[Octave-bug-tracker] [bug #53841] Could not copy help collection to temporary file. Cannot load sqlite database driver!

[Sergey Bon.]

Follow-up Comment #21, bug #53841 (project octave):

I didn't read the whole discussion, so this may be mentioned already. But
anyway, here is the solution that worked for me. I run Octave 4.4.1 from the
Arch Linux repo.

Executing assistant on a file in readonly location fails due to bug:

$  assistant -collectionFile
/usr/share/octave/4.4.1/doc/octave_interpreter.qch
Error reading collection file
'/usr/share/octave/4.4.1/doc/octave_interpreter.qch': Cannot create index
tables in file /usr/share/octave/4.4.1/doc/octave_interpreter.qch..


_QHelpEngine fails to open collection in readonly location_
https://bugreports.qt.io/browse/QTBUG-73036

But executing it with sudo works fine and after doing this once Octave no
longer shows the error dialog:

$ sudo assistant -collectionFile
/usr/share/octave/4.4.1/doc/octave_interpreter.qch


I've also installed qt5-base and qt5-doc, but I'm not sure if that makes any
difference.
