`apt.debfile` — Classes related to debian package files¶

The apt.debfile provides classes to work with locally available debian packages, or source packages.

Binary packages¶

class apt.debfile.DebPackage(filename=None, cache=None)¶

A Debian Package (.deb file).

The DebPackage class is a class for working with ‘.deb’ files, also known as Debian packages.

It provides methods and attributes to get a list of the files in the package, to install the package and much more.

If you specify cache it has to point to an apt.cache.Cache() object.

Changed in version 0.7.9: Introduce all new methods (everything except for open() and filelist)

VERSION_OUTDATED = 1¶

VERSION_SAME = 2¶

check(allow_downgrade=False)¶: Check if the package is installable.

check_breaks_existing_packages()¶: check if installing the package would break exsisting package on the system, e.g. system has: smc depends on smc-data (= 1.4) and user tries to installs smc-data 1.6

depends¶: List of packages on which this package depends on.

filelist¶: return the list of files in the deb.

install(install_progress=None)¶: Install the package.

missing_deps¶: Return missing dependencies.

open(filename)¶: open given debfile

Return True if a given non-virtual package is replaced.
