jb完後 cydia跑更新出現錯誤!!

[vgvgvg12321]

請問一下 我jb完之後 進去cydia跑更新 結果他出現這三段紅字!

⊕Sub-process/bin/bzip2 returned an error code(2)

! Failed to fetch
http://cydia.zodttd.com/repo/cydia/d...m/Packages.bz2 Sub-process"cydia.zodttd.com/repo/cydia/dists/stable/main/binary-iphoneos-arm/Packages.bz2 Sub-process[/URL]/bin/bzip2 returned an error code(2)

⊕Some index files failed to download,they have been ignored,or old ones used instead


請問是有資料跑掉嗎?還是沒關係? 現在進去cydia抓程式事都沒問題 但是我怕對以後有影響！請達人幫我解答 謝謝
