Installation failes - No installation candidate (dovecot-core and ifupdown)

**major** · Apr 25th 2018

Hi,

I'm installing i-MSCP 1.5.1 on a new server (Debian 9.4) and get the following error:

autoinstaller::Adapter::DebianAdapter::installPackages: Couldn't install packages: Reading package lists...Building dependency tree...Reading state information...Package ifupdown is a virtual package provided by: netscript-2.4 5.5.1 ifupdown2 1.0~git20170314-1

Package dovecot-core is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another sourceHowever the following packages replace it: dovecot-sieve dovecot-ldap dovecot-dev

E: Package 'dovecot-core' has no installation candidateE: Package 'ifupdown' has no installation candidate

I am able to install these packages manually (ifupdown from stretch repo (with a bug warning) and dovecot-core from backports), however, even after installation of the packages and disabling 10apt-listbugs I still get the same error when running the installer.

Is there a known issue? What can I do to omit the installation of these packages by the i-MSCP installer?

Regards, Sven.

Description-en: secure POP3/IMAP server - core files
Dovecot is a mail server whose major goals are security and extreme
reliability. It tries very hard to handle all error conditions and verify
that all data is valid, making it nearly impossible to crash. It supports
mbox/Maildir and its own dbox/mdbox formats, and should also be pretty
fast, extensible, and portable.
.
This package contains the Dovecot main server and its command line utility.

Both packages should be available. Note that we have installed i-MSCP 1.5.1 several times on Debian Stretch without any problem. The problem is on your side. You should check your /etc/apt/sources.list file and also any file from the /etc/apt/sources.list.d directory.
