error when installing libqt0-ruby1.8-qt4 and libqt4-ruby at the same time

Binary package hint: libqt4-ruby

Hi,
something wents wrong with installing the packages libqt0-ruby1.8-qt4 and libqt4-ruby at the same time. libqt0-ruby1.8-qt4 is needed for rbuic to convert QT *.ui files to ruby-rescoure files and libqt4-ruby is needed for using Qt4 inside ruby. But you can't install both from apt-get.

I'm getting these errors when installing:

I can install libqt4-ruby or the other package from apt-get but not both which is needed. Someone knows a workaround for this?

If you would translate:

dpkg: Fehler beim Bearbeiten von /var/cache/apt/archives/libqt0-ruby1.8-qt4_1.4.6-0ubuntu1_i386.deb (--unpack):
Versuche, »/usr/bin/rbqtapi« zu überschreiben, welches auch in Paket libqt4-ruby1.8 ist

to english, I may be able to help.

hi, thats the translation:

dpkg: Error while processing of /var/cache/apt/archives/libqt0-ruby1.8-qt4_1.4.6-0ubuntu1_i386.deb (--unpack):
Try to overwrite »/usr/bin/rbqtapi«, which is also in the packet libqt4-ruby1.8
dpkg-deb: subprocess paste killed with signal (broken pipe)
error happend while processing:

[Scott Kitterman (kitterman)]

This is definitely a bug then.

The work around is to decide which package's version of /usr/bin/rbqtapi you want to keep (it may not matter), install the package that has the one you don't want, then sudo rm /usr/bin/rbqtapi, and install the second. That should work.

What Ubuntu version are you using?

[Adna rim (adnarim)]

I'm using the newest Ubuntu Feisty Fawn

[Adna rim (adnarim)]

Hi thanks for your help but your workaround doesn't work :( I deleted /usr/bin/rbqtapi but the error is exactly the same. But the folder is defenitly deleted!!

[Scott Kitterman (kitterman)]

Sorry about that. I should have time to investigate further in the next
day.

[Adna rim (adnarim)]

Hi,
I found out that the debian packages seemed to have the same problem but fixed it some months ago in libqt4-ruby (1.4.7-3):
http://packages.debian.org/changelogs/pool/main/libq/libqt4-ruby/libqt4-ruby_1.4.9-1/changelog

 * Add diversions of usr/bin/rbqtapi and usr/share/man/man1/rbqtapi.1.gz
     to really remove the conflict with libqt0-ruby1.8
 * Renamed qtrubyinit to qt4rubyinit to avoid conflict with libqt0-ruby1.8

but I still couldn't find any workaround yet..

[Scott Kitterman (kitterman)]

Well you should have that change already since the current Gutsy version is 1.4.7-4. Are you using Ubuntu packages for this?

[Adna rim (adnarim)]

huh sorry I don't exaclty understand what you mean? I'm using the normal Ubuntu Feisty Fawn repos (universe) to install these packages. Here you can watch the repos online:

http://packages.ubuntu.com/feisty/interpreters/libqt4-ruby
---> libqt4-ruby (1.4.6-2)
http://packages.ubuntu.com/feisty/interpreters/libqt0-ruby1.8-qt4
---> libqt0-ruby1.8-qt4 (1.4.6-0ubuntu1)

where should I get this updated version from?

greets

[Scott Kitterman (kitterman)]

Odd. When I looked it up in Launchpad, the Feisty packages don't show:

https://launchpad.net/ubuntu/+source/libqt4-ruby

OK. Well I think I know how to fix this then. Thanks for all the input.

[Scott Kitterman (kitterman)]

Already fixed in Gutsy

[Adna rim (adnarim)]

what does this now exaclty mean? Can I install the gutsy packets on feisty fawn or will the feisty packets be fixed anyway?

[Scott Kitterman (kitterman)]

It means that from a development perspective the bug is fixed as the Gutsy versions have the fixed versions from Debian. From your perspective in Feisty there is a broken package that needs to get fixed. I'm preparing an updated package that will hopefully fix it, but it will take some time to get it tested and published.

[Adna rim (adnarim)]

I would be glad to test it for you, if you updated the package !

[Scott Kitterman (kitterman)]

Well I thought I understood how to fix this one, but I'm not stumped. In addition to working around the actual conflict in qt4-qt-ruby, it's necessary to remove a conflicts in libqt-ruby-qt4 and I can't get that to build without crashing. I do hope someone else takes a stab at this, but I'm afraid it turns out to be beyond me.

[Adna rim (adnarim)]

k thanks nevertheless maybe someone else can handle this

[Adna rim (adnarim)]

still unfixed :(
