As of a few days I'm seeing this error on travis: The following packages have unmet dependencies: libleptonica-dev : Depends: liblept5 (= 1.74.4-1+nmu1ppa1~trusty1) but it is not going to be installed Which is caused by: The following packages have unmet dependencies: liblept5 : Depends: libopenjp2-7 (>= 2.0.0) but it is not installable This is caused by the recent update libleptonica on c2d4u. I guess this new version also requires a backport of libopenjp2-7. More generally I'm wondering if perhaps c/c++ libs backports should go into a separate PPA? I was assuming c2d4u would only provide r-cran packages but not have any side effects on system libs.
broken dependencies on 2cd4u

Jeroen, Sorry about this one. There was an update of the tesseract package, and it required a newer version of libleptonica-dev. I thought I could copy in a version from another PPA and have it work cleanly, but this was not the case. I have deleted both packages, thus putting things back to the way they where as of January 26th. Let me know if there are still issues. Michael

OK thanks for fixing it :-) I think it would be useful having a separate PPA where we provide backports of important libs used by R packages. But these should not be in c2d4u, because then enabling c2d4u may have unexpected side effects on non-R software. I maintain backports of imagemagick and jq myself (for the magick and jqr packages). We could add one for tesseract 4 as well, once it is final: https://launchpad.net/~opencpu/+archive/ubuntu/imagemagick https://launchpad.net/~opencpu/+archive/ubuntu/jq J
