scripts/cmdeploy run.. ’--> Starting operation: Install Dovecot’ ends in unmet dependencies.

[AspireSus]

Hallo Delta Chat Maker,

on a VPS (Contabo) with OS Debian12 the deploying breaks with:

[.] The following packages have unmet dependencies:
[.] dovecot-core : Depends: libc6 (>= 2.36) but 2.35-0ubuntu3.9 is to be installed
[.] Depends: libzstd1 (>= 1.5.2) but 1.4.8+dfsg-3build1 is to be installed
[.] dovecot-imapd : Depends: libzstd1 (>= 1.5.2) but 1.4.8+dfsg-3build1 is to be installed
[.] E: Unable to correct problems, you have held broken packages.
[.] Error: executed 0 commands

I try with all images provided by contabo, with ;/configure, make.. my own packages, nop.

Now I got a running mailcow-server (without mailadm) following the deprecated delta.chat/de/serverguide.

Can you give me the output of apt update?

And what does lsb_release -a say?

[AspireSus]

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.5 LTS
Release: 22.04
Codename: jammy

[missytake]

Hm... if it looks like Ubuntu and talks like Ubuntu and acts like Ubuntu, maybe it isn't actually Debian ;) Contabo is weird as fuck. I recommend to try again with Debian 12, making sure it is actually Debian 12, and hope that the issue vanishes then...

[adbenitez]

maybe a human/client error, and you accidentally selected Ubuntu instead of Debian 12, not discarding the possibility of an error in the Contabo UI/wizard 🤣

[AspireSus]

I was confused, sorry, Debian 12 was one the images i used, Ubuntu 22.04 is the one with a running mailcow without mailadm. Debian 11, 12, Ubuntu 20.04, 22.04 always produce the package error.

[missytake]

Hm, can you send us what the error looks like on a Debian 12 machine, so we can check which dependency versions are unavailable on Contabo VPSs?

[AspireSus]

No, too much log from too much try and errors, please excuse me for wasting your time.

[missytake]

Okay :) don't worry, investigating servers is never wasted time.
