The relevant error is just above the first line of your screenshot.

 

[JeanBro]

Do you know how to fix.
I tried to configure dpkg and it’s put me this error

Hi,
did you setup the apt sources.list correctly? You can follow this guide for a setup on top of Debian 11
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye

Please also provide the commands you are running so one might grasp whats going on more easily

 

[JeanBro]

I follow all the step that is in https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_11_Bullseye
But a the end when I do apt install proxmox-ve postfix open-iscsi it is making the error that you can see in the first screenshot after that I tried to fix the error Sub-process /usr/bin/dpkg returned an error code (1) while doing this command : dpkg --configure -a and it is making the error that you can see in the second screenshot.
Thank you very much for your help

Try to reconfigure already installed packages with dpkg-reconfigure ifupdown2 open-iscsi pve-manager proxmox-ve and post the output.

 

[JeanBro]

It’s doing that

 

[Chris]

Okay, so try to install only the ifupdown2 package via apt install ifupdown2 and post the output.

 

[JeanBro]

It is the result of apt install ifupdown

 

[Chris]

Try dpkg --configure ifupdown2 and check your /etc/network/interfaces. The error suggests that you have no vmbr0? What's the output of brctl show and cat /etc/network/interfaces and /etc/network/interfaces.new

 

[JeanBro]

For cat /etc/network/interfaces it is showing that :

 

[JeanBro]

So there is a vmbr0

 

[UdoB]

So there is a vmbr0

You may want to add a physical interface (your eth0) to that bridge...

See https://pve.proxmox.com/pve-docs/pve-admin-guide.html#sysadmin_network_configuration for an example.

 

[JeanBro]

So what do I need to do

 

[Chris]

So what do I need to do

It seems to me that the ifupdown2 configuration fails because there is no vmbr0 (therefore I asked for brctl show). So either you create the bridge and try the configure again, or you adapt you /etc/network/interfaces

I make the bridge and I did again apt install proxmox-ve postfix open-iscsi and at the end it put me that
And that is for brctl show :

Okay, so it seems to make progress, as now only the open-iscsi post-install script is unhappy...
Can you perform a systemctl stop iscsid.service followed by a ps aux | grep iscsid. If there are processes other than grep iscsid, try to kill them with killall -9 iscsid and then try to reinstall the package.

Not working same error

 

[JeanBro]

When doingsystemctl status iscsid.service
It is showing that

 

[Chris]

According to the error in the log failed to mlockall, exiting... iscsid fails during locking memory pages from being swapped out https://github.com/open-iscsi/open-iscsi/blob/master/usr/iscsid.c#L622

This could be because of low memory or missing permissions. Please check the CapabilityBoundingSet= in the service given by systemctl show iscsid.service, especially for the presence of cap_ipc_lock and also check your current memory usage free -m.
You can also try to invoke the iscsid binary directly and check the output for futher clues /sbin/iscsid -f -d 10

Can you also check the package status dpkg -s open-iscsi
