Hello,

I updated my Ubuntu installation to 18.04 (support for 17.10 expired), and now I can no longer load Ballgown in R.

I get the following error:

con@con-VirtualBox:~/RNASeqb/Milanovich/genomeNext/compare$ Rscript pathfinder.ballgown.R
Loading required package: methods
Error: package or namespace load failed for ‘ballgown’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/usr/local/lib/R/site-library/RCurl/libs/RCurl.so':
  /usr/lib/x86_64-linux-gnu/libcurl.so.4: version `CURL_OPENSSL_3' not found (required by /usr/local/lib/R/site-library/RCurl/libs/RCurl.so)
Execution halted

simply removing curl and reinstalling still produces the same error (https://community.rstudio.com/t/error-version-curl-openssl-3-not-found/8090)

How can I get ballgown working?
