Important: The Linux download provided here is a .deb package for 64-bit Intel/AMD (amd64/x86-64) Linux systems. It is intended primarily for Debian-based distributions such as Ubuntu, Linux Mint, Debian and other distributions that support .deb packages and the apt package manager.
Step 1: Download the LagnaOne .deb package.
Click the CLICK HERE TO DOWNLOAD .deb button above and save the file to your computer. The downloaded filename should be:
lagna-one_2.5.2_amd64.deb
Step 2: Open Terminal and go to the Downloads folder.
In most Linux installations, downloaded files are stored in the Downloads folder. Open Terminal and run:
cd ~/Downloads
If your browser saved the file somewhere else, navigate to that folder instead. You can also type cd followed by the folder location.
Step 3: Install LagnaOne using apt (recommended).
The recommended installation method is to use apt. Run:
sudo apt install ./lagna-one_2.5.2_amd64.deb
Linux will ask for your user password because installing software requires administrator privileges. When you type the password in Terminal, nothing may appear on the screen while you type. This is normal. Type the password and press Enter.
The apt method is recommended because it can automatically handle required package dependencies where they are available through your Linux distribution's package repositories.
Step 4: Complete the installation.
If Terminal asks you to confirm the installation, type Y and press Enter. Wait until the installation process finishes and the Terminal prompt returns.
Step 5: Launch LagnaOne.
After successful installation, you can normally launch LagnaOne from your Linux Applications menu / application launcher. Look for LagnaOne in the list of installed applications.
You normally do not need to open Terminal every time you want to use LagnaOne.
If you have difficulty installing the .deb package:
A) If apt reports missing or broken dependencies:
Run:
sudo apt --fix-broken install
After that completes, try installing the LagnaOne package again:
sudo apt install ./lagna-one_2.5.2_amd64.deb
B) Alternative installation using dpkg:
If you prefer, or if your Linux distribution does not handle the package through the above command, you can install the .deb using:
sudo dpkg -i lagna-one_2.5.2_amd64.deb
If dpkg reports dependency problems, run:
sudo apt --fix-broken install
Then, if required, run the installation command again:
sudo apt install ./lagna-one_2.5.2_amd64.deb
If LagnaOne does not appear in the Applications menu:
First make sure that the installation completed without errors. You can try logging out and logging in again, or restarting your Linux desktop session.
You can also check whether the package was installed by running:
dpkg -l | grep lagna-one
If LagnaOne does not start:
If clicking the LagnaOne icon does nothing, open Terminal and try launching the application from there. This can display an error message that may help identify the problem.
The exact launch command can vary depending on the package installation and Linux distribution. If LagnaOne is available as a desktop application but does not start from the Applications menu, please report the problem through the LagnaOne issue tracker and include the Linux distribution and version you are using, along with any error message displayed by Terminal.
Please note: LagnaOne is distributed here as a standard .deb package. You do not need to install LagnaOne from Ubuntu Software, Snap Store, Flathub, or any other Linux software store.
FUSE is also not required for the .deb installation. FUSE is generally associated with other Linux package formats such as AppImage and is not required simply to install LagnaOne using the .deb package provided here.
About LagnaOne's files and data:
LagnaOne creates and uses its own application data folder for its files and settings. Normal operation does not require you to manually create special folders or change permissions for unrelated files on your Linux system.
You should normally install and run LagnaOne using your regular Linux user account. The sudo command is required for installation because installing a system application requires administrator privileges; it is not normally required every time you launch LagnaOne.
Uninstalling LagnaOne:
If you ever want to remove LagnaOne from your Linux system, you can normally uninstall it using:
sudo apt remove lagna-one
If you also want to remove system package configuration files associated with the package, you may use:
sudo apt purge lagna-one
Note: Removing the application package does not necessarily mean that personal application data or files created separately by the application are automatically removed. If you need to completely remove such data, check the LagnaOne application-data folder separately before deleting anything.
Important compatibility note:
The download provided above is specifically for amd64 (64-bit Intel/AMD) Linux systems. If you are using an ARM-based Linux computer, such as certain Raspberry Pi or ARM-based laptops, this particular package is not the appropriate package for your system.
If you are unsure which architecture your Linux computer uses, open Terminal and run:
uname -m
For a typical 64-bit Intel/AMD Linux computer, the result will be:
x86_64
If you encounter any installation or execution problem, please report the Linux distribution name, Linux version, computer architecture, and the exact error message through the LagnaOne issue tracker. This information will help diagnose the problem.
