Hello, all:

Now I've decided to write to devel@ mailing list to ask for help.

Currently, 5 Live spins:
* Fedora-Astronomy_KDE-Live-34-20210221.n.0 
https://koji.fedoraproject.org/koji/taskinfo?taskID=62419350
* Fedora-Scientific_KDE-Live-34-20210221.n.0 
https://koji.fedoraproject.org/koji/taskinfo?taskID=62419370
* Fedora-Security-Live-34-20210221.n.0 
https://koji.fedoraproject.org/koji/taskinfo?taskID=62419377
* Fedora-Cinnamon-Live-34-20210221.n.0 
https://koji.fedoraproject.org/koji/taskinfo?taskID=62419431
* Fedora-LXQt-Live-34-20210221.n.0 
https://koji.fedoraproject.org/koji/taskinfo?taskID=62419446
fail to be created due to the same bug:

Bug 1925922 - dependency loop with harfbuzz confuses 
xorg-x11-fonts-ISO8859-1-100dpi installation??
https://bugzilla.redhat.com/show_bug.cgi?id=1925922

Background (as far as I know)

With https://fedoraproject.org/wiki/Changes/EnableHarfBuzzInFreeType
https://bugzilla.redhat.com/show_bug.cgi?id=1906714 ,
on Fedora 34, freetype <=> harfbuzz depend on each other, causing dependency 
loop.
Now this is causing a problem - xorg-x11-fonts-ISO8859-1-100dpi has %postin 
scriptlet, which calls /usr/bin/mkfontdir
(which calls /usr/bin/mkfontscale) , which is in xorg-x11-font-utils , however 
at the time
%postin scriptlet of xorg-x11-fonts-ISO8859-1-100dpi is to be executed, 
"freetype" binary rpm
is not yet to be installed due to the dependency loop, which causes:

----------------------------------------------------------------
09:54:12,742 INF packaging: Configuring (running scriptlet for): 
xorg-x11-fonts-ISO8859-1-100dpi-7.5-27.fc34.noarch 1611907303 
d34990ca2d30c51a49e168a636361c94eb9ec4a4995ed5724c9aab2cea71ac1f
09:54:12,760 INF dnf.rpm: mkfontscale: error while loading shared libraries: 
libfreetype.so.6: cannot open shared object file: No such file or directory
warning: %post(xorg-x11-fonts-ISO8859-1-100dpi-7.5-27.fc34.noarch) scriptlet 
failed, exit status 127

09:54:12,761 ERR dnf.rpm: Error in POSTIN scriptlet in rpm package 
xorg-x11-fonts-ISO8859-1-100dpi
----------------------------------------------------------------
, which leads to live image creation failure for the above 5 spins.

Now freetype / harfbuzz maintainers asks xorg-x11-fonts-ISO8859-1-100dpi 
maintainer to
add some Requires(pre) dependency to "workaround" this issue - I wonder if this 
is the
"right" solution, however at least some action is needed.

Note that Fedora 34 beta freeze happens at 2021/Feb/23 14:00 UTC, so it is best 
that this issue can be
resolved soon. So - please someone look at this?


I've added a OrderWithRequires statement to tell RPM how to sort this:
https://src.fedoraproject.org/rpms/xorg-x11-font-utils/c/3f6e76ab132da44d2196c035492b34c37df4e4e8

That should help resolve this issue.


Unfortunately, this did not work.
e.g. Fedora-Astronomy_KDE-Live-34-20210222.n.0
     https://koji.fedoraproject.org/koji/taskinfo?taskID=62491131
(see "anaconda-packaging.log")

new xorg-x11-font-utils-1:7.5-49.fc34.x86_64 was pulled in, but freetype was
not installed at the time %postin scriptlet of
xorg-x11-fonts-ISO8859-1-100dpi-7.5-27.fc34.noarch ran.

Regards,
Mamoru
