Ubuntu 開發中版本上面的套件大多是來是 Debian testing/unstable 的自動同步，不過等到 DebianImportFreeze 之後跟 FeatureFreeze 之前，如果還有新版本的套件在 Debian testing/unstable 上面出現時，就要透過 SyncRequestProcess 來要求 Ubuntu 開發中版本同步 Debian 上面的套件，FeatureFreeze 之後就不能再要求同步套件了，只能夠修正程式的錯誤。
以下示範三種情況。
狀況一： Ubuntu 開發中版本的套件並沒有包含 Ubuntu 社群的錯誤修正
使用 ubuntu-dev-tools 套件底下的 requestsync 指令
$ requestsync -C -d unstable --lp betaradio precise
然後會看到以下內容：
Summary (one line): Sync betaradio 1.4-1 (universe) from Debian unstable (main) Description: Please sync betaradio 1.4-1 (universe) from Debian unstable (main) Changelog entries since current precise version 1.3-1: XXX FIXME: add changelog here XXX
要將最後一行改掉，加上 Debian testing/unstable 套件裡面的訊息，所以就變成了：
Summary (one line):
Sync betaradio 1.4-1 (universe) from Debian unstable (main)
Description:
Please sync betaradio 1.4-1 (universe) from Debian unstable (main)
Changelog entries since current precise version 1.3-1:
betaradio (1.4-1) unstable; urgency=low
* New upstream release.
* debian/patches/00_dont_install_header: Don't install header file into the
system.
-- Shih-Yuan Lee (FourDollars) <fourdollars[at]gmail.com> Sat, 14 Jan 2012 20:58:32 +0800
最後就會產生一個 Launchpad Bug 像是 Bug #918059 in betaradio (Ubuntu): “Sync betaradio 1.4-1 (universe) from Debian unstable (main)” 這樣就做好了，之後就是去注意這個 Bug 的變化，適時的去回應 Ubuntu Developer 提出的問題(如果有的話)。
狀況二： Ubuntu 開發中版本的套件已經有包含了一些 Ubuntu 社群的錯誤修正
在這種情況底下 Ubuntu 不會自動去同步 Debian testing/unstable 上面的套件，以防有些 Ubuntu 社群所做的錯誤修正遺失。
使用跟上面一樣的指令：
$ requestsync -C -d unstable --lp ibus-chewing precise
然後會看到以下內容：
Summary: Sync ibus-chewing 1.3.10+clean-1 (main) from Debian unstable (main)
Description:
Please sync ibus-chewing 1.3.10+clean-1 (main) from Debian unstable (main)
Explanation of the Ubuntu delta and why it can be dropped:
* debian/patches/IBusChewingEngine-def-fix-SIGSEGV-on-preference-save.patch:
Fix misuse of g_value_get_gtype in g_value_to_g_variant. (LP: #874028)
* debian/patches/escape-to-close-candidate-window-on-plain-
zhuyin.patch: Fix plain zhuyin with space as selection problem.
(https://github.com/definite/ibus-chewing/pull/8/) (LP: #843619)
[這邊有一行我忘了原本寫些什麼了，總之要你改掉寫上你的解釋]
Changelog entries since current precise version 1.3.9.2-3ubuntu2:
XXX FIXME: add changelog here XXX
跟前面一樣加上 Debian testing/unstable 套件裡面的訊息，還有解釋一下為什麼 Ubuntu 社群的錯誤修正都被拿掉了，然後就變成了：
Please sync ibus-chewing 1.3.10+clean-1 (main) from Debian unstable (main)
Explanation of the Ubuntu delta and why it can be dropped:
* debian/patches/IBusChewingEngine-def-fix-SIGSEGV-on-preference-save.patch:
Fix misuse of g_value_get_gtype in g_value_to_g_variant. (LP: #874028)
* debian/patches/escape-to-close-candidate-window-on-plain-
zhuyin.patch: Fix plain zhuyin with space as selection problem.
(https://github.com/definite/ibus-chewing/pull/8/) (LP: #843619)
These patches are already included in ibus-chewing 1.3.10+clean-1.
Changelog entries since current precise version 1.3.9.2-3ubuntu2:
ibus-chewing (1.3.10+clean-1) unstable; urgency=low
* New upstream release.
* All Debian patcheds dropped.
* Add Osamu as uploaders.
* Repackaged upstream tar with normal tar and removing .swo
-- Osamu Aoki <osamu[at]debian.org> Mon, 26 Dec 2011 00:17:58 +0900
最後就會產生一個 Launchpad Bug 像是 Bug #918061 in ibus-chewing (Ubuntu): “Sync ibus-chewing 1.3.10+clean-1 (main) from Debian unstable (main)” ，之後就是去注意這個 Bug 的變化，適時的去回應 Ubuntu Developer 提出的問題(如果有的話)。
狀況三： Ubuntu 開發中版本並沒有包含這個套件
在這種情況下應該是最單純的，應該不會有額外的動作要做，都是按下 Enter 就可以做到完。
使用跟上面一樣的指令：
$ requestsync -C -d unstable --lp hime precise
然後會看到以下內容：
'hime' doesn't exist in 'Ubuntu precise'. Do you want to sync a new package? Press [Enter] to continue or [Ctrl-C] to abort.
當然是按下 Enter 到下一步
Your sync request shall require an approval by a member of the appropriate sponsorship team, who shall be subscribed to this bug report. This must be done before it can be processed by a member of the Ubuntu Archive team. If the above is correct please press [Enter]
再按下 Enter 到下一步
Currently the report looks as follows: Summary (one line): Sync hime 0.9.9-1 (universe) from Debian unstable (main) Description: Please sync hime 0.9.9-1 (universe) from Debian unstable (main) All changelog entries: hime (0.9.9-1) unstable; urgency=low * Initial release (Closes: #652022) -- Yao Wei (魏銘廷) <mwei[at]lxde.org> Sat, 14 Jan 2012 00:24:08 +0800 Do you want to edit the report [y/N]?並沒有修改的必要，所以還是按下 Enter 到下一步
The final report is: Summary: Sync hime 0.9.9-1 (universe) from Debian unstable (main) Description: Please sync hime 0.9.9-1 (universe) from Debian unstable (main) All changelog entries: hime (0.9.9-1) unstable; urgency=low * Initial release (Closes: #652022) -- Yao Wei (魏銘廷) <mwei[at]lxde.org> Sat, 14 Jan 2012 00:24:08 +0800 Press [Enter] to continue or [Ctrl-C] to abort.最後的確認，還是按下 Enter 於是就會產生一個 Launchpad Bug 像是 Bug #923637 in Ubuntu: “Sync hime 0.9.9-1 (universe) from Debian unstable (main)”，之後就是去注意這個 Bug 的變化，適時的去回應 Ubuntu Developer 提出的問題(如果有的話)。
