This is an upstream regression very probably caused by: https://anongit.mindrot.org/openssh.git/commit/?id=65c6c6b567ab5ab12945a5ad8e0ab3a8c26119cc
I'd suggest filing it upstream at https://bugzilla.mindrot.org/ - it may be possible to preserve the intent of the above change by substituting a deliberately-locale-unaware version of tolower() when parsing configuration files, or maybe just by calling setlocale() after parsing configuration files. status triaged ** Changed in: openssh (Ubuntu) Status: Incomplete => Triaged -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1638338 Title: Can not ssh with tr_TR.UTF-8 locales (Bad configuration options) Status in openssh package in Ubuntu: Triaged Bug description: I can not ssh to any host with Turkish locales. What I expected to happen: I expected that 'ssh some_host' command would successfully run. What actually happened 'ssh some_host' command failed with an error. Steps to produce: 1. Open a terminal 2. Run LANG=tr_TR.UTF-8 ssh some_host If I run ssh with tr_TR.UTF-8 locale, the first error I get is: $HOME/.ssh/config: line 7: Bad configuration option: Identityfile $HOME/.ssh/config: terminating, 1 bad configuration options If I commend IdentityFile option from $HOME/.ssh/config file and re- run the command, I get this: debug1: Reading configuration data ~/.ssh/config debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * /etc/ssh/ssh_config: line 55: Bad configuration option: gssapIauthentication /etc/ssh/ssh_config: line 56: Bad configuration option: gssapIdelegatecredentials /etc/ssh/ssh_config: terminating, 2 bad configuration options If I commend GSSAPIAuthentication and GSSAPIDelegateCredentials option, I can ssh to a host. So to ssh to a host with tr_TR.UTF-8 locale, one must commend out IdentityFile, if it is used, GSSAPIAuthentication and GSSAPIDelegateCredentials optons.
