Many thanks for the  help and advice.

As well as installing zsh and powerlevel 10k on the gentoo install I have I
also did it with ubuntu.  Ubuntu is easier because prepared binary packages
are available to install things including the nerd fonts.

When i installed powerlevel10k using the omyzsh instructions I could get it
to run.

So I used the standard manual install instructions and it ended up in the
/root directory.  When I put that path into the .zshrc and ran exec zsh as
a user powerlevel 10k began to run.

The wizard ran and I set up a dozen or so prompt environment parameters and
at the end noticed a warning message:

Apply changes to ~/.zshrc?

   WARNING: ~/.zshrc is readonly and not owned by the user. Cannot modify
it.

(y)  Yes (disabled).

(n)  No. I know which changes to apply and will do it myself.

(r)  Restart from the beginning.
(q)  Quit and do nothing.

Choice [nrq]:


This meant I could not save the chosen options and carry on with them.

What sort of problem is this?

is it a file permissions problem?

I did not get that problem with the gentoo install.

Comments appreciated.

Regards
