<![CDATA[Cloudron install error (dpkg error)]]>Hi guys,

I've just wanted to install Cloudron on a new Server, but it can't finish the installation.

Here's the error message:

Fehler traten auf beim Bearbeiten von:
 resolvconf
needrestart is being skipped since dpkg has failed
E: Sub-process /usr/bin/dpkg returned an error code (1)

To be honest; I'm quite inexperienced with running a webserver (that's why I chose cloudron), so I really hope, someone can help.

The server runs Ubuntu 22.04.3 lts (jammy jellyfish) - minimal. (Maybe the minimal is the problem here?)

best
David

Just installed cloudron this day with the new setup-script. For the people reading this in the future) setting the immutable bit did the trick, no installation like I supposed needed. Works like charme...

I expect the Cloudron install script to work if you run the command "chattr -i /etc/resolv.conf" before starting it

@girish The VPS have generally AVX not enabled it's only supported by the RS line a supporter of Netcup told me... Maybe this should be mentioned on the list of cloudron providers...

Luckily, I managed to reproduce this already by simply commenting out the AVX check. Debugging...

Reading the post made me remember that not that long ago I also made a new installation on a Netcup RS 2000 G9.5 with their normal Ubuntu image. It did not complain that resolfconf was missing, but instead that /etc/resolv.conf was marked immutable. Since he makes the file readable in his snippet I think @m-si ran into the same issue.

@m-si what server type are you using on Netcup?

It makes the DVD full installation of Ubuntu obsolete (and solves the issue of the OP) and reduces the maintenance burden of Netcup RS server customers... with approval I thought of confirmation on a different system by a different user than me. Sorry for the confusion have to work on my english skills 😉

I have never tried to install with DVD and only used the Cloudron providers, so have not hit the issue.

What do you mean?

So it produces a error like this :

Fehler traten auf beim Bearbeiten von:^M
resolvconf^M
needrestart is being skipped since dpkg has failed
E: Sub-process /usr/bin/dpkg returned an error code (1)

To fix it. resolvconf needs to be installed manually with these commands.

sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install -y resolvconf
sudo chattr -i /etc/resolv.conf && \
sudo dpkg --configure resolvconf

and one can proceed happily with the installation, without needing to use the full Ubuntu DVD. Can someone approve this fix?

I've got as far as selecting the Ubuntu DVD but now I can't login!

Aha, I found this https://ubikann.com/2021/09/21/installing-ubuntu-server-20-04-lts-on-a-netcup-root-server/ which directed me towards installing the DVD using the VNC screen via the Netcup Server Control Panel.

I managed to use that (but you're right, not exactly simple) to install full Ubuntu and am now installing Cloudron...

Maybe you should delete Netcup from your docs on this page: https://docs.cloudron.io/installation/#install_1 – as it does not seem to be that simple to install.

Agreed. There used to be a Cloudron image you could choose, but it doesn't appear to exist any more.

And I can't even work out how to install the full Ubuntu on Netcup! It's very frustrating.

I've got as far as selecting the Ubuntu DVD but now I can't login!

How did you do it @David-0 ? Thanks!

Maybe you should delete Netcup from your docs on this page: https://docs.cloudron.io/installation/#install_1 – as it does not seem to be that simple to install.

I'll try to install Ubuntu server. (not minimal)

Version 22.04 is correct though.
