is specific to this device only. Other devices connected to the same network are perfect.  Can someone suggest me what should I do? Is this a router issue? Or is this my device problem?  I'm new in this area. So my knowledge is not so deep and you might have to explain things a bit more in detail for me to grasp the concept.

I have a computer which is working fine after a windows re-install.  However, I did not install any drivers at all, they seem to have been installed via Windows Update.  Back then, I remember I had to download the latest drivers from the motherboard manufacturer, video-card manufacturer, etc.  Is this still valid?  Should I download the latest drivers from the manufacturers, or are the drivers available via Windows update enough?  I am running Windows 8.1.

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.

If there's a bad hardware driver that is causing Windows to crash during startup, how can you update the driver?  Do I need to make a boot disk?  I have the driver installation disc that came with it and tried to boot from it; obviously that didn't work.  Is there a way to do this?  I'm not sure if it's indeed a bad hardware driver that's causing the crash, but I'm getting a BSOD with a DRIVER_IRQL_NOT_LESS_OR_EQUAL - among other things I want to try updating the drivers, but I can't get into Windows to do it the normal way.

I bought a new computer, hoping to dual boot Win 8 and Ubuntu 13.04.  I have successfully installed both OS, but in Ubuntu I have no connection to the internet, even though the ethernet cable is plugged in and internet works perfectly in Win 8. Already in the Ubuntu installer, it says that I have no internet connection.  Things that might be of interest:   I have this motherboard: MSI Z87-G45 Gaming () Internet did not work in Win 8 until I installed the networking drivers that came with the motherboard (Killer Ethernet something) I have tried different installation configurations, tried v. 13.04, 12.04 and 12.10, and tried installing on a separate hard drive. (the fact that the installer says "no internet connection" seems to indicate that the problem has nothing to do with the installation though.) I can't even reach my router at 192.168.0.1.  The motherboard has no wireless capabilities.  If I run the terminal command lspci I get the following output (among other things):       03:00.0 Ethernet controller: Qualcomm Atheros Killer E2200 Gigabit Ethernet Controller (rev 13)   I have spent hours and hours googling, trying many different suggested methods and not quite finding someone who seems to be having the same problem.

I disabled all services in services using msconfig and restarted.  Now - my login details no longer work. I have no network access and the forgot my password option doesn't do anything.  I have restarted using shift+restart to try get into safe mode but this just brings me to the same logon page.  Does anybody know what caused this or how I can resolve the issue?
