在 Fedora 39 系统上，我收到以下错误：
kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 eurm10
mktexpk: don't know how to create bitmap font for eurm10.
mktexpk: perhaps eurm10 is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.
(see the transcript file for additional information)
!pdfTeX error: pdflatex (file eurm10): Font eurm10 at 600 not found
我四处寻找，在 Arch 论坛上看到了一篇 2020 年的帖子，上面说我可能需要texlive-most，但这在 Fedora 39 上不可用。但是，texlive-amsfonts是可用的，并且提供了
/usr/share/texlive/texmf-dist/fonts/afm/public/amsfonts/euler/eurm10.afm
/usr/share/texlive/texmf-dist/fonts/tfm/public/amsfonts/euler/eurm10.tfm
/usr/share/texlive/texmf-dist/fonts/type1/public/amsfonts/euler/eurm10.pfb
/usr/share/texlive/texmf-dist/fonts/type1/public/amsfonts/euler/eurm10.pfm
我不太明白如何解决此错误。我尝试了以下方法： TeX：mktexpk：不知道如何创建位图字体
$ sudo texhash
texhash: Updating /usr/share/texlive/texmf-config/ls-R...
texhash: Updating /usr/share/texlive/texmf-dist/ls-R...
texhash: Updating /usr/share/texlive/texmf-local///ls-R...
texhash: Updating /var/lib/texmf/ls-R...
texhash: Done.
进而：
sudo updmap-sys
并遵循@UlrikeFischer 的建议：
$ sudo updmap-sys --enable Map=euler
updmap will read the following updmap.cfg files (in precedence order):
/usr/share/texlive/texmf-config/web2c/updmap.cfg
/usr/share/texlive/texmf-dist/web2c/updmap.cfg
updmap may write changes to the following updmap.cfg file:
/usr/share/texlive/texmf-config/web2c/updmap.cfg
/usr/share/texlive/texmf-config/web2c/updmap.cfg unchanged. Map files not recreated.
updmap: updating ls-R files.
然后我查看了这个文件：
$ grep eurm10 /usr/share/texlive/texmf-config/web2c/updmap.cfg
#! Map eurm10.map
#! Map eurm10
看起来它被注释掉了。也许这就是问题所在。为什么它被注释掉了？
但是，取消注释会产生类似但略有不同的错误：
kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+2/600 --dpi 602 eurm10
mktexpk: don't know how to create bitmap font for eurm10.
mktexpk: perhaps eurm10 is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.

$sudo updmap-sys
...

但还是找不到字体。
我尝试了以下hello.tex示例：
\documentclass[a4paper]{article}
\begin{document}
Hello world!
\end{document}
但这里没有显示错误：
