Bug#944124: apt fails to verify certificate when using https and ocsp stapling
Package: apt
Version: 1.8.4
Severity: normal
Dear Maintainer,
We are running several debian repositories for custom kernel and patched deb
packages. We use apache2 on Buster, with https enabled, to serve the repos.
This worked fine, until we decided to enable ocsp stapling in apache2, which
runs other vhosts besides the repos.
Since then, apt fails to validate the server's certificate. Error message is:
Fehl:15 https://microscopium.de/repos/apt/debian/common buster/patched Release
Certificate verification failed: The certificate is NOT trusted. The received
OCSP status response is invalid. Could not handshake: Error in the certificate
verification. [IP: fd10:2842:f0d1:101:222:4dff:feb8:17c 8000]
Restarting apache2 helps for a while (apt works, at least once), but the error
comes up again when apt is run later.
All web tools tell us that certificate installation and ocsp stapling are
correct. No other problems with other https clients have been observed so far.
Our configuration uses squid-deb-proxy, but disabling the proxy does not
resolve the certificate problem.
