What is it?

Cupt is a partial re-implementation of APT suite from scratch.



The first announcement is here. Also, on debian-devel-announce.

What infrastructure does Cupt use?

It uses the same APT infrastructure, e.g. index files, deb cache archive files, configuration files. It understands some of widely used APT options.

What features Cupt has?

What important features Cupt doesn't have?

Can I use Cupt along with libapt-based package managers?

Yes, you can mix apt-get/apt-cache/aptitude/etc. with cupt without bad consequences.

How to feedback?

Why Cupt can't parse the configuration file /etc/apt/apt.conf.d/00CDMountPoint?

If you see the error like

E: syntax error: line 4, character 1: expected: semicolon (';')
E: unable to parse the config file '//etc/apt/apt.conf.d/00CDMountPoint'
W: skipped the configuration file '//etc/apt/apt.conf.d/00CDMountPoint'

then you have a buggy configuration file which doesn't follow the syntax rules from apt.conf(5). It misses the ';'. Here's how this file should be corrected:

Acquire::cdrom {
  mount "/media/cdrom";
Dir::Media::MountPath "/media/cdrom";

Notice the semicolon in the end of the third line.

Why 'cupt update' fails with 'no download handlers available'?

If you have http/ftp mirrors in your sources.list(5) and see the error like

Fail:1 no download handlers available

from cupt update command, you have to install one of the packages libcupt2-0-downloadmethod-curl or libcupt2-0-downloadmethod-wget. One of these packages should have been installed by default unless you switched off installing Recommends or modified the configuration in some another way which prevented libcupt download methods from being automatically installed.

Current/stable branch

The stable branch is 2.x (master in the Git repository). Implemented in C++11, consists of a runtime library, download method plugins and a console front-end to them. Debian Wheezy contains 2.5.x.

The HTML version of the latest tutorial may be found, apart from the binary packages, here.

Old stable branch

The 1.x branch was written in Perl. This is the branch which went to Debian Squeeze.
