Sounds to me like a problem outside of R (off topic here). In particular, it doesn't sound like you are using the appropriate tools (apt-get package manager for R and a JDK; R install.package() for your R packages) to admin your machine. The only thing you should need sudo for is to run apt-get... everything else should be done as a normal user unless you really know what you are doing. I had no problem installing it just now on my Ubuntu machine with OpenJDK. I have no experience with Mint but Google tells me you should be able to use the instructions for Ubuntu... I would expect Google to tell you the same thing if you ask nicely... your most challenging task at this point should be cleaning up the mess you have made by excessive use of sudo ... most likely running R with it (only update your personal R library directories so you are not tempted to go rogue) but you don't say how you installed the jdk so that could also be messed up.
