Notes
- ↑ In case there are unsatisfied dependencies for package_file, yum will try to get and install it from known repositores.
- ↑ 2.0 2.1 Usually it is not necessary to download packages manually and install them. Use apt-cache search name to search for package in configured repositories and apt-get install package to install package and all it's dependencies
- ↑ 3.0 3.1 Use a binary package if it is available from $PKGDIR, otherwise emerge from source as usual.
- ↑ 4.0 4.1 Use a binary package if it is available from $PKGDIR, otherwise abort.
- ↑ This will also remove any packages which depend on the package
- ↑ Package will reside in /var/cache/apt/archives.
- ↑ Package sources will reside in /usr/portage/distfiles.
- ↑ 8.0 8.1 In rpm world, a dependency can be a package name, a file, or a special atom like
perl(IO::Zlib)
for a perl module. In deb world, this can be either real or virtual package name. - ↑ Actualy shows the whole dpendency situation that leads to install this package
