क्यों ताजा Ubuntu के बाद 12.04 स्थापना अद्यतन स्थापित नहीं किया जा रहा है?

Question

मैंने एक कंप्यूटर पर Ubuntu 12.04 स्थापित किया है। अपडेट के बिना सबकुछ ठीक है। स्थापना के ठीक बाद, यह डाउनलोड करने के लिए लगभग 200 एमबी अपडेट दिखा रहा था। तब से मैं सभी अपडेट इंस्टॉल करने का प्रयास कर रहा हूं। अब यह आंशिक रूप से पूरा हो गया है, कुछ सॉफ्टवेयर (फ़ायरफ़ॉक्स, वीएलसी) को अपडेट किया गया है। अभी भी यह डाउनलोड करने के लिए 39.3 एमबी अपडेट दिखा रहा है और यह बार-बार विफल हो रहा है। हर बार जब मैंने इन 39.3 एमबी अपडेट को स्थापित करने की कोशिश की, तो यह दिखाता है कि, यह इंटरनेट से कनेक्ट नहीं हो सकता है, लेकिन मेरे कनेक्शन के साथ कोई समस्या नहीं है (नेटवर्क संकेतक यह जुड़ा हुआ है और मैं ब्राउज़ कर सकता हूं और कुछ भी डाउनलोड कर सकता हूं)। यह मुझे निम्नलिखित संदेश दे रहा है:

Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch
Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-headers-3.2.0-43-generic-pae_3.2.0-43.68_i386.deb Size mismatch

मुझे लगा कि यह सूत्रों की सूची में एक समस्या है। इसलिए मैंने निम्नलिखित कमांड दी है

sudo rm -vf /var/lib/apt/lists/partial/*

पहले, मैंने एक अलग कंप्यूटर के साथ इसी प्रकार की समस्या का सामना किया है। उस समय, इस समाधान ने मेरे लिए काम किया, लेकिन अब मैं इस समस्या का सामना कर रहा हूं। इस समस्या को हल करने के लिए कोई भी मेरी मदद करें।

अपडेट करें

E: GPG error: http://us.archive.ubuntu.com precise-backports Release: The following signatures were invalid: NODATA 2

अब मुझे GPG त्रुटि का सामना करना पड़ रहा था। इसे हल करने के लिए मैंने निम्नलिखित प्रयास किया

$ sudo -i
# apt-get clean
# cd /var/lib/apt
# mv lists lists.old
# mkdir -p lists/partial
# apt-get clean
# apt-get update
# exit

इस कमांड के बाद। मैंने अंतिम आदेशों को दर्ज किया।

sudo apt-get dist-upgrade

Answer 2

बस कुछ नए 12.04.5 इंस्टाल पर यूएस आर्काइव पैकेज सूची हैश सम मिसमैच था। कम से कम मेरे लिए काम करने वाला छोटा समाधान:

# rm /var/lib/apt/lists/partial/us.archive.ubuntu.com_ubuntu_dists_precise_*
# rm /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_precise*
# aptitude update
... now worked ...
