Issues upgrading PVE

Hi Proxmox community,

I am having an issue upgrading my OS with a "sudo apt-get upgrade" I've Googled/looked here according to the error message I see and I cannot make heads or tails.
When upgrading I see that the PVE kernel wants to be updated, but it needs to remove the old Debian kernels. When first trying to update I realized that this script was completely missing from my OS so I manually created it: /usr/share/pve-kernel-helper/scripts/functions

After placing that script there, I see there is a "Syntax" error and I am not sure why since I pulled the script from an already functioning PVE machine.
Could anyone point me in the right direction? I am trying to upgrade to the lastest version, here is my current version:

Linux PVE-Hypervisor 5.0.21-5-pve #1 SMP PVE 5.0.21-10 (Wed, 13 Nov 2019 08:27:10 +0100) x86_64 GNU/Linux




This is a log from "sudo apt-get upgrade"

seems some file is corrupted... can you post both those files?
 
Sure here they are:

cat <<- EOF

I have a few VMs installed in Proxmox but nothing major... should I uninstall it then re-install to the latest since it seems corrupt?
If I uninstall will it save the VMs since they are QEMU? I'm hoping I can remove the current version and just update the kernel with the latest.
 
can you please either attach the files directly, or post it with a 'code' tag?

otherwise it garbles some things (e.g. the smilies) and it is not clear if there is something wrong there or not
 
Yeah someone please advise since I cannot remove Proxmox from the system.. Something is very stuck and broken, I guess that's what happens when there is a older Kernel.
 
@hvnoclabs
I'm facing the same issue, if I find the answer - I'll post it here
EDIT:
I think I found it.
Edit this file:
Bash: 
nano /usr/share/pve-kernel-helper/scripts/functions
And take a look around line 65 and remove all spaces/tabs before word EOF, like so:
BEFORE:
Bash: 
        kernels="$(cat <<-EOF
                $running_version
                $install_version
                $manual_kernels
                $latest_2_versions
                $series_metapackages
                $oldseries_latest_kernel
                EOF
                )"
AFTER:
Bash: 
        kernels="$(cat <<-EOF
                $running_version
                $install_version
                $manual_kernels
                $latest_2_versions
                $series_metapackages
                $oldseries_latest_kernel
EOF
                )"

It allowed me to move on, but I faced another problem:
Bash: 
/etc/initramfs/post-update.d//pve-efiboot-sync: 10: /etc/initramfs/post-update.d//pve-efiboot-sync: /usr/sbin/pve-efiboot-tool: not found
run-parts: /etc/initramfs/post-update.d//pve-efiboot-sync exited with return code 127
dpkg: error processing package initramfs-tools (--configure):
installed initramfs-tools package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
initramfs-tools
E: Sub-process /usr/bin/dpkg returned an error code (1)

EDIT2:
I've just copied content from another proxmox and pasted it inside
Bash: 
/usr/sbin/pve-efiboot-tool
then
Bash: 
chmod 777 /usr/sbin/pve-efiboot-tool
(777 is likely dangerous, I know it)
And then just installed what I wanted with no problem.

I'll take a look. Also for your setup check that you have pve-efiboot-sync, if I recall I didn't have this script and I needed to manually add it.
 
Oh my goodness it worked! I just changed the positioning of EOF in the "functions" script. I will now need to work on the full upgrade.
So far so good!
