• Product: Portage Development
• Status: UNCONFIRMED ---

[Description Anthony Ryan 2024-06-19 20:33:42 UTC]

# I observed that the www-servers/nginx in an overlay failed to satisfy virtual/httpd-cgi


# Clean stage3

location = /var/db/repos/test-overlay

# Setup keywords
echo 'app-misc/mime-types nginx' > /etc/portage/package.use/test
echo 'www-servers/nginx' > /etc/portage/package.accept_keywords/test

# Break dependency resolution
emerge www-servers/nginx::test-overlay virtual/httpd-cgi -v

# www-servers/nginx::test-overlay should satisfy virtual/httpd-cgi
# but does not and we wind up with the slot constraints 0 blocking
# mainline and mainline blocking 0 creating a situation it can't
# resolve independently even though it's already been met.

Also to clarify, the emerge version in the that stage3 is:

emerge --version
Portage 3.0.63 (python 3.12.3-final-0, default/linux/amd64/23.0, gcc-13, glibc-2.39-r6, 6.9.4-gentoo x86_64)
