I faced the problem when terminal do not start. I have look at related issue when locale do not supported. I have tried to update it, regenerate it - nothing help. Finally I have found next error message in /var/log/syslog

Here is not clear. If I have wrong locale which locale is not supported?? How to check which locales are supported? How to apply supported locale?
