[Bioc-devel] Error No internet connection using 'localHub=TRUE' during FlowSorted.CordBloodCombined.450k package installation

[Lucas A. Salas Diaz]

Hi,

One of the users of our FlowSorted.CordBloodCombined.450k package contacted me for advice about an issue during installation using either Bioconductor 3.9 and 3.10. The issue appears when trying to access the ExperimentHub and dealing with a proxy. A similar error was previously reported by Tim Triche and lead to an interesting discussion with the Bioconductor group: https://support.bioconductor.org/p/111958/
However, in this case the problem appears during the .onLoad instead of during the .onAttach. I was not able to reproduce the problem locally. Thus, I believe this is a problem that I should solve for future users.

Do you have any advice on how to solve this problem from the BiocManager::install or from the FlowSorted.CordBloodCombined.450k:::.onLoad? Your advice will be really appreciated.

Lucas

Below a fragment of the issue and potential problematic areas:

The .onLoad here calls to createHubAccessors:

> FlowSorted.CordBloodCombined.450k:::.onLoad
function (libname = find.package("FlowSorted.CordBloodCombined.450k"),
    pkgname = "FlowSorted.CordBloodCombined.450k")
{
    fl <- system.file("extdata", "metadata.csv",
        package = pkgname)
    titles <- read.csv(fl, stringsAsFactors = FALSE)$Title
    createHubAccessors(pkgname, titles)
}

In the meantime they were able to access the database using the following commands:



> library(ExperimentHub)
�
> hub <- ExperimentHub(proxy=Sys.getenv("http_proxy"))
Cannot determine internet connection.
If you experience connection issues consider using 'localHub=TRUE'
