APT

Linux package managers install packages with root privileges, creating a security risk where a compromised package source can execute arbitrary code with full system access without proper sandboxing or isolation.

Different Linux distributions use incompatible package formats (RPM, .deb, Pacman) and package managers, forcing developers to maintain separate builds and repackage for each distro. This creates significant resource overhead, especially for small teams.

APT uses a global lock file that prevents parallel package installations from multiple terminals, creating a serious usability limitation when attempting concurrent package management operations.
