Package: calibre Version: 5.26.0+dfsg-2 Severity: normal Dear Maintainer,
Installing calibre 5.26.0+dfsg-2 on a system with pypy3 7.3.5+dfsg-2 installed produced the following message: Setting up calibre (5.26.0+dfsg-2) ... Failed to byte-compile /usr/lib/calibre/calibre/utils/formatter.py: File "/usr/lib/calibre/calibre/utils/formatter.py", line 928 if v := self.expr(expr): ^ SyntaxError: invalid syntax It appears that /var/lib/dpkg/info/calibre.postinst contains 2 calls to py3compile and pypy3compile for /usr/lib/calibre, first with -V 3.7-, then with -V 3.9: -8<--[calibre.postinst from line 28]---------------------------------- if which py3compile >/dev/null 2>&1; then py3compile -p calibre /usr/lib/calibre -V 3.7- fi if which pypy3compile >/dev/null 2>&1; then pypy3compile -p calibre /usr/lib/calibre -V 3.7- || true fi # Automatically added by dh_python3 if which py3compile >/dev/null 2>&1; then py3compile -p calibre /usr/lib/calibre -V 3.9 fi if which pypy3compile >/dev/null 2>&1; then pypy3compile -p calibre /usr/lib/calibre -V 3.9 || true fi if which py3compile >/dev/null 2>&1; then py3compile -p calibre /usr/share/calibre -V 3.9 fi if which pypy3compile >/dev/null 2>&1; then pypy3compile -p calibre /usr/share/calibre -V 3.9 || true fi -8<--[calibre.postinst]----------------------------------------------- On my system, `pypy3compile -p calibre /usr/lib/calibre -V 3.7-` produces the error. It appears that removing the calls to py3compile and pypy3compile from debian/calibre.postinst in favor of the ones added by dh_python3 would avoid the issue.
