It is very strange,  I just installed Ubuntu 16 on my computer, and at the end of the installation, the system says that I need to restart my computer. When I do it, I get back to the black screen that asks me if I want to try Ubuntu or if I want to install it. I'm stuck in an infinite loop.  However the first time I did the installation, I was able to do the crypted one, protected by password. Now I can't. Also, sometimes the system says that some files already exists, which certainly come from the first installation, and that it may cause issues.

I created a live usb to boot Kubuntu, which has worked well enough. However, when the installation gets to the point of telling me to restart the computer (and it restarts) the installation window pops up again, and the computer is still signed in as a live user. None of the installation or settings appear to have saved.  Any ideas?

I was running Ubuntu 17.10 on my mac (mid-2010) as a dual-boot with Refind as the boot manager. It was functional albeit non-optimal drivers for wifi and video card.  A day ago, the Software Updater app gave me the option to upgrade and I took it. It completed the install and clean up fully but I was unable to do a final restart due to power issues. Anyway, after the power issues were sorted out, I booted my laptop, only to find that it wouldn't boot into the OS and would get stuck in a loop at a screen which was filled with lines of code that made no sense to me.  So, I rebooted with option key and booted into recovery mode and ran check disk and fix broken packages and then resumed boot. Then it booted into the OS fine. I rebooted again, and then it went back to the screen with lots of lines of code which no sense. I tried the same thing again with the recovery mode again. And this time when it booted I picked the proprietary Nvidia drivers. Now when I boot, there is just a blank screen and I cant boot into recovery mode either because there is an error in EFI screen option.  So I boot into OS X and download the ISO file for 18.04 and make a bootable USB stick and boot into that from the EFI screen. Now, it boots and once past the orangeish blue bionic beaver wallpapers, it gets stuck in a loop at a message called setting locale.  So, at this point, I can neither boot into my HDD Ubuntu install nor into the Live Disk.  My next plan of action is to try and get an ISO of a previous version and try booting form that. I'd like to avoid that if possible and stick to 18.04.  EDIT 1: I flashed Ubuntu 17.10 onto the USB storage, and that boots fine. I'll try 18.04 once again. Also, I'm using Unetbootin for flashing the USB storage.  EDIT 2: This keeps cycling over and over when I live booted from a freshly downloaded copy of Ubuntu 18.04 ISO file flashed in to a USB:    Keep in mind that when I do this on the same USB with the ISO file for 17.10.1, live boots perfectly fine.   EDIT 3: I've given up. I'm doing a clean install of 17.10.

There's been one problem I've had since I installed Ubuntu to run alongside Windows, I assume this would also be the same if it was installed to replace the other operating system as well, the installer prompts you to create a password upon typing in the user account name and if you don't put in a password and just put in the user account name, it ends up saying to create a password. My comparison is in Windows and Mac OS X, you are never forced to create a password.  If you remove the password on your Admin account in System Settings > User Accounts, you won't be able to authenticate whenever you try to install something, because it requests for a password and putting in no password at all isn't going to work, it will just act as if you put in an invalid password. This is what I call "getting locked out of privileges".  I'm finding the "Authenticate" window that comes up whenever you install something or accessing somewhere a nuisance, 'cause it always requests for your password.  So my question is - Why does Ubuntu force users to create a password upon installation?

When I turn my PC on, it asks me if I want to boot Ubuntu 16.04 or Windows 10. When I choose Ubuntu 16.04, it look like it is booting, but then it just show me this screen:  BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash) Enter 'help' for a list of built-in commands  (initramfs)   I was installing Ubuntu by CD. First time, when was installation complete, the system was running without any problems, but when I turned my PC off (there wasn't any problems or messages during the shutdown) and then turned it on and choosed Ubuntu this happend.

I'm at a library, and all of the computers are Windows based.  I'm sshing into my Ubuntu box somewhere else. The terms of service says "You may not make any changes to system files." However, when I ssh into my Ubuntu box, it might "look" like I'm hacking, since I've had a few people (including I presume the library supervisor) look at my computer funny when I opened a website where the text was a monospaced font and the website background was black. Running Command Prompt will certainly be considered to be hacking if looking at a website was.  If I'm sshing into my box it appears as though I'm "hacking" into the computer. I'd like to somehow do it in a web browser with nice happy looking text, so that it actually represents what I'm doing; I'm not going to hack into the computer, I'm only using a computer somewhere else.

I'm in the middle of installing 13.10 and the Ubuntu page I was following on how to install from a USB stick says nothing about these two choices (on the Installation type screen):     1) Encrypt the new Ubuntu installation for security (you will choose a security key in the next step).      2) Use LVM with the new Ubuntu installation (this will set up Logical Volume Management. It allows taking snapshots and easier partition resizing)   I'm a writer using the computer for mostly writing ebooks but I also do all the things most people do: buy stuff online, online banking etc. I want my information to be safe but I don't want to overburden my system with security stuff either. And I've read a lot of the similarly themed questions here on the forum but they've all been about stuff more technical than I'm concerned about.   Can somebody please just tell me in real layman's terms about the implications of these two choices? Thank you.

My initial problem was that my computer wouldn't let me login to my account. It seems to shut down after I enter my password. I can login as a guest.  I found fixes but I can't remember / figure out my login for access after I hit Ctrl+Alt+F1 and most of the fixes for finding your login username depend on you having access to your account.  I thought the login was the name which appears on the screen when I start the computer normally, but this has not worked, is there another way to find out my username while being effectively locked out of my root-user profile?  I am also assuming that the password is the same one I always use.  Conversely, if the name which appears on the screen at startup and my normal password should have worked, is there another explanation for why I am not able to login on the black command screen.

I'm very new with Ubuntu and generally with linux. I saw ubuntu and it seems like this OS is really good and stable, and so I decided to install it alongside my windows 7 OS.  I have a few problems with the installation. Here is what I did:   I downloaded the 64bit version from Ubuntu official website, and burned it on a dvd. I set the boot sequence to first load from my CD-Rom. Ubuntu installation started, and I chose "Install Ubuntu" in the menu. (where there is also a "Try Ubuntu" option) I clicked forward until I got into the installation type screen    As you can see, the installation wont show my actual details about my hard drive! I have 1 hard drive with 750 GB - 80 GB - My main drive with windows 7 OS 600GB - All of my stuff 20GB Free space that I saved for Ubuntu But the installation wont show that!

When I first installed Ubuntu I choose NOT to ask me for a password at login. That was ok for that moment cause it didn't ask me any password at login. But now I want to be asked for a login password. I changed the settings to Not start automatically but it doesn't work. My Ubuntu doesn't ask me password at login. What should I do now?  In the automatic login box (in the user accounts setting window) I have it checked to off (0 or Off), the thing is that my LightDM login screen gives me only a "Start Session" button below my user name, instead of the usual password field.

Just installed a minimal ubuntu 12.04, then installed xfce4 and xinit from the command line after first boot.  Totally vanilla installation afaik.  I'm noticing that sudo caches the password until I issue sudo -k to clear it.  This is unexpected behavior in my mind.  I've run xfce4 before and don't recall credential caching being on, nor have I experienced it in the many previous ubuntu installs I've had over the years.  Is this a new feature of Ubuntu?  Is this something that's the result of the minimal install?  Is this an xfce default that's been added recently?

I am new to Linux and Ubuntu. When I don't know how to do something with this OS I search on the web and Ask Ubuntu and always find the answer.  But sometimes it's not a great answer nor complete tutorial. I follow the instructions anyway, but I don't know what all the commands mean.  So my question is:   When I follow a tutorial, am I 100% safe? If not, then how can I tell I am in danger?

My Ubuntu 16.04 hangs on shutdown/restart requiring me to press and hold the power key to turn the machine off... I don't know how to report this as a bug and what commands to run to show the necessary hardware/sys log info? Any help would be hugely appreciated!

My PC was working yesterday without any problem. I shut it down and tried to open this morning. It prints out these messages on the black screen:  systemd-udevd[713]: failed to execute '/bin/systemctl' '/bin/systemctl start --no-block nvidia-persistenced.service': No such file or directory  systemd-udevd[852]: failed to execute '/bin/systemctl' '/bin/systemctl stop--no-block nvidia-persistenced': No such file or directory   It then continued with the login screen. I entered my password and pressed enter. It waited for a while and the login screen reappeared again.  How can I fix the problem?

Can anyone walk me through the process of installing Bitcoin on Ubuntu? I'm new to linux, and this is really all I want to do with this computer.
