Setting up procps (1:3.2.8-9) ...

Configuration file `/etc/sysctl.conf'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : background this process to examine the situation
The default action is to keep your current version.
*** sysctl.conf (Y/I/N/O/D/Z) [default=N] ? dpkg: error processing procps (--configure):

Errors were encountered while processing:

Anyone can help please?

If i restart script it stopped at the same point .... what can I do about it?

Thanks...

I suggest you continue installing manually, start with the kernel, then reboot and do the rest.

Start here: http://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_Squeeze#Install_Proxmox_VE_Kernel
(install the kernel, reboot and then try to install the rest of the packages as described in the article)

alternatively, you can do a clean install from ISO and restore VM´s from backup.

Hi Martin,

A clean install at this point I think it's the best method.

Sadly I discover that I have no backup for my VM, we have a NFS volume for backups but is not responding right now so I cannot access to backup.

Now the installation ir disrupted so I havo no VM backup tools available!!!

Can I copy var/lib/vz/images files?

Here are already my VM raw files!

Sorry, but I'ìm really in trouble ....

tom · Apr 14, 2012

do you have only KVM guests?
if yes, just copy all VM disks and also all config files inside /etc/qemu-server/

as soon as you got this on backup, you can try the way described.

Hi,
copy the configs (/etc/qemu-server/ for kvm and /etc/vz/conf for openvz) and the vm-data from /var/lib/vz (don't forget iso-images if important).

Udo

andrea68 · Apr 14, 2012

yes just have a couple KVM guests.

Do you think the upgrade process will be broken at this point?

andrea68 · Apr 14, 2012

Ok Udo, I have only KVM guests so I copy ISO's /etc configuration files and vm-data...

andrea68 · Apr 14, 2012

I'm sorry, i'm little bit lost: what way?

tom · Apr 14, 2012

I do not know your setup, network or server infrastructure but I highly recommend you make a backup of your VM data before your proceed.

e.g. on a NFS server, but I do not know if you have one in your network.

udo · Apr 14, 2012

Hi,
perhaps it's help if you install the package which contain sysctl.conf manualy?

Code:

apt-get install procps

Here you can answer to the question, and try after that the script again?

Udo

andrea68 · Apr 14, 2012

I have one single server, 1.9 proxmox, the NFS backup server is unreachable, I backup the VM on an external HD ext3.

The proxmox is a master cluster with no nodes (it was a 2 cluster system, but second server goes away months ago so i remove from cluster the old node).

Here I have 3 KVM guests...

I try script upgrade as I said in firts post with no luck

andrea68 · Apr 14, 2012

Sorry, the output is in italian.

Is say that /etc/sysctl.conf was modified by me o by script after installation, so I have this options:

Y o I : Install new version
N o O : Mantain old version
D : Show differences between verisons
Z : Suspend this process and try to debug...

File di configurazione `/etc/sysctl.conf'
==> Modificato (da te o da uno script) dopo l'installazione.
==> Il distributore del pacchetto ha fornito una versione aggiornata.
Cosa decidi di fare? Le tue opzioni sono:
Y o I : per installare la versione del responsabile del pacchetto
N o O : per mantenere la versione correntemente installata
D : per mostrare le differenze tra le versioni
Z : per sospendere questo processo ed esaminare la situazione
L'azione di default ? di mantenere la tua versione corrente.

If I try with "D" i have:

If you don't have improofments (network, like iscsi) simply install the new version.

Udo

andrea68 · Apr 14, 2012

Ok: I have an iSCSI Qnap server, can I add lately after installation?

Just to be shure:

- I Backup manually (cp comand) all 3 KVM guests (/var/lib/vz/images) on an external USB drive EXT3 formatted
- I Backup /etc/qemu-server/ on the same drive
- I Backup ISO repo's

It's all? I forget something?
What about restoring method?

So many thank you for the patience....

udo · Apr 14, 2012

Hi,
with new version i mean the new version of sysctl.conf!

Udo

andrea68 · Apr 14, 2012

LOL: sorry i misunderstand!

I'll try as soon I can!
Maybe it's best wait to finish my copies....

BTW
I have this iSCSI qnap, you said that maybe can be a problem...
