Refusing to serve hidden directory, via 404 Error

I got this error while running jupyter notebook inside my EC2

My Solution --> when i first run it, i was inside .jupyter directory.

Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_main_binary-amd64_Packages

I am using Ubuntu 12.04 LTS 64bit , Must say that i am having a lot of error issues.

Got this error above when i tried to update.

This solved that :

sudo rm -vf /var/lib/apt/lists/*

Group not found: launchGroup

Happened to me in eclipse, unable to compile my project although it's not the issue.
I have found that in the work space directory there is a file named ".lock" in which eclipse creates.
After exiting Eclipse -> Deleting this file -> Entering again to eclipse -> Trying to compile the project succeeded.


See ya,

org.postgresql.util.PSQLException: ERROR: syntax error at or near

This happen when you have a name which is a reserved name or already exists by a table for example.

Lets say your are trying to add a new table and the error was:
org.postgresql.util.PSQLException: ERROR: syntax error at or near "User"

You got this error since the postgresql in the current schema has already a User table and this name is reserved.
Change your table (if in your case like this example, it's a table issue) name to a different.
