Apache Config Parsing Errors

I’m using letsencrypt-auto to configure with the Apache plugin. It is having trouble parsing my Apache configuration. Can someone tell me what is wrong here?

Command: ./letsencrypt-auto --agree-dev-preview --server https://acme-v01.api.letsencrypt.org/directory auth --apache

The apache plugin is not working; there may be problems with your existing configuration.
The error was: PluginError((‘There has been an error in parsing the file (%s): %s’, u’/etc/apache2/mods-enabled/alias.conf’, u’Syntax error’),)

/etc/apache2/mods-enabled/alias.conf -> …/mods-available/alias.conf:

# Aliases: Add here as many aliases as you need (with no limit). The format is
# Alias fakename realname
# Note that if you include a trailing / on fakename then the server will
# require it to be present in the URL. So “/icons” isn’t aliased in this
# example, only “/icons/”. If the fakename is slash-terminated, then the
# realname must also be slash terminated, and if the fakename omits the
# trailing slash, the realname must also omit it.
# We include the /icons/ alias for FancyIndexed directory listings. If
# you do not use FancyIndexing, you may comment this out.

Ubuntu Wily, apache2-2.4.12-2ubuntu2.

I am having the same problem on Wily. If I disable a mod file, it just says there is an error in the next one. Perhaps it is an issue with Wily?

Issue seems to also to be related to elements such as <IfModule mod_ssl.c> in conf files. I comment out those lines, it works for that conf file.

I added this as a note in an existing Github issue https://github.com/letsencrypt/letsencrypt/issues/1294#issuecomment-153581276
