failed to edit cheatsheet: fork/exec /usr/bin/editor: permission denied

A description of the problem
I am using Ubuntu 22.04 and just installed cheat via snap. Upon trying to edit a cheatsheet, I get the following error:

foo@asdf:~$ cheat -e yt-dlp
failed to edit cheatsheet: fork/exec /usr/bin/editor: permission denied

I am semi-sure this is caused by snap restricting the rights of the packages it installs. I do not have the error above when using the downloaded binaries

cheat version info

foo@asdf:~$ cheat -v
4.4.0

Hi @YueRen
your assumption is correct. What editor are you using?
The snap supports vim and nano.

@bernermic The error seems to be editor-independent

I remember trying to change editor: /usr/bin/editor to editor: emacs in .config/cheat/conf.yml to no avail.

/usr/bin/editor is nano 6.2 on my system.

I've transferred this from cheat/cheat, given that this pertains to the Snap specifically. The answer to this issue may simply be that only vim and nano are supported, and if that's the case, feel free to close this ticket.

It is perfectly fine to only support vim or nano. There is however one small stumbling block that users should be aware of:

Upon first use, cheat auto-generates the configuration file ~/snap/cheat/common/.config/cheat/conf.yml, and it seems to set editor to whatever $EDITOR is (at least it did for me on a new laptop running Ubuntu 25.04). This could lead to an error when users try to edit their cheat sheets using cheat -e foo. Should that be the case, just manually set editor to either /usr/bin/editor (for vim) or nano.
