FIXES#1564FIXES#1817
Tested by doing an LVM installation from KDE Neon, as described
in #1817. Installation was successful, and machine booted
successfully afterwards.
- when (manually) using an existing LV, it shouldn't be closed
prior to formatting, since that kills the volume and then the
path (/dev/myvg/mylv) no longer exists. Then creating the
filesysytem on that device path fails.
- Strings were being used as logical values, and then logged
(which should be in English) and also used in the UI (which
should be localized). Replace with a MessageAndPath class,
used only locally, that defers the translation until called-
upon explicitly.
- Replace some VG stuff with similar calls to apply().
Returning partition full-paths instead of only the block-device-name
simplifies later code -- which would prepend /dev/ to the block-
device-name and umount that.
- the tryX() functions weirdly return a string that is used for
debug-logging. Document that. The untranslated string is
later used for user-facing messages. Mark that as FIXME.
- factor out the loop-over-names-and-append to news, because that
makes the overall story of what is happening hard to read.
- all calls to tryCryptoClose() called tryUnmount() first, so
put that call inside tryCryptoClose(), so the interface is simpler.
- improve descriptive-strings in logging ("set?" is not very
meaningful)
- log only the unsatisfied entries, since the preceding
log-message suggests that that is what is happening.
QLabel allows scaling of the Pixmap by itself, and we have a
FixedAspectRatioLabel that scales a pixmap nicely. Use that.
(The new label type needed to be introduced to designer)
The screenshot should expand more agressively, so that it
does not get margins -- that just leave space around the
name and description -- when the window expands. Adjust some
of the stretching and layout in the UI file.
It is easier to put screenshots somewhere where
they can be searched-for, rather than requiring either
absolute paths (inconvenient to try out someone's
settings) or relative paths (because who knows where
Calamares will be run during testing).
