Marked for autoremoval on 22 September: #1143939 high

Version 1.4.5+dfsg-3 of clamav is marked for autoremoval from testing on Tue 22 Sep 2026. It is affected by #1143939. The removal of clamav will also cause the removal of (transitive) reverse dependencies: c-icap-modules, clamassassin, clamsmtp, clamtk, cyrus-imapd, e2guardian, libclamunrar, pg-snakeoil. You should try to prevent the removal by fixing these RC bugs.

This package will soon be part of the auto-openssl transition. You might want to ensure that your package is ready for it. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
excuses:
- Migration status for clamav (1.4.5+dfsg-3 to 1.4.6+dfsg-1): Waiting for test results or another package, or too young (no action required now - check later)
- Issues preventing migration:
- ∙ ∙ Autopkgtest for apparmor/4.1.8-1: amd64: Pass, arm64: Pass, armhf: Failed (not a regression) ♻ (reference ♻), i386: Failed (not a regression) ♻ (reference ♻), ppc64el: Pass, s390x: Test triggered

- ∙ ∙ Autopkgtest for pg-snakeoil/1.4-4: amd64: Pass, arm64: Pass, ppc64el: Pass, s390x: Test triggered
- ∙ ∙ Lintian check waiting for test results on riscv64 - info
