Hi! using the script, ubuntu installs perfectly, however standard login ubuntu/ubuntu is not accepted. Proxmox 8.

[tteck]

Did you follow "Setting up Cloud-Init"?

[AOskam]

Reading is difficult :). Thanks

Hi and thanks for the scripts. They are such a relief.
However, I have the following problem with the Ubuntu VM:
I have run the "Get SSH Going" section, but I cannot connect with PuTTY or Termux via ssh (connecting with root and password). I get the following message: No auth methods could be used.
I do not have this problem with the Debian 12 VM.
Does anything else need to be adjusted in the sshd config or how can I fix the error @tteck ?

[Necrul]

Did you ever figure this out? Running into the same issue here. @tteck

[iz8mbw]

just remove or rename the file 60-cloudimg-settings.conf in /etc/ssh/sshd_config.d

I ran the Ubuntu VM but see no GUI. How do we proceed from here? I am completely new to this.

[JZambranoIT]

It's meant for servers so you won't get a gui. If you want a desktop environment create a vm through the proxmox gui using an ubuntu desktop iso.

Hey I have couple of questions regarding this way of generationg VMs,

1. Why not implament inside the sciprt to use cloud init rather doing it manuly?
2. Is there's a documents on ubuntu image where I can find which pakcages are already installed?

[tteck]

1. The script sets it as cloudinit
   

   Proxmox/vm/ubuntu2204-vm.sh

   Line 411 in cae357c

   -ide2 ${STORAGE}:cloudinit \

2. 🤷🏻‍♂️

Just gonna post here the issue I encountered after I installed that vm (it might help someone who got stuck on different things related to this img).
I had an issue with mounting a cifs shares into this vm, as cifs module isn't present inside the kernal package of this img, so to fix that issue is I found out you had to install extra modules by doing "sudo apt install linux-modules-extra-6.8.0-31-generic" which fixed my issue after a reboot.

[project-blaze]

I am trying to mount the smb share from truenas using latest ubuntu 24.04, but it doesn't work using the configuration below. It always fails. I have already installed cifs-utils and tried the following entry in fstab. I have even tried including the username and password directly.
//192.168.1.21/data /mnt/truenas/data cifs credentials=/etc/samba/.smbcreds 0 0
#//192.168.1.21/data /mnt/truenas/data cifs vers=3.0,credentials=/etc/samba/.smbcreds,uid=1000,gid=1000,defaults 0 0

sudo mount -a
mount error: cifs filesystem not supported by the system
mount error(19): No such device
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) and kernel log messages (dmesg)

Update:
Sorry, I didn't see the solution above. This command solved the issue by the time of posting.

'''sudo apt install linux-modules-extra-6.8.0-31-generic'''
