#110 Error when updating database

[Francisco Cribari]

Today I tried to update the lensfun database (which is used by Darktable lens correction module) and got the error messages below. I run Manjaro Linux.

Maybe the TLS certificate at wilson.bronger.org was invalid at that point in time? Anyway, it is valid now, and should be renewed automatically. (Certbot.)
