* Update base image to Ubuntu 24.10. This uses a python version where j2cli no
longer works when installed using pip so use the version from Ubuntu instead
which has been patched to work.
* Update shellcheck, pylint, pytest, isort, flake8, black and yamllint to the
latest versions. This closes#502.
* Use a longer expect timeout to fix tests failing when gpg is killed due to
this timeout.
* Explicitly flush gpg-agent's cached passwords to fix failing tests with
latest gnupg. Also clean up after tests to avoid having gpg-agents running
after the test (e.g. when running tests directly without docker).
This makes it possible to run e.g. "yadm -Y foo introspect repo
2>/dev/null" and get an empty output instead of getting the error
message about foo not being fully qualified.
Start with doing "submodule absorbgitdirs" as otherwise "submodule
deinit" will fail if a module has been cloned first and later added as
a submodule (as it will then contain the .git dir instead of it being
under the superprojects .git dir).
Then try to deinit the submodules before moving the repo and abort the
upgrade if it fails for any submodule. Then do the move and finally
initialize the submodules that were initialized before the upgrade.
See #285
