A user has reported, and I have confirmed, that r-cran-gert from 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.
Jeroen,
In this case, I view this aspect of Launchpad as a feature. Maintaining
c2d4u takes up enough of my time, so if another PPA exists that allows a
package to be built on c2d4u, then I am going to utilize it. Same way I
would encourage anyone wanting to add additional R packages to Launchpad
use my RRutter and c2d4u PPAs as a starting point. No need to reinvent
the wheel.
c2d4u has dependencies on five other PPAs. They are listed on the front
page of the PPA under "Technical details about this PPA" and I strongly
encourage people using c2d4u to install these as well.
