I have an iPhone 6 jailbroken on iOS 8.3 using the Taig 2.1.3. Everything I go into Cydia it always says there is an upgrade to TaiG 8.1.3-8.x untether and TaiG uncache (Obsolete). But everything I try to update it, it always fails and gives two errors "installing taigunether83x would break existing software" and "Sub-process /usr/bin/dpkg returned an error code (1)" and asks to restring. When I go back to it, it is always there. When I check in installed items though the TaiG is already version 2.1.3. I had this same error when I used the TaiG 2.0.0 and just updated it through the deb file. So I did a fresh restore of iOS 8 through iTunes and jailbroke using 2.1.3 but it still gives the same error. All the tweaks and jailbreak apps are working fine though. But everytime I open Cydia, it always says I have 2 Essential Upgrades but when I try to upgrade them they always fail. Is anyone else having this problem?
