Hi I have installed BiocManager,
if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager")
but when I load this package,
library(BiocManager)
it occurs the following error:
Bioconductor version cannot be validated; no internet connection?
Warning message:
In file(con, "r") :

Hi Sveda, If you are still having this issue, there are a few scenarios where you might get this error. For example,
Network Connectivity Issues:
Firewall or Proxy: Your network or system firewall/proxy settings might be blocking access to external repositories. Check your firewall settings and ensure that R and R packages are allowed to connect to the internet. Proxy Configuration: If you are behind a corporate network, you may need to configure proxy settings within R to allow access to external resources.
SSL/TLS Configuration:
The "SSL connect error" suggests there might be an issue with the SSL/TLS configuration. Ensure that your R installation has the necessary SSL libraries and certificates.
Best regards, Marcel
Hello, I can install packages using install.packages(), which requires an internet connection. However, even with BiocManager, this issue still occurs. thank you for your guide.
Hi Sevda,
The issue is most likely due to your internet configuration. Please make sure that your ISP or work internet is not blocking access to bioconductor.org. See this issue posted at BiocManager #183 for more information.
Best,
Marcel
