If during setting up of SqlBak on Linux or during a backup job one of the following errors occurs:

PostgreSQL DBMS – /bin/sh: 1: /usr/bin/psql: not found
or
PostgreSQL DBMS – /bin/sh: 1: /usr/bin/pgdump: not found

it means that SqlBak app could not find the path to postgresql executables. By default, SqlBak looks for postgresql files in the /usr/bin/psql directory. 

How to fix the issue

To resolve the issue please follow these steps:

1. Make sure that postgresql-client is installed

   To do this, please execute:

   psql -V

   the following response should be received:
   psql (PostgreSQL) 12.1 (Ubuntu 12.1-1.pgdg18.04+1)

   If you get an error message that the command was not found, install postgresql-client via the standard package manager. For Ubuntu, use this:

   sudo apt-get install postgresql-client

2. Find the path where postgresql is installed:

   which psql

3. Set a path to postgresql for SqlBak:

   sudo sqlbak -us -ps <your/path/to/psql>
