big problem after an upgrade 8.04 to 10.04
 

First of all , I'm French and please forgive me for mistakes in English language ...

My server is actually disconnected , so my websites can't be seen by visitors ...

My personnal server shut down when it tryed to upgrade to 10.04

I 've tried many times to restart by ' recovery mode ' but it didn't works

I can have access to my computer by using ' RIP Linux ' cd live ...I can see files and certainly have an action on my computer ...

But , how to rebuild a start boot ?

"Repair" by using 10.04 server live cd doesn't works

I've tryed from the live cd ' RIPLinuX 10.8 ' to boot partition #1 and # 'others ' it doesn't work ...

from boot system when the computer starts by itself , I can read the same message ...

udev[878]: error getting socket : invalid argument

.....

Missing modules (cat /proc/modules; ls /dev)
Alert ! /dev/disk/by-uuid/e9 ........... does not exist

So ... what's the better way to restart it ?

Thank you ...

Have a nice day using Linux ...

Wel-come to LQ
Might be grub not upgrade properly. You should have chosen to grub2 during upgradation.


Boot from Ubuntu live CD and use partition number instead of UUID in kernel line.

MIght this help you.

also look below for same issue.

Maybe...

The universal tool for GRUB is SuperGrubDisk. You can try the live-cd version for GRUB2, the bootloader for 10.04. It might boot the system and may allow you to reinstall the bootloader. It should at least give you some more information to work with.

hello again ...

I've download SuperGrub ...

the computer starts

detect any os : found every os from 2.6-22-14 to 2.6.24-28

Detect any GRUB2 : found Linux on (/dev/hdc1) but if I press ' enter ' the answer is ... error: file not found

and the computer refuse to boot ...


Tank you for your help , may be i have to find how to climb up the next step ? lol

I think your system may be badly broken by the "update" from 8.04 to 10.04. Normally, people go 8.04 -> 8.10 -> 9.04 .... -> 10.04, but even then, they have problems. I know both 8.04 and 10.04 are both "LTS" releases, but the upgrade process seems to be very unreliable.

Your options at the moment:
1] Reinstall your server from a backup (I hope you have one). Get it running again. Meanwhile make a clean install of 10.04 on a new partition, configure it, then gradually migrate your server's databases and whatever to it. Test it. Then you can put it into "Production", and take the 8.04 version offline.

2] If no backup: Make a clean install of 10.04 to a new partition. Configure it. Mount your old partition and migrate your server's databases and whatever from 8.04 to 10.04. Test 10.04, use it.

Bon chance.

Hi Tredegar ...

I have built a new server ( on a new computer ) using 10.04

So I can connect the hard disk of my old server , in slave mode , to the new one ...

may be ' the solution ' ?

one thing, I can't understand how my old server could have this critical problem and ' out of order ' juste for an upgrade ?

( Unbuntu forum said in France , that user 8.04 should wait for 10.04 to upgrade ...., so I wait and do that )

But after 3 hours because of critical temperature of CPU the computer shut down


Thank you for your help

Good.

Yes. But if you do not want physically to modify your old server (unscrew drives...), perhaps just boot it from a "live CD". Then establish connectivity on your LAN. (This is likely to be faster than moving hardware around.)

Then mount your broken partition(s) to the live distro.

Then use ssh or scp or sftp://user@oldserver (in nautilus) nfs or even plain old cp (the choice is yours, choose whatever you are happy with) to move the files you need, over your LAN from the live CD install, which has access to your (broken) 8.04 "personal" files. You do not care about the OS files, as the OS is broken.

Then you'll have [1] A working 10.04 linux installation and [2] Access to the files you need to bring your 10.04 server up to the functionality you need.

If you search the net, you will see many people have had problems. If you think about it (everybody's system will be different in different ways), it is not so surprising.

I have always done a clean install, and then copied my needed files over to the new system. Once I am happy (usually a couple of months) the old version can be retired, re-cycled or thrown out.

Thank you for your help ...

connecting the hard drive in slave mode is not a problem , my broken server was installed on a notebook Asus , and it's very easy to link the hard drive in slave mode to the new server ...

I had not any problem to copy the joomla folders on the new server ...

but copy /var/lib/MySQL. seems to be a real problem ...

So , I think I'll have to create again my websites on the new server ...

Or may be a miracle to restart the old one and make transfert by the usual mode ...

???
