The following links are broken and we need replacements of fixes for them.

The main page builder did not find any broken link for the changed ones. Maybe they are buried in other places.

Thanks @ocefpaf! This link checker will be very helpful.

I'll update this photo link very soon. 11/9: I've updated the photo link (#216 )

(ohw22/espanol/index.es: line 14) broken https://udelar.edu.uy/directorio/lugares/centro-universitario-regional-del-este-cure-sede-rocha-1/ - HTTPSConnectionPool(host='udelar.edu.uy', port=443): Max retries exceeded with url: /directorio/lugares/centro-universitario-regional-del-este-cure-sede-rocha-1/ (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997)')))

This link is working. The error message is due to a SSL certificate validation failure. We could do nothing (ie, SSL validation failures will be exposed as errors), or alternatively, if possible, change the link checker to ignore SSL validation failures?

(ohw22/seattle/index: line 67) broken https://docs.google.com/presentation/d/17h4m6gTG8mRfWaQR3nOn6LPR3hQdCgWzH2hPzpCtyFU/edit#slide=id.p1 - Anchor 'slide=id.p1' not found

Hmm. This link is working. It's a Google slide presentation. Since the error involves the "Anchor 'slide=id.p1'", maybe removing "#slide=id.p1" from the url will make the link checker happy; I've verified that the link would still work. But I suspect that this is an issue that will be common with Google documents (docs/slides/sheets), so it may be a battle we can't win :thinking:

The next 3 links involve pages that are not actively being used in the web site. Nothing links to them, though Sphinx still renders them. We could delete the pages, ignore the link errors, or tweak the pages. In the meantime, I made one easy change to resources/projects/guidelines (commented out the broken link) to silence the error.
