siavoshkc [1] filed a deletion request for stable-diffusion-ui [2]:
This package does not follow security best practices by being too
permissive on the permissions given on /opt/${pkgname}
The package also really installs an installer and has no control over
of what that installer does afterward.
This way of packaging is not supported by upstream and security
implications are unavoidable as a result of its design.
