You have a local network issue. At least something wrong with your DNS settings. Do you use a local DNS server?

No, I do not have a DNS server.

[MichaIng]

Which DNS server are you using?

cat /etc/resolv.conf

Does it help, in case, to switch to a public one?

echo 'nameserver 1.1.1.1' > /etc/resolv.conf
apt update

[Joulinar]

can you check the one configured

cat /etc/resolv.conf

[boterocamilo]

can you check the one configured

cat /etc/resolv.conf

nameserver 147.78.28.2
nameserver 147.78.28.10

Seems to be a local ISP, probably it has temporary issues. See whether the using Cloudflare (above) does better.

did you configure them manually? They seem to be unreachable

apt update

I did change it manually as suggested. These are now the errors when running apt update:
