Description of problem: It is not possible to install the R-preprocessCore package on an x86_64 Fedora 28 system, as it is linked against libgfortran.so.4, which no package provides (the current version of libgfortran.so is .5). Looks like the package was not rebuilt for Fedora 28 and instead the (non-functional) Fedora 27 package is provided. Version-Release number of selected component (if applicable): R-preprocessCore-1.38.1-3.fc27.x86_64 How reproducible: Always Steps to Reproduce: 1. dnf install R-preprocessCore Actual results: dnf fails with the following output: Error: Problem: conflicting requests - nothing provides libgfortran.so.4 needed by R-preprocessCore-1.38.1-3.fc27.i686 - nothing provides libgfortran.so.4()(64bit) needed by R-preprocessCore-1.38.1-3.fc27.x86_64 Expected results: Package is installed successfully.
Looks like this was caused by bug #1555561, FTBFS for F28. However, I just took the SRPM from F27 (R-preprocessCore-1.38.1-3.fc27.src.rpm) and rebuilt it in an F28 mock environment and it built just fine (making R-preprocessCore-1.38.1-3.fc28.x86_64.rpm, which installs with no issues). So perhaps this was just a transient Koji failure, and poking it again should trivially fix this?
This seems to be a more general problem, several more R packages have the same problem: R-lmtest-0.9.35-3.fc27.x86_64 R-maanova-1.46.1-3.fc27.x86_64 R-msm-1.6.4-3.fc27.x86_64 R-shogun-6.0.0-5.fc27.x86_64 R-statmod-1.4.20-7.fc27.x86_64 R-waveslim-1.7.5-6.fc27.x86_64 R-mvtnorm-1.0.6-3.fc27.x86_64 plus there are packages that depend on the those listed and which can't be installed. One can easily reproduce this with something line 'dnf install R-*'. Was there a repo closure run before releasing F28???
And seemingly there is a related bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1575940
We now have R-preprocessCore 1.42.0 which I believe fix this issue. If it does not, please re-open this ticket.
