Hi,

so I am building a Debian 12 VM template with cloud-init. I basically have everything working already, except the automatic resizing for the disk. When trying to run sudo growpart /dev/vda 5, it fails because of No space left on device..

Here is the full command output:

Code: 
ciuser@debian:~$ lsblk

ciuser@debian:~$ sudo growpart /dev/vda 5
attempt to resize /dev/vda failed. sfdisk output below:

Does anyone know how you can fix this?
 
Well managed to work around it by simply installing Debian without LVM and adding a swap file instead of a partition in the end. Here are my preseed and cloud config files for anyone who needs it later :)
