View Full Version : [ubuntu] Cannot encrypt mail with Thunderbird

May 17th, 2008, 05:53 PM
After updating from 7.10 to 8.04 I cannot send signed mails with Thunderbird (whole error window is attached).
After trying everything I could, including forum entries for similar problems, I decided to do a clean install on a different computer.

Same error! Incredible!

Any ideas?
