In dmesg log, i saw a line starting with "mar 20 02:04:10 eduapps whoopsie-upload-all[8574]" which was written by whoopsie that gave me a brave crash log.
brave crash log is big but gives good info of what's going on. if you search for the word "SIGSEGV" you will find where the error occurs. ** Attachment added: "dmesg log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2058191/+attachment/5757403/+files/journalctl.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2058191 Title: Getting SIGSEGV and SIGILL in many programs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/2058191/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
