    cannot make changes to hard drive

    Hello,
    I am new to Linux, kubuntu etc. Last days i tried to install Linux several times. First i tried archlinus with kde, now i have installed Kubuntu 14, and i have also tried kubuntu 15. Till now in all versions of Linux i get error messages when trying to launch applications or do anything at all.
    The error messages are like: Configuration file "/home/user/.kde/share/config/[application]" not writable. Please contact your system administrator."
    I also cant do anything in the Konsole, if i want to change to su, it says "Authentication failure".
    It looks like the system can't make any changes to the hard drive at all.
    I have now set the bios to load-fail defaults. But that does not change anything.
    Searched the internet about this problem, but couldn't find anything similar to this problem.
    can anyone help me out?

    1. Please specify your computer

    - Brand name and model
    - CPU
    - RAM (size)
    - graphics chip/card
    - wifi chip/card

    2. Are you running Windows or MacOS now? In that case, do you intend to keep it (and have a dual boot system)?

    4. How did you try to install Kubuntu?

    - Did you check the md5sum of the iso file?
    - Which tool did you use to make a DVD or USB drive bootable with Kubuntu?
    - Does it run live (booted from the DVD or USB drive without installing)?

    you should not get issue using the graphical mode (if your user session is active); but from a terminal, use 'sudo' to get rights privilege

    Re: cannot make changes to hard drive

    If the Linux partition on the hard drive has any errors, it will be marked read-only. That sounds like what is happening here. Try this:

    1) When you get the boot menu, choose the recovery mode option.
    2) You'll eventually see a menu; choose "root shell."
    3) Now enter these commands, one per line, at the "#" prompt:
    Code:
    cd /
    mount -o remount,rw /
    touch /forcefsck
    Now reboot. The system will run a file system check when it starts up. Does that solve your problem?

    Note there is no space after the comma in "remount,rw".
    If you ask for help, do not abandon your request. Please have the courtesy to check for responses and thank the people who helped you.

    Check the permissions in that directory and post the output here. Your user should be the owner of all directories/files and have rw permissions.

    Code:
    ls -l /home/user/.kde/share/config/[application

    @seijisensei. Fsck did run, but it did not fix the problem.
    @Sudodus. You are right, I didn't check the md5, I never heard of it before, so I skipped it. After doing the check the codes seem to be invalid. So it is really my fault, sorry for the time it took from you.
    Now I try to download the ISO again. Do you have any idea how I can avoid this problem? Just re-downloading till the md5 does match? I don't even know really what md5 is, and what is essentially going wrong.

    Took me two more times to download, but now I have one with the right sum. Looks like downloading from mirror works better then torrent.

    @Yancek. I did the command with /home/user/.kde/share/config
    Looks like that is the folder where the configuration files of different applications are.
    I can't copy and paste them here with my Linux desktop, because I almost can't do anything with the Linux desktop. But almost all the configuration files have -rw-------
    Only five of the total of about 40 have -rw-rw-r--

    Often but always it works faster with torrent. And the torrent clients ususally check for the md5sum automatically as part of the process. But now you have a correct iso file, so that's fine.
