Use apt-cache or the list of packages on the Debian Web site to look at the utilities and related programs for both apt-get and dpkg.
FIX BROKEN LINKS IN APT GET INSTALL
If you know that your upgrading habits are risky, it’s also advisable to plan ahead and install packages that can help you when broken dependencies hit. If you still have Web access, you can also check the Debian bug-tracking system to see if anyone else is having the same problem. You can also run apt-get check to check for broken dependencies. The main source, of course, is messages generated by apt-get, which specify exactly what packages are causing problems.

When broken dependencies occur, your first priority should be gathering information. If you’re too impatient to wait, then you have a number of solutions that you can try on your own. Usually, though, information about problems and workarounds can be found via an Internet search, if you can stand waiting for a week or two. In such large upgrades, a few problems are only to be expected. Many users perform system upgrades when a new official version of Debian is released. deb do not yet have a suggested solution, such as holding back a package or removing the conflicting one. Sometimes, a requested package or dependency conflicts with an already installed package, and the scripts included in the. A package may need programs that are not available from the repositories in /etc/apt/sources.list, or a newer version of a program.

Mixing sources from different Debian-derived distributions can also cause problems. However, problems with packages also occur in testing, and even occasionally in stable. Unsurprisingly, they usually happen when using the experimental or unstable repositories, whose contents are still being tested.
FIX BROKEN LINKS IN APT GET UPGRADE
More often, broken dependencies result from attempts to upgrade specific packages or the entire system. Admittedly, converting RPMs with alien or building do-it-yourself Debian packages are possibilities, but these options may require more effort than a casual user would find worthwhile. The trouble is, often the dependencies are unique to the project and the developers never bothered to make Debian packages for them. In this case, the only way out is to patiently track down the dependencies and install them one at a time. That leaves users in the same dependency hell that RPM users had to endure in the bad old days before Yum and apt4rpm.
FIX BROKEN LINKS IN APT GET SOFTWARE
Although more free and open source software (FOSS) projects provide Debian packages than they did five years ago, too often they build them without dependencies calculated. deb packages from a third party, instead of from a Debian-approved source. One case in which you have limited options for recovering the system is when you are installing unofficial. However, as usually happens when an administrative problem arises on GNU/Linux, you have the widest set of options if you open a terminal while logged in as the root user and type the commands directly. Several of these interfaces, in particular Aptitude and dselect, include some of the tools you need for recovering from broken dependencies. The two commands have several interfaces, including Aptitude, Synaptic, KPackage, Gnome-Apt, and dselect. Like apt-get, dpkg is also supported by related utilities, including dpkg-reconfigure and dpkg-deb. Apt-get is supported by a cluster of related utilities, including apt-cache, apt-config, and apt-listchanges.Īpt-get calls on dpkg, the command that actually installs and removes packages. (The repositories may differ for users of some Debian-derived distributions.) CDs and even local directories can also serve as package sources. Normally, for Debian users, apt-get interacts with four online repositories - experimental, unstable, testing, and stable - as listed in each user’s /etc/apt/sources.list file. Package management in Debian-based distributions centers on apt-get, a utility with a high-level set of functions for package management. However, depending on how the broken dependencies arose, you have several options to try before you consider reinstalling. Some users have even been known to reinstall the whole operating system, despairing of otherwise having a functioning package management system. That makes broken dependencies all the more devastating when they happen. They’re a disaster that isn’t supposed to happen in Debian, thanks to the Advanced Packaging Tool (APT) and the scripts contained in Debian packages. Left unresolved, they can cripple your system’s ability to install new packages. These missing packages are known as broken dependencies. When you install an application package in a Debian-based system, sometimes prerequisite application packages are unavailable.
