Hello Christopher,
Sorry if my initial email was not clear enough.
I have an Accumulo datastore connected with my Geoserver. I figured the problem
because Geoserver had an issue connecting to the datastore.After figuring out
that there is a problem with Accumulo I noticed that the datastore has a
problem, through different verification methods.
I cannot access the tables even when using the shell or the monitor interface.
Every time I try to access any information I get the connection refused error
in the logs.
I mentioned the certbot update as it led me to unistall and install Apache2,
based on the link that you provided I am afraid that I have install a different
version that it is causing the issue.
Is there a way to verify that I have a compatible version and/or install the
proper one?
If there is additional information that I can provide to further clarify the
issue please let me know.
Best regards, Maria.

Hi Maria,
I'm not sure this is an Accumulo issue. Accumulo doesn't have a
"Geoserver" service, and should not be affected by anything related to
certbot. This might be a Geomesa-specific issue, which is not a
project maintained by the Accumulo developers (though, there may be
knowledgeable people on list who can help you).
The one issue that indicates it might be related to Accumulo is the
stack trace with vfs2 stuff. Accumulo does have vfs2 as a dependency,
and I think I may have seen some similar stack traces with certain
versions of commons-vfs2
(https://github.com/apache/accumulo/issues/933) but it's hard to tell
from what you have provided, since there's no Accumulo code mentioned
in the stack trace.
