[SOLVED] Unable to correct bug, you lot take held broken packages

APT is one of the most pop plan in Ubuntu/Debian and their derivatives. It's made to handle the installation and removal of packages. Almost of the time, the application works flawlessly without whatsoever bug. But on rare occasions, you lot may run across "Unable to correct issues, y'all have held broken packages" error bulletin pops up. This error, forth with "apt-become : command not establish" are ii of the almost popular error message when it comes to apt or apt-get in Linux.

This short commodity is going to show yous what crusade the "Unable to correct problems, y'all have held broken packages" error and what you tin can exercise to fix it.

"Unable to right problems, you have held cleaved packages" error

The mistake bulletin may wait something like this :

          Reading parcel lists... Washed Building dependency tree        Reading state information... Washed Some packages could non be installed. This may mean that you have requested an impossible state of affairs or if you are using the unstable distribution that some required packages have not nevertheless been created or been moved out of Incoming. The following data may help to resolve the state of affairs:  The following packages accept unmet dependencies:  ffmpeg : Depends: libavcodec58 (= vii:4.1.six-1~deb10u1)           Depends: libavdevice58 (= 7:4.1.6-1~deb10u1) just 7:4.3.1-6~bpo10+i is to be installed           Depends: libavfilter7 (= vii:4.1.half-dozen-1~deb10u1)           Depends: libavformat58 (= 7:4.1.6-1~deb10u1) just seven:4.3.one-6~bpo10+1 is to be installed           Depends: libavresample4 (= vii:four.1.6-1~deb10u1) only 7:four.iii.1-6~bpo10+1 is to be installed           Depends: libavutil56 (= 7:four.1.vi-1~deb10u1) but 7:4.iii.ane-6~bpo10+1 is to be installed           Depends: libpostproc55 (= 7:iv.1.6-ane~deb10u1) only seven:4.three.ane-6~bpo10+1 is to be installed           Depends: libswresample3 (= 7:4.1.half-dozen-1~deb10u1) only 7:4.3.1-6~bpo10+1 is to be installed           Depends: libswscale5 (= seven:4.1.half dozen-1~deb10u1) but seven:iv.three.1-6~bpo10+ane is to be installed Eastward: Unable to correct bug, y'all take held broken packages.        

Linux systems follow Unix blueprint philosophy : Make each program practise ane thing well. That means a circuitous program has to rely on smaller ones to do its many small jobs.

For example, the VLC media player needs libavcodec, libavutil, libgles2 and a whole agglomeration of other packages to be able to piece of work properly. Those small libraries and software components are chosen dependencies. These dependencies may not be office of the awarding package itself, but they are expected to either be installed on your system already or installed during the installation of the application.

The "Unable to correct problems, you have held broken packages" error usually comes with other information about which libraries/programs needs to exist installed only the system is unable to install them. In the message above, it is python-pip-whl.

The situation may go more complicated when ii programs, let's say VLC and Gnome Video Role player need different versions of the same library. APT, in that example, cannot effigy out how to install both version and raise "Unable to correct problems, you have held broken packages" fault.

Gear up "Unable to correct problems, yous have held cleaved packages" fault

There'due south a few things yous can do to go things to work again. Before following the steps below, make sure you know how to interact with the Linux terminal and the APT command.

Update local parcel alphabetize

If you lot're installing a well-known software, in that location's a high chance that it was tested thoroughly by the original developers also as Ubuntu/Debian team before adding to the parcel directory. In other words, maintainers made sure the software works flawlessly with the organisation, then updating your local package index is a pop way to get rid of the "broken packages" error.

You tin can resynchronize the parcel index files from their sources on Ubuntu via the Internet by running the following command.

          sudo apt update        

Once the update process is done, effort reinstalling the troublesome package again to verify that the error has gone.

Remove left-over packages from your system

Aside from updating package index, removing unused packages from your organization ordinarily helps in case you keep come across "Unable to correct problems, you have held cleaved packages" error.

Every fourth dimension you install a program, its dependencies get installed, likewise. But later you remove the programme, some of the dependencies are left over. Those left-over dependencies rely on other programs, and APT needs to go on track of that information, too. APT has an autoremove command that helps make clean your system from residue packages.

          sudo apt-get autoremove        

Endeavour to search and install the dependency again

If you have tried the two solution in a higher place merely the error message still persist, the dependency may non be available for the distribution version you're running.

Yous can use apt search to look upwards the package index for the troublesome dependency.

          sudo apt search package_name        

If the bundle is available, inspect information technology to see whether information technology'due south the aforementioned version that the arrangement is searching for (specified in the mistake message). And so, attempt to install the dependency package and come across what happens next.

          sudo apt install dependency_package        

At this indicate, y'all may encounter a dependency chain. Basically, the software A depends on B, and so B rely on C, simply C is not bachelor for your distribution version.

It may as well happen that when you try to install package C, information technology is already installed. In that case, check the version of package C. Is it the aforementioned version equally required by bundle B? If yes, then removing C and installing it again could help.

Directly install from DEB file

If the missing dependency cannot exist constitute by apt search, you may effort to install either the parcel or its dependency directly from a DEB file.

For example, in the apt-become output, you can see that ane of the many packages FFMPEG needed is libavcodec58 version 4.1.half dozen-i~deb10u1.

          Reading package lists... Done Building dependency tree        Reading state information... Done Some packages could not be installed. This may mean that you have requested an incommunicable situation or if you are using the unstable distribution that some required packages accept not notwithstanding been created or been moved out of Incoming. The post-obit data may assistance to resolve the situation:  The post-obit packages have unmet dependencies:  ffmpeg : Depends: libavcodec58 (= vii:4.ane.6-1~deb10u1)           Depends: libavdevice58 (= 7:four.i.vi-i~deb10u1) merely seven:4.3.1-6~bpo10+i is to be installed           Depends: libavfilter7 (= 7:4.ane.6-ane~deb10u1)           Depends: libavformat58 (= vii:4.ane.half-dozen-one~deb10u1) simply 7:4.3.1-6~bpo10+1 is to be installed           Depends: libavresample4 (= 7:4.i.six-1~deb10u1) but vii:4.3.1-6~bpo10+1 is to exist installed           Depends: libavutil56 (= vii:four.1.6-1~deb10u1) but 7:iv.3.1-six~bpo10+one is to be installed           Depends: libpostproc55 (= 7:4.1.6-1~deb10u1) merely 7:4.3.1-6~bpo10+1 is to be installed           Depends: libswresample3 (= vii:4.1.6-1~deb10u1) but 7:4.3.1-6~bpo10+i is to be installed           Depends: libswscale5 (= 7:4.i.6-1~deb10u1) but vii:4.three.1-vi~bpo10+ane is to exist installed E: Unable to correct problems, you have held broken packages.        

With this information, you lot can do a quick Google search or a web-based tool like PKGS.org to find the corresponding DEB file. In one case you've downloaded the DEB, install it by running the post-obit command :

          sudo dpkg -i libavcodec58_4.1.vi-1~deb10u1_amd64.deb        

After that, just re-install the troublesome package.

Find another installation source or PPA

If you're trying to install legacy packages, the "Unable to correct issues, y'all have held broken packages" error wold be raised a lot. In this instance, installing individual dependencies can quickly become inconvenient. Your best bet in this state of affairs is to find another installation source, normally a PPA.

Suppose you're trying to install FFMPEG iv, doing a quick search, you would easily find Jonathon F's PPA. You tin can simply add his PPA to your organisation earlier actually re-run apt-go install ffmpeg to install the software.

          sudo add together-apt-repository ppa:jonathonf/ffmpeg-four sudo apt-get update sudo apt-get install ffmpeg        

Alternatively, you lot tin can try to look for the aforementioned software packaged in other formats, such every bit Snap/Flatpak or AppImage.

If yous see the held broken package mistake during update try this

About of the solutions higher up causeless that you see this error while installing a new application. That may not always be the instance.

If you meet this error when you try updating your system with sudo apt update , you may have to accept a slightly unlike approach.

First, bank check which bundle is being held with this command:

          dpkg --become-selections | grep hold        

If yous see any packet held dorsum from updating, you can either remove it (sudo apt-get remove) using or unhold it with the following control

          sudo apt-marking unhold package_name        

The package would be unheld and a confirmation bulletin would exist returned : Canceled agree on package_name..

Conclusion

There is no straightforward gear up for this problem. You'll have to investigate the problem on your own and see if the error can be fixed or not.
