A user has reported, and I have confirmed, that r-cran-gert from c2d4u is uninstallable on bionic because it is compiled against a version of libgit2 that is not included with c2d4u:
# apt-get install r-cran-gert The following packages have unmet dependencies: r-cran-gert : Depends: libgit2-27 (>= 0.26.0) but it is not installable E: Unable to correct problems, you have held broken packages. >From the c2d4u buildlog I can see that it is compiling r-cran-gert against the libgit2 backports from ppa:cran/libgit2. So I think the easiest solution is to put a copy of that libgit2 into c2d4u. The same seems to hold for r-cran-v8. The problem does not exist for ubuntu:focal because here the stock versions of libgit2 and libv8 are sufficient and we do not provide ppa backports. _______________________________________________ R-SIG-Debian mailing list R-SIG-Debian@r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-debian
