Re: [gscan2pdf-help] scantpaper v3.0.6 released

[Alan D. <ala...@gm...>]

I have attempted to install scantpaper v. 3.0.6 on CachyOS, an archlinux
derivative.

Unlike my previous attempt, I was able to install tesserocr, after which
scantpaper moved on to another missing dependency: goocanvas2.  After this
( downgrade from the installed goocanvas 3 version), scantpaper tried
again.  The next message is beyond my understanding.  Perhaps it will be of
some interest?

Ubuntu is not a rolling release distro, so one kind of expects these
failures to use up to date dependencies.  Probably, eventually things will
settle down.  This is an improvement, I think.  CachyOS keeps up with
upstream, as far as I can tell.
