Deleting dependencies

pennsatucky · Jan 3, 2015

Hi friends.
So I have a very common question..how to remove package and all dependencies?
FreeBSD 10.1

I've tried pkg autoremove after deleting some port, but it is going to delete many packages. For example, I've removed icewm, autoremove wants to delete bash, zim etc. So I just "locked" them.

And now I'm frustrated...
So can someone tell me, how I should properly delete dependencies without my system getting broken?

pkg autoremove is the correct way to go about this. Any packages that were automatically installed and no longer needed will get removed. For whatever reason, some packages you rely on look to be marked as automatically installed. You may want to review the lists and set the packages you want to be non-automatic so pkg autoremove won't touch them.

List non-automatic, explicitly installed, packages:
pkg query -e '%a=0' %o

List automatic packages:
pkg query -e '%a=1' %o

Set a package to be non-automatic:
pkg set -A 0 bash

See pkg help query and pkg help set.

I wish to know if the command portmaster -s is a good solution for clean dependencies...
Seem nobody have mentioned this way in the forum.

Just use the native tool for the job. portmaster(8) just calls pkg(8) anyway so just use pkg autoremove to remove unused dependencies.

I not knew about pkg autoremove. Thanks for the reply!

Hello everybody,

I have a question regarding the works of pkg autoremove:
Once I install a package it wants to delete the dependencies needed for installation. Here is an example:

 

# pkg install ninja

New packages to be INSTALLED:

        ninja: 1.8.2,2 [FreeBSD]

        compat10x-amd64: 10.3.1003000.20170608 [Synth]

        svgalib: 1.4.3_7 [FreeBSD]

        lapack: 3.5.0_5 [FreeBSD]

        blas: 3.5.0_4 [FreeBSD]



Number of packages to be installed: 5



The process will require 40 MiB more space.



Proceed with this action? [y/N]: y

[1/5] Installing blas-3.5.0_4...

[1/5] Extracting blas-3.5.0_4: 100%

[2/5] Installing ninja-1.8.2,2...

[2/5] Extracting ninja-1.8.2,2: 100%

[3/5] Installing compat10x-amd64-10.3.1003000.20170608...

[3/5] Extracting compat10x-amd64-10.3.1003000.20170608: 100%

[4/5] Installing svgalib-1.4.3_7...

[4/5] Extracting svgalib-1.4.3_7: 100%

[5/5] Installing lapack-3.5.0_5...

[5/5] Extracting lapack-3.5.0_5: 100%

and now:

 

# pkg autoremove



Checking integrity... done (0 conflicting)

Deinstallation has been requested for the following 4 packages:



Installed packages to be REMOVED:

        lapack-3.5.0_5

        blas-3.5.0_4

        compat10x-amd64-10.3.1003000.20170608

        svgalib-1.4.3_7



Number of packages to be removed: 4



The operation will free 40 MiB.



Proceed with deinstalling packages? [y/N]:

aren't those packages dependencies for ninja?

None of them are dependencies of devel/ninja:

Code:

root@molly:/usr/ports/devel/ninja # make {run,lib}-depends
===>   ninja-1.8.2,2 depends on file: /usr/local/bin/python2.7 - found

There's also a irc/ninja but it has 0 (zero) dependencies:

Code:

root@molly:/usr/ports/irc/ninja # make {run,lib}-depends
root@molly:/usr/ports/irc/ninja #

Both end up having a package named ninja. But judging by the version, you're dealing with devel/ninja.

KoMa350 · Oct 17, 2018

thanks for your quick reply. indeed devel/ninja, sorry for not having clarified.

haven't thought about checking it out this way, actually pkg itself shows the same:

 

# pkg info -d devel/ninja



ninja-1.8.2,2:

python27-2.7.15

so something fishy is going on when installing devel/ninja with pkg, for some reason it installs 4 ports that don't seem to be necessary. well, i won't think about it too much, pkg autoremove works seemingly alright, and that was the issue in the first place.

thanks again for your help, cheers!

I couldn't help notice mention of Synth in your first post, are you perhaps installing both ports and binary packages at the same time? Because that could definitely explain a thing or two, and it's usually not the best of ideas because it can cause dependency conflicts.

KoMa350 · Oct 20, 2018

well, here's how i approach ports/packages:
for a new install i normally use pkg, except when there's a config i want to change, e.g. with multimedia/ffmpeg. then i'd build from ports. i use Synth for updating the installed ports/packages, and in the mentioned case compat10x-amd64 was found in the synth repository, i guess.
so probably yes, i'm mixing ports and packages...
