Fix letsencrypt symlinks from /live to point to correct /archive entry

script.py

#!/usr/bin/env python3

# Just run this program. It'll find all 'archived' letsencrypt certs, 
# and sets up the corresponding live/ entries.
# This solves the following error:
# CertStorageError: expected /etc/letsencrypt/live/example.com/cert.pem to be a symlink

import os
import re

maindir = "/etc/letsencrypt"

archived_entries = {}

for dirpath, dirnames, filepaths in os.walk(maindir + "/archive"):
	if len(filepaths) == 0: continue
	print("Found dir %s" % (dirpath))
	
	for filepath in filepaths:
		m = re.search(r'([^0-9]+)(\d+)\.pem', filepath)
		if not m: continue
		entry = dirpath.replace("/archive", "/live") + '/' + m.group(1) + '.pem'
		idx = int(m.group(2))
		if entry not in archived_entries:
			archived_entries[entry] = {
				'lastver': 0,
			}
		
		if archived_entries[entry]['lastver'] < idx:
			archived_entries[entry]['lastver'] = idx
			archived_entries[entry]['path'] = dirpath + '/' + filepath


for entry, data in archived_entries.items():
	print('%s (v%d) -> %s' % (entry, data['lastver'], data['path']))
	os.remove(entry)
	os.symlink(data['path'], entry)
