Travis recently started to fail for Bioc devel (see [0] and [1] for another possibly related report), which seems to related to a warning in BiocManager::available():
BiocManager::version()
[1] ?3.10?
str(BiocManager::available())
Warning: unable to access index for repository https://bioconductor.org/packages/3.10/data/annotation/src/contrib: cannot open URL 'https://bioconductor.org/packages/3.10/data/annotation/src/contrib/PACKAGES' chr [1:16400] "a4" "a4Base" "a4Classif" "a4Core" "a4Preproc" "a4Reporting" ... Is this a temporary or known issue? Thanks in advance. Laurent [0] https://travis-ci.org/lgatto/Features/jobs/538412208 [1] https://travis-ci.community/t/error-bioconductor-version-not-changed/3491
