Ubuntu Zsh (via Vagrant) does not find Zsh or its functions

Question

I have a wagrant provisioning script that tries to install Zsh if it is not available, and then change the shell to use Zsh.

There are two questions that I think I have:

Firstly, I do not believe that the shell will change to Zsh, because when I start vagrant sshto access Ubuntu VM, and after starting the ps -p $$command indicates that Bash is the shell that is running (where I would expect Zsh).

The second problem is that if it changes to the Zsh shell (regardless of what ps -p $$reports it returns), then Zsh displays a lot of errors when I run the .zshrc file, which assumes that the specified functions are missing or simply not referencing correctly.

---

I will break it into steps by performing a Zsh installation manually, and not through setting up a Vagrant script ...

• cat /etc/shells → I do not see links to Zsh †
• sudo apt-get update
• sudo apt-get install zsh ≠
• cat /etc/shells→ now have /bin/zshand/usr/bin/zsh
• which zsh → /usr/bin/zsh
• zsh --version → zsh 5.0.2 (x86_64-pc-linux-gnu)
• chsh -s $(which zsh)
• source .zshrc → Lots of errors sent to stdout ~~
• tree /usr/share/zsh/→ see below ** for output, but the notification is functionnot inside the directory 5.0.2?

I think it is more likely that Zsh does not change, because if I execute the command zsh, I get into a new shell environment, and if I run source .zshrc, I will not get errors. Also, if I run ps -p $$, now I will see that Zsh is reported as a running shell.

At the end of this question, you can find all my settings for a stroller script.

† The list of shells that I see is:

/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/usr/bin/tmux
/usr/bin/screen
