Description Leek Soup 2015-08-07 20:23:51 UTC

Description of problem:
I've been trying to get xsane 32-bit to work on my x86_64 hardware. It has always worked in the past for me, but this time with F22, it's severely broken. I've already filed a few bugs in the process.

This time, the problem is I was trying to use rpm with direct http:// link to the 32-bit packages that dnf would not find. It seems that they are not communicating properly, maybe rpm DB is getting out of sync with one or other.


Version-Release number of selected component (if applicable):
dnf.noarch   1.0.1-2.fc22
rpm.x86_64   4.12.0.1-12.fc22


How reproducible:
Happened several times as I was trying to install all packages for xsane.i686 and my scanner.


Steps to Reproduce:
1. sudo dnf install sane-backends-libs.i686
2. rpm -Uvh http://mirror.sfo12.us.leaseweb.net/fedora/linux/releases/22/Everything/i386/os/Packages/s/sane-backends-1.0.24-13.fc22.i686.rpm
3. sudo dnf list sane-backends-libs


Actual results:
1. sudo dnf install sane-backends-libs.i686

Expected results:
If a package is installed it should be recognized as installed by both rpm and dnf. Here clearly dnf installed the sane-backends-libs.i686 package, but rpm did not find it installed.


Additional info:
After this, I tried using rpm to install both sane-backends and sane-backends-libs. At this point, rpm informed me that the libs were already installed ....

	package sane-backends-libs-1.0.24-14.fc22.i686 is already installed

And then, I tried installing the scanner's driver, only to find that rpm had forgotten the sane-backends it had JUST INSTALLED.
$ rpm -Uvh cndrvsane-p150-1.00-0.2.i386.rpm 
error: Failed dependencies:
	sane-backends >= 1.0.14 is needed by cndrvsane-p150-1.00-0.2.i386

Oh, and dnf wouldn't acknowledge it, either:
$ sudo dnf list sane-backends

As you can see from listing above dnf installed sane-backends-libs.i686 1.0.24-14.fc22.
While you tried to install -13.fc22.i686 with rpm (one release older) so rpm reported broken dependencies.
This is correct behaviour and it will work if you install -14.fc22.i686 package with rpm.

Comment 2 Leek Soup 2015-08-10 21:11:53 UTC

Sorry, you are right. I missed that detail. And the reason for the other strange behavior (in Additional info) was that rpm does not install any package if one of them listed is already installed. I thought it was like dnf or yum and would install those that were not installed.

My mistake.
