Attachments:	install.log from upgrade of Mandriva 2010.2 + backports i686 system

Description Dave Hodgins 2011-04-01 04:25:09 CEST

I tried using a dvd install to upgrade an existing 2010.2 Mandriva installation
using the alpha2 iso.

During the install, 75 packages failed to install, due to the Mandriva install having
many devel packages installed, where the mageia install iso doesn't have the devel
packages.

urpmi blocks the install of the package, when the package it's replacing is marked as required by the devel package.  In my opinion, devel packages shouldn't require the non-devel packages, but they do.

I think that the installer has to detect this condition, and either automatically remove the devel packages, or use the --nodeps option, or prompt the user as to
which option should be used.

After the install, without those 75 packages, drakrpm-edit-media still picked up Mandriva mirrors when adding complete media list.

Reproducible:

Created attachment 185 [details]
install.log from upgrade of Mandriva 2010.2 + backports i686 system

Looking through the install log, there are a lot more conflicts than just
the devel conflicts I noticed on the screen, during the install.

Comment 3 Dave Hodgins 2011-04-02 02:41:01 CEST

After reviewing the install.log, I restored the Mandriva system, and then
uninstalled perl-Digest-SHA-PurePerl, and ran the install/upgrade again.

No installation transactions failed, so all of the problems were due to the
first installation transaction failing, due to
file /usr/bin/shasum from install of perl-Digest-SHA-5.610.0-1.mga1.i586 conflicts with file from package perl-Digest-SHA-PurePerl-5.480.0-1mdv2010.1.noarch

Comment 4 Ahmad Samir 2011-04-02 05:18:13 CEST

This is the infamous urpmi-cascading-failure bug, it fails to upgrade one package, and the whole transaction fails (transactions are split in 8-package groups).

Comment 5 Jerome Quelin 2011-04-02 10:43:02 CEST

this has been fixed in new packages, with pure-perl /usr/bin/shasum renamed to /usr/bin/shasum.pl

however, urpmi doesn't upgrade perl-Digest-SHA and perl-Digest-SHA-PurePerl in the same transactions, creating a file conflict...

this is more a urpmi bug i'd say. unless there's a way to mark 2 packages to be upgraded in the same transaction.

Comment 6 Thierry Vignaud 2011-04-04 11:26:55 CEST

No this is not an urpmi bug but a packaging issue.

In order for urpmi to put these packages in the same transaction, you've to provide hints to it.
urpmi cannot devine for you.

It's well documented that in such case, you've to make _both_ packages conflicts with the previous version of the another one.
That will force urpmi to put these two packages in the same transaction.

Comment 7 Jerome Quelin 2011-04-04 13:03:18 CEST

sorry, but i wasn't aware of that. so, what should i add in spec file?

in perl-Digest-SHA.spec:
(assuming we have %mkrel 2)
Conflicts:  perl-Digest-SHA-PurePerl <= 5.610.0-1.mga

in perl-Digest-SHA-PurePerl.spec:
(assuming we have %mkrel 2)
Conflicts:  perl-Digest-SHA <= 5.610.0-1.mga

but this doesn't work when trying to install the resulting rpm: it should be conflicting, yet it installs fine.

Comment 8 Thierry Vignaud 2011-04-04 14:11:16 CEST

You need to put "Conflicts: perl-foobar < working_version-working_release"
(plus epoch if hose packages use one)

Comment 9 Jerome Quelin 2011-04-04 14:27:41 CEST

thanks - fixed in 5.610.0-2.mga1

Status: NEW => RESOLVED
Resolution: (none) => FIXED

Without the logs (/root/drakx/report.bug.gz), no one can say.

Comment 13 Marcello Anni 2011-04-21 10:52:16 CEST

thank you
