यदि आप डरते नहीं हैं कि आपके हाथ गंदे हैं, तो ऐसा करने का सबसे अच्छा तरीका है:
apt-cache शो पैकेजेन
यह आपको आपके सोर्स के अनुसार पैकेज के सभी विभिन्न संस्करण दिखाएगा। आपको कुछ ऐसा मिलेगा (यह मेरे लिए कैसा है):

Description: PulseAudio client libraries (zeroconf support)
PulseAudio, previously known as Polypaudio, is a sound server for POSIX and
WIN32 systems. It is a drop in replacement for the ESD sound server with
much better latency, mixing/re-sampling quality and overall architecture.
.
Client libraries used by applications that access a PulseAudio sound server
via PulseAudio's native interface.
.
This package adds support for zeroconf (aka. Avahi, mdns) discovery of
PulseAudio sinks and sources by client applications.

बस आपके लिए उपलब्ध विभिन्न संस्करण की जांच करें, और फिर करें:
apt-get install packagname=version
ऊपर दिए गए आउटपुट के उदाहरण के रूप में फिर से:
apt-get install ibpulse-browse0=1:0.9.14-0ubuntu20
जैसा कि आप देख सकते हैं कि मेरा pulseaudio लॉन्चपैड पर एक ppa से है तो अगर मैं jaunty द्वारा आपूर्ति की गई मूल एक पर वापस जाना / वापस करना चाहता था, तो मैं ऊपर उल्लिखित सभी pulseaudio पैकेजों के साथ करूँगा जो मैंने स्थापित किए थे।
apt-cache policy <packagename>
, जो आपको केवल उपलब्ध संस्करणों और उनके स्रोतों को दिखाएगा, इसलिए आपको उन सभी अतिरिक्त सामानों के बजाय आपको आवश्यक जानकारी मिलती है जो आपकोapt-cache show
प्रदान करता है।
