Repositories

The repo command group enables package repositories required by some Abstrax features on RHEL-family systems (Rocky Linux, AlmaLinux, RHEL, CentOS Stream, Oracle Linux).

Debian/Ubuntu systems do not need this command for current Abstrax features.

abstrax repo <action>

Permissions

repo enable requires root.

Global flag

Flag	Description
`--enable-required-repos`	Allow enabling policy-sensitive third-party repositories (EPEL, Remi, etc.) from other commands such as `project add` or `ssl install`

On RHEL and Oracle Linux, abstrax repo enable for EPEL/Remi also requires --enable-required-repos or --yes to confirm intent.

`repo enable`

Enable a named repository.

sudo abstrax repo enable epel
sudo abstrax repo enable crb
sudo abstrax repo enable remi --enable-required-repos

Repository	Purpose
`epel`	Extra Packages for Enterprise Linux (Certbot; Remi dependency)
`crb`	CodeReady Builder / CRB (Remi dependency on EL9)
`remi`	Remi repository for multi-version PHP (Software Collections)

Behaviour by distro

Rocky / AlmaLinux / CentOS Stream: EPEL and CRB may be enabled when a command needs them (EPEL for Certbot automatically; Remi still requires --enable-required-repos or this command).
RHEL / Oracle Linux: EPEL and Remi require explicit consent via abstrax repo enable … --enable-required-repos or by passing --enable-required-repos to the command that needs the repo.

Abstrax prints clear output when enabling repositories and will not silently add third-party repositories on enterprise distributions.

Remi and PHP

Multi-version PHP on RHEL-family systems uses Remi SCL packages. Before installing PHP via project add / project modify, either:

sudo abstrax repo enable remi --enable-required-repos
sudo abstrax project add app --php --php-version=8.3

or:

sudo abstrax project add app --php --php-version=8.3 --enable-required-repos
