Failed to edit crontab (linux Alpine)

I faced with an error during cron manipulation under my non-root account.

bash-4.3$ crontab -e
crontab: must be suid to work properly

Here is an output on id command:

bash-4.3$ id
uid=41532(fred) gid=41532(fred) groups=41532(fred),41532(fred)

Btw everything works for root account.
