if you apply the "qt_api = 'PyQt5' instead of qt_api = 'PyQt6'" fix, does the Patchqueue feature in tortoisehg work?

here: it does not

I think the problem is you have to ensure you don't have python-pyqt5 installed while you're building tortoisehg. You can reinstall it if you need to afterwards.

confirming jack_stone's issue.
same here,
proposed fix works also

Had a little problem today after update:

Not sure why, but /usr/lib/python3.14/site-packages/tortoisehg/util/config.py ended up having qt_api = 'PyQt5' instead of qt_api = 'PyQt6' which I expect is correct (tortoisehg works after I had changed it manually).

Is it possible that problem was that I have python-pyqt5 installed, which somehow poisoned the Qt API detection? Not sure if it's packaging issue. At any rate, maybe this helps a next person.

edit: formatting

It looks like stable branch should now work with mercurial 7.2: https://foss.heptapod.net/mercurial/tortoisehg/thg/-/work_items/6042#note_510476 But for now my workaround is to replace mercurial with v 7.1.2, and it works.

sudo pacman -Rsdd mercurial OR pip uninstall mercurial then pip install mercurial==7.1.2

python-qscintilla-qt5 is no longer in the AUR. Arch repo has python-qscintilla-qt6 but not 5. There's QScintilla pypi.org, which says it's for PyQt5, but I don't know whether tortoisehg would find it ...

I uninstalled mercurial with pacman, then installed mercurial 6.9 with pip install --user. Thg now opens OK (from plasma menu) and opens a saved repo OK, but I haven't actually used it yet. Running hg from command line gets an error "(most likely due to a circular import)", but I never use its CLI.

Opening Tortoisehg just gives me a Error dialog stating: "this version of TortoiseHg requires Mercurial version 6.3.n to 6.9.n, but found 7.2.1"

and some more output:

thg has still some issues with Qt6.
