Hi everybody! After updating my openSuSE Tumbleweed system I found lualatex broken. "lualatex somefile" led to an error message: LuaHBTeX, Version 1.12.0 complained that "lualatex.fmt was written by luatex".
Removing lualatex.fmt did not fix the problem. "fmtutil --all" did not fix the problem. Then I changed the lualtex entry in /etc/texmf/web2c/fmtutil.cnf to "lualatex lua*hb*tex language.dat,language.dat.lua lualatex.ini" and started "fmtutil --all" again. That fixed the problem, but I suspect that I only found a quick workaround. Is this a general TeXLive 2020 problem or an openSuSE bug? Knut
