१३.१० से १४.०४ में अपग्रेड करने के बाद से, मुझे हर बार इंस्टॉल, अपडेट, अपग्रेड, और इसी तरह ये कष्टप्रद संदेश मिलते हैं:

मैं संदेश में बताई गई अंतर्निहित समस्या को कैसे ठीक करूं?
संपादित करें: कभी-कभी, मुझे उपरोक्त संदेशों के लिए अतिरिक्त संदेश मिलते हैं:
W: GPG error: http://www.duinsoft.nl debs Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E18CE6625CB26B26
W: Failed to fetch http://ppa.launchpad.net/person/ppa/ubuntu/dists/karmic/main/binary-amd64/Packages 404 Not Found
W: Failed to fetch http://ppa.launchpad.net/person/ppa/ubuntu/dists/karmic/main/binary-i386/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.
और कभी-कभी, मैं दूसरों को दे सकता हूं, लेकिन मुझे अब सटीक संदेश नहीं मिल सकते हैं।
