Moved from TexLive 2018 to 2020 and now I'm getting countless font errors

Question

After sticking with TexLive 2018 for over two years, I decided to move on to TexLive 2020. I followed the instruction here, changed my path to point to the new TexLive directory, rebooted and so on. I ran sudo fc-cache -fv. I attempted to update the install through tlmgr, just in case, but I already had every single package installed and updated (except four that have "Windows" in their names).

In spite of all of the above, now when I try and use TexLive 2020 to compile documents that were working yesterday with TexLive 2018, I get uncountable errors, mostly related with fonts.

missfont.log shows only missing fonts:

The document's compilation log has many more problems. It's 1 MB+, so I'm including some highlights here.

In spite of not appearing in missfont.log, there are these errors:

! Package fontspec Error: The font "Linux Libertine O" cannot be found.
! Package fontspec Error: The font "Linux Biolinum O Bold" cannot be found.
! Package fontspec Error: The font "Libertinus Sans" cannot be found.
! Package fontspec Error: The font "LatinModernMath-Regular" cannot be found.

A more detailed version of one of those error messages is here:

I do have have this font on my system. In my TexLive directory tree. In fact, there are over 5300 files relating to it. Here is a small sample, cut down due to the SX character limit:

And yet, fc-list | grep -i libertine doesn't produce anything at all.

How do I fix this? In the past, I was always able to fix LaTeX font problems with sudo fc-cache -fv, but not that's not doing the trick.

EDIT: Some system info:

OS:

Kubuntu 20.04

Latex version:

pdfTeX 3.14159265-2.6-1.40.21 (TeX Live 2020)

kpathsea version 6.3.2

...

Compiled with libpng 1.6.37; using libpng 1.6.37

Compiled with zlib 1.2.11; using zlib 1.2.11

Compiled with xpdf version 4.02

Install type:

Vanilla TexLive 2020, as root.

Compiler:

XeLaTex

You seem to be running Linux, so you probably need to update your font configuration to index your TeX Live 2020 directory instead of the old path. I wrote some instructions for Debian/Ubuntu here. — Davislor, Nov 21 '20 at 03:55
If you’re running LuaTeX, you also want to run sudo luaotfload-tool -f -u -p -v. — Davislor, Nov 21 '20 at 03:56
@Davislor I'm running Kubuntu 20.04, yes. Installed TexLive as root, as I always have. I had purged all Ubuntu versions of Tex things years ago, pure vanilla TexLive since then. Using XeLaTeX. My paths are set as per your nice tutorial. My new install (TL2020) is in a separate directory from TL2018, so even if the paths haven't been updated, these fonts should be found. — Gil Williams, Nov 21 '20 at 04:43
Right, but you need to copy the configuration file to the right directory for fc-cache to know to search them. If you run it with -v`, does it list any of those directories in its search? — Davislor, Nov 21 '20 at 04:53
@Davislor I just followed your tutorial, and adding my TeX tree to the system font paths seems to have solved some of the problem. However, now I'm getting truly bizarre errors that I didn't used to get, in files that aren't even mine, e.g. in amssymb.sty I get "Command `\eth' already defined. ...ol{\eth} {\mathord}{AMSb}{"67}", as well as in my own files "Missing font identifier. ...s not specify its(microtype) \fontdimen 6 (". Plus a couple hundred errors about illegal units of measure and missing numbers and such. Could this solution have only partially fixed things? — Gil Williams, Nov 21 '20 at 05:01
@Davislor fc-cache -v returns three Libertine paths: /usr/share/fonts/opentype/linux-libertine, /usr/local/texlive/2020/texmf-dist/fonts/opentype/public/libertine, /usr/local/texlive/2020/texmf-dist/fonts/type1/public/libertine. It also returns hundreds with errors, like "/usr/local/texlive/2020/texmf-dist/fonts/type1/public/amsfonts/cm: skipping, looped directory detected". This persists even after sudo fc-cache -rv — Gil Williams, Nov 21 '20 at 05:03
I would try the following: 1. Make sure that all TeX Live 2018 files are removed from your font path and configuration directory, 2. find your local caches with ls -a ~ and clear them; they’ll have names like .texlive2020, 3. Make sure you're running the correct fc-cache, and 4. Run fc-cache -r -s -v and sudo $(which updmap-sys). — Davislor, Nov 21 '20 at 05:06
Actually, probably simpler to just wipe TeX Live and do a clean reinstall. It sounds as if you're somehow mixing old and new TeX Live files. — Davislor, Nov 21 '20 at 05:10
If you check the .log file for the run that was giving you errors, is it looking up any files from a different version of TeX Live, or is it getting them all from the correct tree? — Davislor, Nov 21 '20 at 05:13
No references to TL2018 in the log file. I've tried fc-cache -r -s -v and sudo $(which updmap-sys), but no joy. I'm going to try a fresh install again. This is too much of a mess. Thanks! Will report back. — Gil Williams, Nov 21 '20 at 05:35
Another thing tlmgr should take care of is sudo $(which texhash), but it doesn’t sound as if the system’s got any old filenames cached there. — Davislor, Nov 21 '20 at 05:53
Amd ,ale sire you don't have any other copies installed, such as the texlive-base apt package. — Davislor, Nov 21 '20 at 06:01
I doubt that your follow up problem is an installation problem, better a small complete example, so that we can test if we get the error too. — Ulrike Fischer, Nov 21 '20 at 07:47
Reinstalled from absolute scratch, as user, following tutorial above. Fonts detected as well as last time after I did the symlink, but a MASSIVE number of errors still occur. Will make a separate question. Thanks to all. — Gil Williams, Nov 21 '20 at 08:14

Moved from TexLive 2018 to 2020 and now I'm getting countless font errors
