Marking as Invalid as that seems expected: strace uses ptrace which does
not work across setuid/setgid binaries which crontab is.
-rwxr-sr-x 1 root crontab 43K Jun 6 2024 /usr/bin/crontab
This is intended for security (otherwise it would be trivial to hijack
`su`).
** Changed in: strace (Ubuntu)

Title:
strace crontab -e bombs on 10.04LTS
Status in strace package in Ubuntu:
Invalid
Bug description:
Binary package hint: strace
strace is doing something wrong and winds up modifying the behavior of
a running program -- in short, running "crontab -e" works fine, but
running "strace crontab -e" results in an error being thrown before
the editor is even invoked.
'crontab -e' returns an exit value of 0
'strace crontab -e' returns an exit value of 1
This reproducible on a fresh, up to date 10.04 LTS 64-bit install and
verified on a machine that was upgraded a few times.
I set EDITOR=cat below to remove most of the binary ncurses noise of
my default editor (nano).
