Upgrade problem

[Alan Weaser]

Hi

 

I am a Linux and Ubuntu novice and have had a RAID home media server working
perfectly for some months (Fiesty I think).  FYI I have often been told I
don’t have permission to access certain files which was annoying as I’m the
only account, but ignored it as I didn’t know how to change settings.

 

My problem occurred when I did the latest “major update”.  During the update
it gave MANY messages stating certain files/directories could not be opened,
which I ignored.  They were there but all stated I was not Root and could
not open them (I used a user account).

 

On reboot, the system gets to the Ubuntu logo and get ¼ way along the bar
then fails.  It fails at “Checking Root file system; fsck: error opening
libdevmapper.so.1.02.1; no such file.  Exit status 127”  When asking for
root maintenance password, I enter the password I always used and it scans
some pages and gives a KABOOM.

 

It states the bug report is
https://bugs.launchpad.net/ubuntu/+source/command-not-found  

I should include 

“No Module names CommandNotFound.  

Traceback (most recent call last) 

File  “usr/lib/command-not-found”, line 10 in module from CommandNotFound
import CommandNotFound.  Import Error: No module named CommandNotFound.
Python version 2.5.1. final o.

Bash: Python: Command not found

 

I then have a prompt “root:Mediaserver1:~#” (MediaServer1 is my machine
name).

 

My question is, if I use a Ubuntu 7.10 Desktop CD to re-install, will I
loose all my existing, valuable data?  Or, can anyone suggest how to get
around my dilemma?

 

Thanks
