Hi, > pkg: No SRV record found for the repo 'FreeBSD-base' Generally this switch helps to overcome that (if its not DNS issue): - url: "pkg+https://pkg.FreeBSD.org/${ABI}/base_release_${VERSION_MINOR}", + url: "https://pkg.FreeBSD.org/${ABI}/base_release_${VERSION_MINOR}", - mirror_type: "srv", + mirror_type: "none", Details here: - https://vermaden.wordpress.com/2026/01/07/freebsd-and-poudriere-in-high-security-environments/ > The older packages are actually still there, but there's no way for you to find them. I would consider enabling 'dirlisting' for all pkg(8) related repositories ... this 'blindness' does not help - it has been reported many times that how many 'workarounds' one needs to do to manually fetch needed pkg(8) package.
