    Ubuntu will not boot

    http://paste.ubuntu.com/1456479/

    I have been getting messages that my home directory has been full. I now am unable to boot. I have tried to delete files in my home directory using Ubuntu 12.10 remix and repair my GRUB but have been unsuccessful. See link above.

    I have logged on using 12.10 which I have on another drive.

    System:

    Desktop AMD64
    160G drive with 12.04
    160 drive with 12.10

    2G RAM

    It is not just /home but / (root) as sda1.

    /dev/sda1 ext4 49G 46G 332M 100% /media/ubuntu/741f375b-2561-44ff-9875-9fcd13a43c9c
    Since you have a separate /mnt/data are you not putting most data into your data partition? I use 25GB system partitions including /home and have about 9GB used. But I link all the standard user folders like Documents, Music etc to my data partition so they automatically are in data partition.

    Caution deborphan will delete anything you manually installed. See comment:
    Better to use Synaptic to select the ones you no longer want. Also you get notified about dependencies to be removed and can reconsider, if need be.

    # empty trash
    # remove log files if no issues
    cd /var/log
    sudo rm -f messages.*
    sudo rm -v /var/log/*.gz


    Mount your sda1 and use these to check for large files or folders.
    #check for large files:
    sudo du -h --max-depth=1 / | grep '[0-9]G\>' # folders larger than 1GB
    sudo find / -name '*' -size +1G # files larger than 1GB
    find . -maxdepth 1 -type d ! -name . -exec du -sh '{}' \; | sort -h
    dpkg-query -Wf '${Installed-Size}\t${Package}\n' | sort -n
    gksudo nautilus /root/.local/share/Trash/files # Be sure to enable viewing of hidden files.

    Thanks for getting back to me Fred. I did create /data directories in another partition and links back to my /home directories. This seemed to work however I found that the files also seem to have stayed in my /home. When I installed the Steam beta I have filled my /home and now it won,t boot. When I look at my /home the data does not seem to there. I have deleted a few unwanted files and have nearly 1G free so I'll try once more with boot-repair.

    I can't get /dev/sda to mount. I get a message: "can't find /dev/sda in /etc/fstab or /etc/mstab"

    you have to mount sda1 ; sda is the hard disk. you mount the partition.

    I seem to have mounted sda1. Using your code, Fred, I get 46G of in my /media. This would account for my problem but I don't know how to delete it.
