Hello,
I just test with the following update steps:
# sudo -u www-data composer update -W
# sudo -u www-data composer update -W horde/horde:6.x-dev
# sudo -u www-data composer update -W horde/imp:7.x-dev
# sudo -u www-data composer update -W horde/core:3.x-dev
# wget
https://github.com/horde/Core/archive/refs/heads/test/imp88-readonly-download-auth.zip
# unzip imp88-readonly-download-auth.zip
# cp -rf Core-test-imp88-readonly-download-auth/* vendor/horde/core/
# chown www-data:www-data -R vendor/horde/core/*
Problem is still there.
Best regards
Angel
