When using package_rpm I didn't get any error even if two packages provided the same file on the target. Package that gets installed later seems to happily overwrite the file (after which both packages own it). With ipk, I get an error as expected: Collected errors: * check_data_file_clashes: Package busybox-syslog wants to install file /home/marquiz/yocto/openembedded-core/build-10433/tmp-glibc/work/qemux86-oe-linux/core-image-minimal/1.0-r0/rootfs/etc/init.d/syslog But that file is already provided by package * sysklogd * opkg_solver_install: Cannot install package packagegroup-core-boot. /build-10433/tmp-glibc/deploy/ipk/i586/eudev_3.2-r0_i586.ipk. 69435 1 dengke.du 2017-01-03 08:51:38 +0000 Hi Markus The following is my steps to reproduce the errors. 1. add IMAGE_INSTALL_append = " busybox-syslog sysklogd" to conf/local.conf 2. add PACKAGE_CLASSES ?= "package_ipk" 3. bitbake core-image-minimal No errors appear, how can I reproduce it? Thanks. 69471 2 markus.lehtonen 2017-01-04 07:48:27 +0000 Oops, I forgot to share the code to reproduce my problem. Please try out git://git.openembedded.org/openembedded-core-contrib marquiz/debug-10694 On branch that you should be able to reproduce the problem with the steps you described. 69741 3 dengke.du 2017-01-12 09:59:12 +0000 Hi Markus The smart can't detect the file clashes, this is an old issue, but the opkg and dpkg can. We will drop the smart package manager, and use the dnf package manager in the future. Thanks. 69750 4 markus.lehtonen 2017-01-12 13:52:53 +0000 But, I think this is a bug in rpm. Rpm should detect that it tries to install a package that would overwrite a file already owned by another package (or tries to simultaneously install two packages providing the same file). 69791 5 dengke.du 2017-01-13 01:41:27 +0000 (In reply to comment #4) > But, I think this is a bug in rpm.

I think detecting the file's owner is the business of package manager. 69793 6 markus.lehtonen 2017-01-13 08:08:33 +0000 And by package manager you mean RPM? It is definitely the job of rpm to keep track (in it's database) about the ownership, checksum etc of files. It is not (only) the responsibility of smartpm, dnf or similar. Packages can be installed with rpm directly, i.e. not using e.g. smartpm, and it needs to detect clashes. 75634 7 mark.hatle 2017-08-03 22:20:26 +0000 The RPM rule is: If both packages provide the -same- file, then it is allowed. On package removal, only the last removal will erase the file. This is the RPM mechanism that allows multiple packages to provide common man pages, configuration files and other components. If you have an example where two packages install -different- contents, and do not error. Then there is an error in RPM, as this should be detected. 75670 8 markus.lehtonen 2017-08-06 16:57:16 +0000 Yes, this was about a common file with _different_ content being provided by two packages. But, it was with rpm5 so I think this could be closed now. 76221 9 dengke.du 2017-08-29 01:19:55 +0000 As Markus mentationed, this bug was with rpm5, so we can close it.
