# Elpa only serves the latest version of a given package uncompressed.
|
|
# Once that release is no longer the latest & greatest it gets archived and compressed
|
|
# meaning that both the URL and the hash changes.
|
|
#
|
|
# To work around this issue we fall back to the URL with the .lz suffix and if that's the
|
|
# one we downloaded we uncompress the file to ensure the hash matches regardless of compression.
