looks like /snap/bin is not in your PATH ... did you already log out/in after the upgrade ?
(IIRC snaps puts a /etc/profile.d snippet in place to add to the PATH, that only gets processed on login)

[Andrea Bernabei (faenil)]

I have the snippet in /etc/profile.d, but /snap/bin is not in the PATH

[Andrea Bernabei (faenil)]

(Yes, I have already rebooted a few times after the upgrade)

Status changed to 'Confirmed' because the bug affects multiple users.

zsh sources /etc/zsh/zprofile by default. /etc/profile (and hence /etc/profile.d/) is only sourced in zsh's compatibility mode, i.e. when zsh is called as sh or ksh. At least Debian does not provide such symlinks and does not plan to do so in the future. (In contrary, Debian deliberately stopped being advertised as ksh alternative. And it never was advertised as /bin/sh alternative as the compatibility is not good enough for that, and also not meant to be good enough by upstream.)

Zsh in Debian has not (yet) implemented something like e.g. /etc/zsh/zprofile.d/ or so. So there's currently no way to add zprofile snippets via other packages. (Zsh in Debian though supports per-package vendor functions and completions.)

So from my point of view the only way to solve this issue from the zsh side is to provide a means for other packages to add snippets to zprofile. Once that's done, snapd needs to add an according snippet for zsh, too.

As a workaround, zsh users should update their $PATH manually in either /etc/zsh/zprofile (exists, only comments) or (as far as I can see) ~/.zprofile.
