After installation Debian boot is stuck at this stage

[asifnaz]

Hi ,
I have installed Debian 11 on my PC . Upon booting it stuck every time .
Please help

[FreewheelinFrank]

ifupdown has been replaced by netplan, it seems.

I noticed the "failed" message for ethernet, which is not connected on my laptop, but apparently if there is no internet connection at all, boot can stop.

There is a solution here with an edit to the config file to tell netplan the connection is not essential to boot.

[asifnaz]

so I need to edit /etc/netplan/01-netcfg.yaml

and add line optional: true

after that as root

netplan try

netplan apply

please confirm as I am not very expert

I use debian 11 on my server upgrade from Debian Buster and Debian Bookworm on my VM upgrade from Debian Bullseye there is no netplan implementaion.

in such case suggestion provided by FreewheelinFrank will not work..?

[FreewheelinFrank]

OK, I checked and I couldn't find the netplan folder, so it looks like this change hasn't happened in Debian.

I noticed the "Failed" message for my ethernet and assumed something had changed, but obviously I was wrong. Sorry.

It must be something else preventing boot. I will have a look in a bit.

Do you have anything in

Code: Select all

/etc/network/interfaces.d/setup

?

The Live installer seems to be adding some entries which try to bring network interfaces up a boot time.

Mine has

Code: Select all

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

I am going to try removing these.

Source ?

I noticed the "failed" message for ethernet

I do not see any "ethernet" mention in the screen shot.

@ afiadi :
What is your screen shot supposed to show ?
The netplan executable is in /usr/sbin, so "which" run as a normal user won't show it.
The output of "ip addr" does not tell what manages network interfaces.

@ asifnaz :
Please do not uselessly quote pictures and full messages.

IME, failure of the "networking" service does cause boot hang. This failure may be caused by a bogus /etc/network/interfaces.d/setup file, to be deleted.

Maybe you should pay attention to the next to last line saying that the display manager started. Then the graphical login screen should be displayed next. If it does not happen, it may be a graphic driver issue.

What does "lspci -nnk" show about the GPU ? If AMD/ATI, did you install the package firmware-amd-graphics ?
What happens if you boot in recovery mode (no graphics, no network) ?
What happens if you boot in normal mode but with parameter "2" added to the kernel command line (no graphics) ?

Source? Assumption I'm afraid - already retracted and apologised for.

For me it was Ethernet:

Code: Select all

# journalctl -u networking.service --no-pager

[FreewheelinFrank]

I commented out these lines in the file above and for me the attempts to bring up network interfaces (and the "failed" messages) have stopped. Maybe that will be the answer for you too.

Code: Select all

#auto lo
#iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

?
The Live installer seems to be adding some entries which try to bring network interfaces up a boot time.

I do not see any evidence that this file is created by the live installer Calamares in the links you posted (even though I heavily suspect it, because I never observed it with the classic installer - but never used the live installer).

No, I have no evidence other than I used the live/non-free installer and I certainly didn't put those entries there.

yes i have those lines . i commented them but still cant boot

[FreewheelinFrank]

Do you still have the two [FAILED] network messages?

If you have removed the cause of the networking service failures, move on to p.H's advice, namely:

IME, failure of the "networking" service does cause boot hang. This failure may be caused by a bogus /etc/network/interfaces.d/setup file, to be deleted.

[asifnaz]

in recovery mode i can boot into gui using startx

[p.H]

Can you do it too after running

Code: Select all

telinit 2

in recovery mode and logging in ?
Then it looks like sddm is part of the problem.
