Upgrade Proxmox without Internet.

[FrancisS]

Hello,

I have a Proxmox 5.2.8 and want to upgrade to 5.4.1, the server do not have Internet access.

I mounted the Proxmox ISO on "/media/cdrom" and I tried to use "apt-cdrom" but the iso is not recognized (there is a problem with the one line "Packages" file in "proxmox").

How can I upgrade from the ISO ?


Best regards.

Francis

Hello,

I uploaded screenshot of the "apt-cdrom" errors, the "sources.list" modified manually and the "apt-get" errors.

All the errors are related with the one line file "proxmox/packages/Packages".

Best regards.

You are right, the format of the CD isn't recognized by apt-cdrom. What you can do is go into the dists/stretch/pve/binary-amd64 and proxmox/packages directories and install the .deb files with "dpkg -i" (those that you have installed already - at some point I had some oneliner ready for that ...)

I'm trying to figure out what would be needed to make it compatible with apt-cdrom, maybe you want to file a feature request on bugzilla.proxmox.com for that so that it won't get forgotten?

Actually, I found the culprit. The second Packages file on the CD was missing its linebreaks. We fixed the building tools - the next release should be compatible with apt-cdrom (again). No need to file that feature request anymore.

Hi Rhonda,

Thank you for the fix in the next release (the compatibility problem is also with "apt-get" not only with "apt-cdrom").

Before I see your reply I used "apt-get" to install the deb files from "dists/stretch/pve" and "dpkg -i" to install deb files in "proxmox/packages".

When I used "dpkg -i" and try the resolve packages dependencies I found some dependencies problems.

There is an update for "perl" but not a file for the prerequisite "perl-base".
There is a "libc6-dev" but no "libc6".
There is an update for "ssh" but no "openssh-client".
There is updates for "libgnutls-openssl27" and "libgnutlsxx28" but no "libgnutls30"

I downloaded missing deb files from debian.

Best regards.

@rhonda any chance we could get the fixed Package file?

@rhonda any chance we could get the fixed Package file?

In essence, if you copy the CD to the harddisk, you can change to the proxmox/packages directory and call "dpkg-scanpackages . /dev/null > Packages" in there to create it. That should do the trick for the time being.

Hi,

Thank you !

Best regards.

PS: We need to install dpkg-dev.

Hello all,

I saw this post back when it was version 4.x (https://pve.proxmox.com/wiki/Upgrade_a_4.x_Installation_using_a_newer_ISO_image) and I followed the steps but in the end I get the CDROM cannot be used in apt-get, to instead use apt-cdrom (which I used previously in the steps). I'm trying to get from version 7.1 and 7.4 to 8.0.3 but I'm stuck. I also read this entire post and you mentioned a bug while installing from CDROM for that version/release but the fix was installing all .deb files manually (which I tried and I get dependency/will break this errors) or fixing some file's linebreaks. Is there any new guidance on how to upgrade ProxmoxVE without connection to the internet and using the ISO on a repository or burned to a CD/DVD-ROM? I get to the step where I can see:

deb cdrom:[Proxmox 8.0.3]/ bookworm pve
deb cdrom:[Proxmox 8.0.3]/proxmox/packages/ /

but after this the error is "Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs

I've searched Debian and other Linux Forums to see if I can upgrade without having to erase everything and start over again but no luck. Any help is greatly appreciated.
