~$ sudo snap refresh firefox_edge

$ snap info firefox_edge | grep -i installed

I tried the following:

  • installing the stable snapd (from beta)
  • uninstall and reinstall it
  • check if parallel instances is enabled

When I reinstalled, I get this error:

$ sudo snap install --unaliased --edge firefox_edge
error: cannot perform the following tasks:
- Run hook connect-plug-host-hunspell of snap "firefox_edge" (run hook "connect-plug-host-hunspell":

I also checked if parallel instances is still working

$ sudo snap get system experimental.parallel-instances
true
