Public bug reported:
On Ubuntu 26.04 "File > Send > Document as E-mail" in LibreOffice opens the mail
composer without the attachment (and without the subject).
The AppArmor profile /etc/apparmor.d/libreoffice-senddoc allows
/usr/bin/dirname, /usr/bin/basename and /{usr/,}bin/uname, but with
coreutils-from-uutils these are symlinks to /usr/lib/cargo/bin/coreutils/*,
and AppArmor checks the resolved target. senddoc therefore cannot run them:
senddoc: 20: dirname: Permission denied
senddoc: 22: uname: Permission denied
senddoc: 66: basename: Permission denied
senddoc: 325: /uri-encode: not found
apparmor="DENIED" operation="exec" class="file" profile="libreoffice-senddoc"
name="/usr/lib/cargo/bin/coreutils/basename" comm="senddoc" requested_mask="x"
denied_mask="x"
Because URI_ENCODE=$(dirname "$0")/uri-encode fails, the subject and the
attachment are lost and the mailer is called with just "subject=".
This is the same class of problem as LP: #2123870 (the bug description lists
the senddoc profile), but libreoffice has no task there and the profile is
still unfixed.
Steps to reproduce:
1. Ubuntu 26.04, default mail client Thunderbird.
2. Open any document in Writer, File > Send > Document as E-mail.
3. Composer opens without attachment; see DENIED messages in journalctl -k.
Suggested fix: use the @{coreutil_dirs} tunable
(/etc/apparmor.d/tunables/coreutils)
like the other profiles fixed in LP: #2123870, e.g.
@{coreutil_dirs}/{dirname,basename,uname} rmix,
Workaround: /etc/apparmor.d/local/libreoffice-senddoc with
/usr/lib/cargo/bin/coreutils/basename rmix,
/usr/lib/cargo/bin/coreutils/dirname rmix,
/usr/lib/cargo/bin/coreutils/uname rmix,
and apparmor_parser -r /etc/apparmor.d/libreoffice-senddoc.
Related: the profile only allows xdg-email/xdg-open, so setting the mail
program explicitly (e.g. /usr/bin/thunderbird) in Tools > Options > Internet >
E-mail is also denied.
