<!-- Please read our Bug reporting guidelines before opening a bug: https://wiki.archlinux.org/title/Bug_reporting_guidelines If you want to help catching more bugs upfront, consider joining the Arch Testing Team: https://wiki.archlinux.org/title/Arch_Testing_Team --> # Description: <!-- Describe the bug in full detail. --> After upgrading openssh, the service seems broken. sshd immediatly closes the connection and logs: > sshd: -R not supported here The client just sees: > kex_exchange_identification: read: Connection reset by peer This is fixed by restarting sshd, but for remote systems this MUST be done in the same session where the upgrade took place, otherwise you'll be locked out. It'd probably be good to add a post_upgrade warning about this. # Additional info: * package version(s): openssh 9.8p1-1 * config and/or log files: sshd: -R not supported here * link to upstream bug report, if any: could not spot the change causing this in ChangeLog # Steps to reproduce: <!-- Describe how to reproduce the bug step by step including the commands --> 1. Upgrade openssh to 9.8p1-1 with sshd running (keep session open) 2. Try to login => connection reset by peer 3. Restart sshd 4. Try to login => works again
