I am working on upgrading an embedded target from Qt 5.9.3 to 5.12.10. Most packages work OK, however the qtvirtualkeyboard package is causing issues. The build process (using Yocto/bitbake) creates an upgrade package, which contains all the generated RPMs for all packages and on the target we use the Smart Package Manager to install these.
This works OK for almost all packages, only the qtvirtualkeyboard package has a different name in the new build: the RPMs changed from qtvirtualkeyboard (in Qt 5.9.3) to libqt5virtualkeyboard (in Qt 5.12.10). It looks like this confuses the package manager and it exits with an error indicating that certain files cannot be overwritten, as they are part of an already installed package. This is one of the messages, the others follow the same pattern, all about qtvirtualkeyboard-qmlplugins:
error: file /usr/lib/qt5/qml/QtQuick/VirtualKeyboard/plugins.qmltypes from install of libqt5virtualkeyboard-qmlplugins-5.12.10.3+git0+1582869a39-r0.cortexa9hf_vfp_neon conflicts with file from package qtvirtualkeyboard-qmlplugins-5.9.3+git3+81f9e4b142-r3.0.cortexa9hf_vfp_neon
There are a number of other packages that are generated as libqt5name package instead of a qtname package, but these already had this name in 5.9.3, so they are not causing an issue.
In the ..../pkgdata/runtime/qtvirtualkeyboard-qmlplugins there is a line:
PKG_qtvirtualkeyboard-qmlplugins: libqt5virtualkeyboard-qmlplugins
Which was (in Qt 5.9.3):
PKG_qtvirtualkeyboard-qmlplugins: qtvirtualkeyboard-qmlplugins
To me it looks like the package is receiving a new name.
I tried adding an RREPLACES_${PN} and RCONFLICTS_${PN} with "qtvirtualkeyboard (< 5.12.10)" to a qtvirtualkeyboard_git.bbappend file, but that did not help. There is an Obsoletes line added in the SPECS file (reading back from the generated RPM using rpmrebuild), but that also referenced the new name, libqt5virtualkeyboard.
Is it possible to revert this change of the name (for my local build) or can I add a rule somewhere that makes sure the package manager removes the original package before installing the new package?
I am using meta-qt5 (hash 8da88b09, which is the last 5.12.10 version) and the official Qt GIT repo for 5.12.10.
After diving into the buildroot/poky code I found out that the rename is done when an RPM only contains libraries. The original RPM did contain only some support files (so it was not renamed), but the new RPM contains only libs.
I solved this by adding the following line to my qtvirtualkeyboard.bbappend:
Now the name is not changed anymore and the upgrade is working as expected.
