This bug is old but I'm going to un-duplicate it. I don't believe it is
fixed.
I've got a cron script on focal (cron 3.0pl1-136ubuntu1) which is
indirectly running `lxc` from a snap (/snap/bin/lxc).
I found the following in mail though:
/home/ubuntu/autopkgtest/tools/autopkgtest-build-lxd: 139: lxc: not found
/home/ubuntu/autopkgtest/tools/autopkgtest-build-lxd: 1: lxc: not found
crontab(5) mentions the default as being "/usr/bin:/bin", and how it
does NOT come from /etc/environment. What you have to do is set
"PATH=/snap/bin:/usr/bin:/bin" at the top of the crontab file if you
want to be able to use snaps. (You can't do "PATH=/snap/bin:$PATH"...)
pathnames.h has a #define for _PATH_DEFPATH where AFAICS this comes
from. Maybe it's that which we would want to modify to fix this for cron
in Ubuntu.
** This bug is no longer a duplicate of bug 1771858
/snap/bin not in default PATH for units, snapd should ship
system-environment-generators to inject /snap/bin into $PATH

Title:
Default cron PATH does not include /snap/bin
Status in cron package in Ubuntu:
Confirmed
Bug description:
I recently changed from a .deb install of LXD to a snap, and was
surprised that one of my crontab scripts stopped working.
I see that $PATH in a cron script only contains "/usr/bin:/bin",
whereas my default shell also includes "/snap/bin".
It seems to me that for the best user experience with snaps,
"/snap/bin" should be part of the default $PATH in cron.
