Package: dropbear-bin Version: 2018.76-4 The dropbear binary has the path for the sftp server hardcoded as "/usr/libexec/sftp-server". However, the openssh-sftp-server package installs the sftp server to "/usr/lib/openssh/sftp-server" and creates a link at "/usr/lib/sftp-server". The package lsh-server installs its sftp server to "/usr/lib/lsh-server/sftp-server".
I don't see any packages that install to or create links at the path hardcoded by dropbear ("/usr/libexec/sftp-server").
