Installation from the Command Line
From the FlexiBee website, download the installation package with the .deb extension.
Flexi can also be installed and uninstalled from the command line. Open a terminal window and install the package using the command sudo gdebi Flexi_2020.3.0.7_all.deb. During the installation, you will be prompted in the same way as when installing via the graphical interface.
On Debian, the gdebi package must be installed separately.
Installation via the Graphical Interface
From the FlexiBee website, download the installation package with the .deb extension and double-click it. A package installation window will appear — click the Install Package button.
The installation will begin. During the process, you will be asked whether you want to install Flexi on a local (standalone) computer only, or whether you want to perform a network installation. Select the installation type and click Next.
If you selected a network installation, you will be asked in the next step whether you want to install the client or the server. The client includes the client application for working with accounting data, while the server provides the data storage (database server) that clients will connect to and where the data for the managed companies will be stored. After making your selection, click Next.
The installation will then proceed. Depending on the speed of your computer, this may take up to several minutes. You will be informed of the installation result in a separate dialog.
Installation Log
If the installation fails, you can find the installation log at /var/log/flexibee-install-log.txt (případně. /var/log/flexibee-client-install-log.txt). If you need to identify the cause of the installation failure, please provide this log to support.
Uninstallation from the Command Line
Flexi can also be uninstalled from the command line. Open a terminal window and uninstall using the command sudo apt-get remove Flexi. During the installation and uninstallation process, you will be prompted in the same way as when installing via the graphical interface.
On Debian, the gdebi package must be installed separately.
Uninstallation via the Graphical Interface
In GNOME, open Synaptic Package Manager from the System – Administration menu. You will first be prompted for the administrator password. After entering it, the manager window will open. Use the Search button to find the flexi package. Select it, then choose Remove from the context menu. Click Apply in the toolbar.
You will then be asked to confirm that you want to remove the package. Click Apply.
During the uninstallation, you will be asked whether you also want to remove the data for the managed companies. Check the option if you want to completely remove Flexi from the system, including all company data. Otherwise, leave the option unchecked and click Next.
You will be informed of the uninstallation result in a final uninstallation dialog.
Package Update
The installed package automatically checks for the availability of a newer version in the same way as other packages in the distribution, and will offer to install it if a newer version is available.
Downloading the Key (Error: Public Key Not Available)
