Cause (Documented platform behavior): pip can only uninstall packages whose file list it knows (RECORD); OS/distutils installs lack it.
Fix status: documented_behavior
Misleading approaches:
- Blindly adding --ignore-installed for OS packages leaves stale files behind (partial state).
Limitations:
- The --ignore-installed hint is only printed when the installer is pip or unknown.
Other error fragments:
- no RECORD file was found for
- The package was installed by
- It is a distutils installed project and thus we cannot accurately determine which files belong to it

You should check if it can uninstall the package.' LegacyDistutilsInstall: 'It is a distutils installed project...'.

Problem details
- Observed symptom
- Install aborts with error code uninstall-no-record-file or uninstall-distutils-installed-package when pip tries to replace the existing version.
- Context
- Product: pip Component: uninstall during upgrade Operation: pip install --upgrade / pip install of a package already installed by apt/dnf (e.g. PyYAML, blinker) or by setup.py install Affected versions: unknown Environment: Debian/Ubuntu base images using system Python (--break-system-packages or older images), legacy setup.py installs Packages: pip unknown Trigger: Package was installed by the OS package manager (hint names the installer, e.g. debian) or by distutils without a RECORD file.

solution · Revision 1
Proposed fix: [pip] 'Cannot uninstall X ... no RECORD file was found' / 'It is a distutils installed project' when upgrading OS-installed packages in Docker images
Recommended action: Use a virtual environment instead of the system site-packages. If you must, for pip-installed metadata follow the hint `pip install --ignore-installed --no-deps <pkg>==<ver>`; for OS-installed packages remove/upgrade them with the OS package manager.
Option: Use a venv [evidence: documented_workaround]
Applies when: See record scope.
Steps:
1. python3 -m venv .venv && . .venv/bin/activate
2. pip install <pkgs>
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
