perl-DBD-Oracle and libdbd-oracle-perl packages shipped with ora2pgpro require Oracle Instant Client Package 12.1 (e.g. oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm). If you use Debian, note that the libdbd-oracle-perl package is not shipped with ora2pgpro as it is provided in the contrib section of the distribution. Its version for older systems (Debian 10, 11) uses the same version of Oracle Instant Client 12.1. The libdbd-oracle-perl package in Debian 12 requires Oracle Instant Client 21 or above (with package name oracle-instantclient-basic-xx.xx.x.x.x.x86_64.rpm). If you use a Debian-based system (Ubuntu, Astra Linux), you have to convert the RPM package to a Debian package using alien, and then install it using dpkg. You can download the packages here or from a different source and follow the installation instructions. Download the connection script pgpro-repo-add.sh. You can also do it using wget: $ wget --user your-username --ask-password https://repo.postgrespro.ru/ora2pgpro/keys/pgpro-repo-add.sh Run it with the rights of root. If your distribution is supported, the repository will be connected. Note that for a Debian-based system make sure to connect not only the main section but also the contrib section since it contains the required libdbd-oracle-perl package. Install the ora2pgpro package using your package manager. Depending on your system, it can be one of the following: apt-get: Debian, Ubuntu, Astra, AltLinux dnf: Red Hat Enterprise Linux (RHEL) systems and its derivatives: Red OS, Rosa yum: older Rosa versions zypper: SLES In any case, specify the parameters for install ora2pgpro. ora2pgpro binary packages are available for the following Linux-based systems: Debian-based systems: Debian 11/12/13, Ubuntu 22.04/24.04/26.04 Red Hat Enterprise Linux (RHEL) systems and its derivatives: Red Hat Enterprise Linux 8/9/10, Red OS Murom 7.3/8, ROSA Chrome 2021.1 ALT 10/11, ALT SP 8.2/10 SUSE Linux Enterprise Server (SLES) 15/16 MosOS 15
