Could not write bytes: broken pipe

[rqr]

Hello,
I cannot boot my computer and the "Could not write bytes: broken pipe" message appears.
Some information:
Computer: dell with nvidia. Ubuntu 12.04LTS 64 bits

Disk /dev/sda: 640.1 GB, 640135028736 bytes
255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Partition table entries are not in disk order

I've tried without any success.....

Through the recovery mode: Repair broken packages.

By Purging nvidia and re-installing it again

rm .Xauthoroty didn't work

I tried to use the nano editor (sudo nano -w) to delete a supossed failed var/lib/dpg/status and didn't know how....

At the moment, I'm using this live-cd to try to solve this.

Thankyou.

I saw "Could not write bytes: broken pipe" message on an 12.04 server that booted and worked perfectly. There's a bug in Plymouth but it's supposed to be a cosmetic issue.

So there's a good chance this message has nothing to do with why your PC doesn't boot. You should mount the root partition from your installation while you're in Live environment and check if there's anything interesting in /var/log/dmesg or /var/log/system there.

Thanyou. Could you tell me step by step how to do it?

Finally I've done this:
ubuntu@ubuntu:~$ sudo mount /dev/sda6 /mnt
ubuntu@ubuntu:~$ ls /mnt
lost+found rqsal
ubuntu@ubuntu:~$ sudo mount /dev/sda7 /mnt
ubuntu@ubuntu:~$ ls /mnt
bin initrd.img mnt srv
boot initrd.img.old opt sys
cdrom lib proc tmp
C:\nppdf32Log\debuglog.txt lib32 root usr
dev lib64 run var
etc lost+found sbin vmlinuz
home media selinux vmlinuz.old

Does it help???

Your installation appears to be on /dev/sda7. You need to go into var/log subfolder:

cd /mnt/var/log

and then check log files, say:

tail -200 dmesg # outputs last 200 lines, increase the number if needed
tail -200 syslog

See if you can find any obvious error messages. If unsure, post the output here but wrap in [code] tags because otherwise it's very annoying to read.

Well, your dmesg log looks fine. Could you post syslog as well? And what exactly happened during boot after that "broken pipe" warning? Did you get logon prompt? Blinking cursor? Blank screen?

[rqr]

Your installation appears to be on /dev/sda7. You need to go into var/log subfolder:

cd /mnt/var/log

and then check log files, say:

tail -200 dmesg # outputs last 200 lines, increase the number if needed
tail -200 syslog

See if you can find any obvious error messages. If unsure, post the output here but wrap in [code] tags because otherwise it's very annoying to read.

Hi, I've found this cuts....

I don't know if this information would be enough and I don't know how to wrap the information in codes, as you said before. I'm Sorry, I am a real absolute beginner

[rqr]

Well, your dmesg log looks fine. Could you post syslog as well? And what exactly happened during boot after that "broken pipe" warning? Did you get logon prompt? Blinking cursor? Blank screen?

How shall I extract the syslog?

After that broken pipe stuff nothing happens, and I cannot do anything apart from entering by pressing ctrl Alt F1 buttons.

Well, if you see command line logon prompt then most probably it's a video driver issue and most probably the issue was caused by a kernel update.

D/l the latest nVidia driver, put it somewhere on sda7, reboot to your installation, navigate to the folder where you put the script and run the script:

sudo sh ./NVIDIA-Linux-x86_64-319.23.run

Follow the instructions and reboot again when the installation is complete.
