This is probably caused by you setting up / changing run-help in your ~/.zshrc. Can you confirm this?
I suggest using the following fix instead of your proposed patch: unalias run-help &>/dev/null Also, you might want to consider using this: % cat ~/.zshenv setopt noglobalrcs This would only source your ~/.zshrc, but not the files installed by the distribution. ** Changed in: zsh (Ubuntu) Importance: Undecided => Medium ** Changed in: zsh (Ubuntu) Status: New => Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/305346 Title: zsh error on startup: /etc/zsh/zshrc:unalias:43: no such hash table element: run-help To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zsh/+bug/305346/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
