Hello, I tried to install MelonnPan on ubuntu 20.04 subsystem for Windows following the instructions presented in the tutorial ([melonnpan · biobakery/biobakery Wiki · GitHub](https://github.com/biobakery/biobakery/wiki/melonnpan#12-installation)), trying with both R versions 4.1.2 and 3.6.1 in two different conda environments. I had problems as I attempted to install the packages listed: ```auto R -q -e "install.packages(c('devtools', 'glmnet', 'foreach', 'getopt', 'doParallel', 'vegan', 'data.table', 'ggplot2', 'AssocTests', 'optparse', 'tibble'), repos='http://cran.r-project.org')" ``` And in the end I got this error for some of the packages: ERROR: dependency ‘credentials’ is not available for package ‘gert’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/gert’ ERROR: dependency ‘httr’ is not available for package ‘gh’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/gh’ ERROR: dependencies ‘systemfonts’, ‘textshaping’ are not available for package ‘ragg’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/ragg’ ERROR: dependency ‘fExtremes’ is not available for package ‘AssocTests’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/AssocTests’ ERROR: dependencies ‘curl’, ‘gert’, ‘gh’ are not available for package ‘usethis’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/usethis’ ERROR: dependencies ‘httr’, ‘ragg’ are not available for package ‘pkgdown’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/pkgdown’ ERROR: dependencies ‘usethis’, ‘pkgdown’, ‘rcmdcheck’, ‘rversions’, ‘urlchecker’ are not available for package ‘devtools’ - removing ‘/home/studenti/miniconda3/envs/biobakery-melonnpan/lib/R/library/devtools’ The downloaded source packages are in ‘/tmp/Rtmp1XU3Vb/downloaded\_packages’ Updating HTML index of packages in ‘.Library’ Making ‘packages.html’ … done There were 19 warnings (use warnings() to see them) I tried manually installing them in R using install.packages(“_package_”, dependencies=TRUE), but I got the same output. How can I make the dependencies available for the packages I need to run MelonnPan? Thank you ---

Hi @AndreaGatti - you need to install each and every package manually until all the dependencies are installed. In particular, anytime you see that `dependency XXXX is not available for package ‘YYYY’`, you need to manually install `XXXX` before installing `YYYY`. Hope this helps! ---

Thank you, I tried to manually install all the dependencies packages, but got no better result. Nonetheless, I understood that the problem regarded installation paths, so, with a few attempts, I could install everything. Thank you anyway for the quick support!
