I seem to have unintentionally deleted almost everything from Ubuntu using   apt-get remove libc6 libc6-dev   Is there any chance I can get my files back (with Ubuntu) or will I have to reinstall Ubuntu?

I have removed the mentioned libraries. Then my system disconnected from NIS service and many packages are being removed. The problem is I am not even able to login in my system. When i restarted it is showing "low graphics mode error". I do not know what to do Please help me. I am a beginner to Ubuntu.

I have 3 partitions: one for Windows 7 (ntfs), one for Ubuntu (ext4) and one just for data (ntfs so both operating systems can see them).  My problem is that I had stored some files on the data partition using Ubuntu and when I booted Windows 7 all that data was gone! After that I couldn't find the files even when using Ubuntu.  My files were simply GONE :(  Is there something I can do in Ubuntu or is it just windows problem?

I accidentally lost some of the system files by executing the following command in the terminal:   sudo apt-get purge wine\*   Most of the installed software (terminal, software center, libreoffice etc.) are now lost.  Does anybody have a solution for this issue?

I know this may sound stupid, but I was having a problem with my ubuntu, it wasn't loading.   So I was googling solutions and one of them was purging something and installing something   so I did it. The proccess took a couple hours, and it didn't work. It turns out it was something to do with my graphics card (which I fixed), but when I loaded it up, I had lubuntu.   Is there any way of reverting back to ubuntu?   Or is lubuntu better to keep? I have no idea, please help.

I usually back up before formatting and doing a re-installation of Ubuntu, it was in the process and then obviously stopped prematurely but I was thinking all my data was transferred.  After installing formatting the drive and sticking a fresh Ubuntu on there I proceed to transfer the files from my memory stick to my hard drive, some files are there but most of my 6 years worth of pictures are gone. Is there any way I can get these back? I don't know what to do, I feel absolutely crap :/  Any help would be very appreciated.

I'm trying to figure out a way to get a list of the packages that are no longer available in the repositories that I have enabled. This workstation has been through quite a few versions of Ubuntu and has had many 3rd party repositories added and removed. I'd like to get a list of software that I have from these removed repositories, so I can clean it up or add back the appropriate repositories.

I just deleted a file in Nautilus with Shift+Delete, which warned me that "If you delete an item, it will be permanently lost." I wonder if there is no way to recover the file?  My OS is Ubuntu 10.10.

Problem I Faced  I installed something that crashed my Wifi drivers that I compiled earlier. Un-installing the same package doesn't helped. Finally, I re-compiled my wifi drivers and things are good.  My Question But, is there anything like System Restore or System Rollback in Ubuntu/LinuxMint?  Is there anything that can undo an apt-get install package command?

Where can I find the location of downloaded .deb files?  I want to copy this folder before I reinstall Ubuntu so I don't have to redownload the packages.  I am running Ubuntu 12.10 32-bit.  How can I do this?

I was compiling a tool called Rejoystick so I installed a few packages and dependencies. But now I don't need it any more so I removed those packages. Running apt-get shows that I have some packages that are automatically installed and are no longer needed.   But I have a bad experience with apt-get autoremove. It broke my desktop environment when I uninstalled wine some time ago. Luckily, I had a clonezilla partition backup then, but this time, I don't have a backup. So I'm cautious. Running apt-get shows these packages are orphaned     gir1.2-gtk-2.0 libasound2-dev libavahi-client-dev libavahi-common-dev   libcaca-dev libcairo-script-interpreter2 libdbus-1-dev libdrm-dev   libexpat1-dev libfontconfig1-dev libfreetype6-dev libgl1-mesa-dev   libglu1-mesa-dev libharfbuzz-dev libharfbuzz-gobject0 libice-dev   libpcre3-dev libpcrecpp0 libpixman-1-dev libpng12-dev libpthread-stubs0-dev   libslang2-dev libsm-dev libx11-dev libx11-doc libx11-xcb-dev libxau-dev   libxcb-dri2-0-dev libxcb-dri3-dev libxcb-glx0-dev libxcb-present-dev   libxcb-randr0-dev libxcb-render0-dev libxcb-shape0-dev libxcb-shm0-dev   libxcb-sync-dev libxcb-xfixes0-dev libxcb1-dev libxcomposite-dev   libxcursor-dev libxdamage-dev libxdmcp-dev libxext-dev libxfixes-dev   libxft-dev libxi-dev libxinerama-dev libxrandr-dev libxrender-dev   libxshmfence-dev libxxf86vm-dev mesa-common-dev x11proto-composite-dev   x11proto-core-dev x11proto-damage-dev x11proto-dri2-dev x11proto-fixes-dev   x11proto-gl-dev x11proto-input-dev x11proto-kb-dev x11proto-randr-dev   x11proto-record-dev x11proto-render-dev x11proto-xext-dev   x11proto-xf86vidmode-dev x11proto-xinerama-dev xorg-sgml-doctools xtrans-dev   zlib1g-dev   I'm not sure if I should run apt-get autoremove. I was searching details related to each of these packages so that I can understand which ones are needed but they all seem important e.g.     gir1.2-gtk-2.0    I have Cinnamon, GNOME and Unity installed, I think apt-get autoremove will break something. Any help will be appreciated.   Thanks for reading.

I've been building my own Linux distro, and I've stripped the binaries, etc. The system won't use GCC or development tools, as it will be a Chrome kiosk, so it would greatly help if I could strip down the system...  I was wondering, is there a way that I can delete all of the unused system files (like binaries, etc.) by watching what files/libraries are used during runtime? Maybe another method is preferred, but is there a way to accomplish something like this?
