<div dir="ltr"><div>I recently installed Fedora Linux on a computer, and several
packages require that I have TeX Live installed through Fedora's package
system/repositories. However, the default paper size in this
distribution of TeX Live 2021 is A4, and I would like to change it to
Letter.</div><div><br></div><div>The command "tlmgr paper letter" does not seem to affect LuaTeX (specifically, LuaLaTeX) and fails with the following output:</div><div><br></div><div>> sudo tlmgr paper letter<br>tlmgr: setting paper size for dvipdfmx to letter: /usr/share/texlive/texmf-config/dvipdfmx/dvipdfmx.cfg<br>tlmgr: setting paper size for dvips to letter: /usr/share/texlive/texmf-config/dvips/config/<a href="http://config.ps" target="_blank">config.ps</a><br>tlmgr: setting paper size for pdftex to letter: /usr/share/texlive/texmf-config/tex/generic/tex-ini-files/pdftexconfig.tex<br>tlmgr: setting paper size for psutils to letter: /usr/share/texlive/texmf-config/psutils/paper.cfg<br>tlmgr: setting paper size for xdvi to letter: /usr/share/texlive/texmf-config/xdvi/XDvi<br>tlmgr: An error has occurred.

is almost certainly a Fedora TeX Live packaging issue, and it could be
resolved (I'm confident) by manually installing the binary TeX Live
distribution directly from TUG (which I have done many times before).
However, this is an undesirable solution because it may cause other
packages (that depend on TeX Live) to be "confused" and also would
result in twice the storage used (having side-by-side installations of
TeX Live).</div><div><br></div><div>My question is "how can I 'fix' this problem?". Specifically, are either of the following possible:</div><div><ul><li>Is
it possible to change the default paper size without having to use
tlmgr? Does tlmgr call/execute a particular command that could possibly
be executed manually?</li><li>Is it possible to set the default paper
size for Lua(La)TeX from the command line? For example, "lualatex
--defaultpapersize letter" (or similar)?</li></ul><div>Thank you in advance,</div><div><br></div><div>Troy Henderson</div></div></div>
