[Letsencrypt-devel] Bug#867768: certbot: Fails to renew certs when a sytem call is interrupted

[Uwe Kleine-König]

Package: certbot
Version: 0.10.2-1
Severity: normal

Hello,

when I resize my terminal while certbot is trying to renew a
certificate, the process aborts with a message like:

	Cert is due for renewal, auto-renewing...
	Attempting to renew cert from /path/to/host.conf produced an unexpected error: HTTPSConnectionPool(host='acme-v01.api.letsencrypt.org', port=443): Max retries exceeded with url: /directory (Caused by NewConnectionError('<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x7f3339fa2910>: Failed to establish a new connection: [Errno 4] Interrupted system call',)). Skipping.

While this is not very grave (the process can just be repeated and if I don't
resize the window then, I get my new certificate). Still it would be nice if
that error could be handled without the need for user interaction.

Best regards
Uwe
