It's not « Nexus 5 » specific issue. Looking official android sdk documentation: ( https://developer.android.com/tools/help/adb.html#Enabling ) quote: ---- Note: When you connect a device running Android 4.2.2 or higher to your computer, the system shows a dialog asking whether to accept an RSA key that allows debugging through this computer. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog. This requires that you have adb version 1.0.31 (available with SDK Platform-tools r16.0.1 and higher) in order to debug on a device running Android 4.2.2 or higher. ----
And obviously, android 5.+/5.1.1 seem to need this 1.0.32 version of adb. I've an android 5.1.1, and need adb 1.0.32 to show my device (not a nexus) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to android-tools in Ubuntu. https://bugs.launchpad.net/bugs/1402195 Title: Newer version of adb needed for nexus 5 Status in android-tools package in Ubuntu: Triaged Status in android-tools source package in Vivid: Won't Fix Status in android-tools package in Debian: Fix Released Bug description: When adb sideloading 5.0.0 -> 5.0.1, the recovery on a nexus 5 requires at least adb 1.0.32 $ adb version Android Debug Bridge version 1.0.31 :( ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: android-tools-adb 4.2.2+git20130218-3ubuntu36 ProcVersionSignature: Ubuntu 3.16.0-25.33-generic 3.16.7 Uname: Linux 3.16.0-25-generic x86_64 NonfreeKernelModules: zfs zunicode zavl zcommon znvpair ApportVersion: 2.14.7-0ubuntu8 Architecture: amd64 CurrentDesktop: Unity Date: Sat Dec 13 14:47:38 2014 InstallationDate: Installed on 2014-02-07 (308 days ago) InstallationMedia: Ubuntu 13.10 "Saucy Salamander" - Release amd64 (20131016.1) SourcePackage: android-tools UpgradeStatus: Upgraded to utopic on 2014-11-08 (34 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/android-tools/+bug/1402195/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
