Comments.Text: The download attempt might be caused by an attempt to download the files while these files are being updated by the NCBI server. Try downloading on other days and make sure you have a strong connectivity.

  (Asked by: username_0 on 2021-05-26)
  
  I'm trying to download PubMed Central Open Access articles from <ftp://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_bulk>. However, I am not able to decompress the archives without errors.
  
  `tar` always gives me the error:
  
  ```
  gzip: data stream error
  tar: Unexpected EOF in archive
  tar: Error is not recoverable: exiting now
  
  ```
  
  Does PubMed provide corrupted archives or does downloading corrupt the archive?
