[R-sig-Debian] Problem when installing lme4 under Debian stretch

[Johannes Ranke]

Hi,

apparently you are using the backport of R 3.4.2, which provides r-api-3.4.
With this backport installed, you cannot use the binary packages from the 
stretch archive.

You should still be able to install car from within R, which you tried. On my 
raspi system using the unofficial Debian stretch image from 

  https://wiki.debian.org/RaspberryPi3

I had to install ed (apt install ed) in order to get the dependency nloptr to 
compile. Now the compilation of the dependency RcppEigen is running (which 
seems to have failed or was interrupted on your system, judging by the error 
message you posted). Surely more than five minutes ago my raspi started to 
compile the file fastLm.cpp ...

I will let you know if I succeed. But Dirk is right when he points out that 
the efficiency of using such a system to compile lots of source packages is 
questionable. Maybe it would be a solution to deinstall the backport, remove 
the stretch-cran34 line from your sources.list and install everything from the 
stretch archive. R version 3.3.3 from stretch is still sort of recent...
