NebulaGraph Database Version: 3.1.0
Failed to open connection, error: incompatible version between client and server: Graph client version(2.6.0) is not accepted, current graph client white list: 3.0.03.1.0…

Looks like your NebulaGraph Studio version is not compatible with the NebulaGraph database version.
Upgrade your NebulaGraph Studio to solve this issue. For the valid version, see NebulaGraph Studio docs.

Python only mysql.connector replacement with compatible api for mariaDB

I'm trying out this command, but it fails miserably:
python: MariaDB Connector/Python requires MariaDB Connector/C >= 3.1.3, found version 3.0.3 on ubuntu 18.04
Complete output from command python setup.py egg_info:
MariaDB Connector/Python requires MariaDB Connector/C >= 3.1.3, found version 3.0.3
is there a non c version of mysql.connector compatible with the latest mariadb?
the problem was I was connecting to one db with a user which was not authorized to do the thing on the other db. the error message did not include the DB name.
double check the db name is correct on the query itself.

Where can I download previous / older versions of Flyway?

We are currently running version 4.0.3 and can't go to the latest as support for our database has been dropped (SQL Server 2012). I would like to get the latest version 4 release (4.2.0) - can anyone tell me if this is possible and if so, where can I find it?
Apparently the source code for all previous versions is in GitHub. Now the question becomes "Is there anywhere I can find the Windows executable version of Flyway 4.2.0?"...
You will probably have to build the executable from source using one of the releases on their Github. 4.2.0 is available here
The various binaries, as well as the source, for 4.2.0 can be downloaded from Maven Central.
Here is the 4.2.0 Windows zip.

Install Aptana Studio on windows

When I try to install Aptana Studio, I get an error message Failed to correctly acquire installer_nodejs_windows.msi file: CRC error. I am then told that Aptana Studio setup ended prematurely bacause of an error. The installer then shuts down without installing the application. I have installed nodejs, but still get this error.
This is because the PC you are installing it on, has no internet connection.
I had following message boxes before I got the error you mentioned:
Solution: On a PC connected to internet either go to the URLs above , download and transfer the installer files to your PC, or get the newest versions of nodejs and git, then install them on your development PC.

I get the same error when trying to install Aptana 3.6.1 just now. Found the solution in this thread another thread(run the installer with "/passive /norestart").

Uninstall teradata ulitilies issue

I am trying to install teradata utilities 15.x,
I earlier installed teradata ODBC drive and .NET Data Provider for teradata.
Now if I start the installation, I get an error saying:
"The installation failed for the following reason:
A TTU 14.0 suite is installed. Please uninstall all TTU 14.10 suites before installing TTU 15.00"
I tried to uninstall the suite using uninstall_TTU.vbs, but I get below error:
TTUSuiteSilent.exe was not found in .\TTU directory.
This script needs TTUSuiteSilent.exe to remove suite packages.
Aborting uninstallation....
Any advise on how to get this uninstalled?
The Teradata ODBC driver typically requires three components to be installed on the client:
ICU Libraries
GSS Libraries
ODBC Driver
You must ensure that all three of these have been removed before you can replace them with another version. Typically, they can be found in the Add/Remove Programs applet of the Windows Control Panel.
