I choose to set an expiry date on my gpg keys. 6 month is good enough for me to not forget everything in-between.

gpg2 --edit-key B8EC0946
expire
[...]
key $SUBKEY
expire
[...]
save

But (almost) every time I try to send the updated key to the keyserver, I get an error. This time :

gpg: sending key 0xC684F06AB8EC0946 to hkp://keyserver.ubuntu.com
gpg: keyserver send failed: Buffer too short
gpg: keyserver send failed: Buffer too short

Searchng the web with this error message gives absolutely nothing. Nobody ever gets a « buffer too short » error ?

I was sure that was a local error. But blindly trying random options, I run

gpg2 --keyserver hkps://keyserver.ubuntu.com:443 --send-keys B8EC0946

And this work !?

gpg: envoi de la clef 0xC684F06AB8EC0946 à hkps://keyserver.ubuntu.com:443

So in conclusion, set keyserver hkps://keyserver.ubuntu.com:443 (hkp over TLS) in ~ /.gnupg/gpg.conf and voilà !

Hello to Gnupg maintainer and/or keyserver.ubuntu.com maintainer :
