LedgerSL for Linux - Installation and First Connection Package version: 2026.10.04-1 Release date: October 4, 2026 REQUIREMENTS Linux Mint 22.x or Ubuntu 24.04 desktop, 64-bit Intel/AMD (amd64/x86-64). Lazarus and Free Pascal are not required. This package is not for ARM, Windows, or macOS. SQLite uses a local database file; no database server, server address, port, or separate database password is needed. 1. INSTALL Download ledgersl_2026.10.04-1_amd64.deb from www.ledgersl.com. On Linux Mint, double-click the downloaded file and use Package Installer. Alternatively, open a terminal in the folder containing the .deb and run: sudo apt install ./ledgersl_2026.10.04-1_amd64.deb APT installs any missing runtime libraries from your configured repositories. An Internet connection is needed if dependencies must be downloaded. 2. START LEDGERSL Open LedgerSL from the application menu, or run: ledgersl Run the application as your normal desktop user, without sudo. The first launch creates your writable application and database folders automatically. 3. CONNECT TO THE SAMPLE COMPANY THE FIRST TIME At "LedgerSL First Start", choose "Open Demo Company". This connects to the included SQLite database; no server setup is required. If you need to select it manually, choose "Browse for Database..." and open: ~/.local/share/LedgerSL/data/LedgerSL_Demo.db The ~ means your own home folder. In the file chooser, Ctrl+H shows hidden folders such as .local. Open .local, share, LedgerSL, then data, and select LedgerSL_Demo.db. Select your writable home-folder copy, not the system package under /usr/lib/ledgersl. If a company is already remembered, LedgerSL may open it directly. Use Company > Change Company > Open Demo Company when you want the sample. Follow the restart prompt after changing companies. The selected database is remembered for later launches. 4. SET YOUR SAMPLE-COMPANY PASSWORD AND LOG IN For a fresh installation, the sample has the administrator user name Demo. When prompted to initialize its password, choose and confirm your own password of at least 8 characters. The prompt may say "Application security has been upgraded." This is expected for the new sample copy. At Accounting Login, enter: User name: Demo Password: the password you just chose There is no shared default password. An update keeps the login and password already stored in your existing database; it does not reset them. Choose your accounting date after login. To review the complete sample year, use December 31, 2026, and January 1 through December 31, 2026 for reports. All sample transactions are fictional, including dates later than this release date. Select all divisions when reviewing the whole company. 5. CREATE YOUR OWN COMPANY Keep practice transactions in the sample database. Sign in as an administrator and choose Company > Change Company > Create New Company. Enter a recognizable name such as AcmeSupply.db and choose a local folder you can write to. Follow the restart prompt. Create your administrator user and password when the new company requests them, then sign in. Choose Company > Company Setup Wizard to enter your company information. At Step 4: GL Accounts, load the starter chart into the empty chart or import your own CSV. Review and confirm the accounts, then configure posting accounts and the remaining company settings before entering live business. LedgerSL_Empty.db is the reusable template; do not open it directly or use it as your working company file. TO CONNECT AN EXISTING COMPANY Choose Browse for Database... and select its .db file in a writable local folder. Use that company's existing application login. Check the company name and full database path before entering transactions. One person should use a company database at a time; use local storage rather than a network share or an actively synchronized cloud folder. UPDATES AND BACKUPS Close LedgerSL before installing an update. Install the newer .deb in the same way. Existing databases, passwords, grid preferences, and saved company selection are preserved. A new sample database is supplied only when the user does not already have that file; updates do not replace existing data. For an older ZIP installation, run "ledgersl" once from a terminal after installing this .deb to update its managed launcher. Before updates or important changes, use Company > Back Up Company to save a dated copy on a separate drive or other protected location. Finish and save transaction edits before backing up. The Source Backup tool is for programming files, not your company database. IF THE DATABASE DOES NOT OPEN - Choose Browse for Database... and check the full path above. - Use the database copy in your own home folder and ensure it is writable. - Close another LedgerSL instance if the file is already in use. - If the application reports an incompatible schema, use a matching LedgerSL version or contact support; do not rename an unrelated SQLite database. - For a runtime/dependency check, run: ledgersl --check - Help > Support Information shows the database/settings locations and diagnostic details. Review that information before sending it to support.
