[SOLVED]Replace libdbus with core/dbus?

Bednar · 2016-08-28 09:46:16

Hi folks,

Running pacman -Syu today I get the below message:

:: Starting full system upgrade...
:: Replace libdbus with core/dbus? [Y/n]

It looks like libdbus and dbus are in conflict.

What should I do? I don't want to brick the system.

Thanks

I just upgraded, it seems safe.

Upgraded on three systems today. No problems.

Hi.

I just tried to update as usual (sudo pacmatic -Syu). It gave 2 questions:

Recent ML chatter: linux(1)
:: Synchronizing package databases...
core is up to date
extra is up to date
community is up to date
:: Starting full system upgrade...
:: Replace libdbus with core/dbus? [Y/n] n
resolving dependencies...
looking for conflicting packages...
:: dbus and libdbus are in conflict. Remove libdbus? [y/N]

Not knowing what to do, I answered "n" to both, canceling the update.

I did not really understand:
https://git.archlinux.org/svntogit/pack … 9b55087b6c, and I do not know how (or why) to "split" a package.

Would someone please show, step by step, what to do here?

Thanks for your help!

Scimmia · 2016-08-28 15:50:24

Why did you answer no?

Francis Gerund · 2016-08-28 16:06:26

Hi Scimmia,

I replied "n" because I did not really understand the apparent package conflict, and as Bednar said, "I don't want to brick the system."

arojas · 2016-08-28 16:57:45

If you don't understand it, then you should answer yes. That's why it is the default.

Francis Gerund · 2016-08-28 17:13:35

Okay . . . does that mean that I don't have to "unsplit" any packages?

Francis Gerund · 2016-08-28 17:19:36

BTW,

This is the full output of "sudo pacmatic -Syu":

Recent ML chatter: linux(1)
:: Synchronizing package databases...

extra is up to date

No pacnew files to update.

No, this is what has already happened -- the dbus and libdbus packages have merged into one package, so when you install the new dbus package, you need to remove the old libdbus package, that is what pacman is telling you. You just need to agree to the removal.

Francis Gerund · 2016-08-28 17:53:02

Thanks guys (and especially WorMzy, for the explanation).

I did the update, choosing "y" at ":: Replace libdbus with core/dbus? [Y/n]"
It seemed to go fine.

I appreciate the help.

I think that could be a bit dangerous. You don't think it's better to do some research before agreeing to make system changes which you don't understand? If you select (N), you can always come right back and do it again after checking to see what it's wanting you to agree to.

danidee · 2016-08-28 18:57:28

Just checking in....does anyone have any explanation (i also don't want to brick my system). Moreover i want to know why libdus isn't compatible and has to be replace. google hasn't been of much help

The dbus update kills X on mine. I've posted bug reports upstream and on flyspray. Just saying.

Agreed. Blindly selecting 'Y" on things you don't understand is HORRIBLE advice.

Agreed. Blindly selecting 'Y" on things, just because it is the default, is HORRIBLE advice.

Horrible advice provided by the pacman devs...

There is a default for a reason. No-one is suggesting that you blindly do anything in Arch, but if you read pacman's output and it looks reasonable, then accept the default.

nobloat · 2016-08-28 20:10:53

Was there no way to give a more helpful information in pacman , i.e. to tell why there is a replacement of libdbus with core/dbus?

Something like

:: Starting full system upgrade...
:: Replace libdbus with core/dbus? (info: libdbus was moved into the core/dbus package) [Y/n]

Not being too familiar with all package names I was first imagening that userspace dbus was somewhat replaced by a kdbus, so there was some shock moment here.

If it told directly that it is simply a change in packages (or any reason/info) it would have been helpful.

I agree that the default option is going to be right nearly all of the time. However, there's no negative consequence to telling pacman to halt so you can figure out what it wants you to do first. I still think this would be better than just assuming the default options will always be alright.

jasonwryan · 2016-08-28 20:45:37

I was responding to more of the histrionic tone in the thread. Arch is for competent users, not people that panic and want their hand held whenever something changes in a rolling release distro.

To reiterate, if you are offered a choice by pacman, accept the default: it is what the devs recommend.

If you want to understand why; read the changelog for the package, look at the ML, upstream, or ask here for clarification.

Of course. I just think it's always a good idea to advocate understanding and good practices. Safety first and all.

The replaces field in pacman does not have a way of specifying the reason why one package should replace another.

If you want it to be able to do so, open a bugreport against pacman, and ask for it as a feature request.

ksolsim · 2016-08-28 22:07:06

I get this instead:

[root@arch ksolsim]# LC_ALL=C pacman -Syu

:: Starting full system upgrade...

:: lib32-dbus-core: installing dbus (1.10.10-3) breaks dependency 'dbus-core'

WorMzy · 2016-08-28 22:15:45

lib32-dbus-core was replaced by lib32-libdbus some time ago*. If you're going to install from multilib, then disable the multilib repository, then you're going to be doing partial updates.

* over two years ago: https://git.archlinux.org/svntogit/comm … 06d854a2e0
