Shellckeck found errors in one or more shellscripts provided by sys-auth/pam_ssh. Kindly refer to the findings below and the shellcheck wiki for further details: ------------------------------------------------ script: /usr/portage/sys-auth/pam_ssh/pam_ssh-2.3.ebuild:64 for i in "${REPLACING_VERSIONS}"; do ^^^^^^^^^^^^^^^^^^^^^^^ error: Since you double quoted this, it will not word split, and the loop will only run once. (https://github.com/koalaman/shellcheck/wiki/SC2066) This is an automated bug report. Conservative settings were used to minimize false-positives but there's still a chance that the above list contains non-issues. Running shellcheck again with default settings could detect other possible issues. References: [1] this script: https://github.com/heeplr/gentoo-shellbug [2] shellcheck: https://www.shellcheck.net/
