Blueman：RecentConns "NoneType"オブジェクトは反復可能ではありません。

Manjaroの最後のアップデートでは、何らかの理由でブルーマンを有効にすることはできません。エラーは次のとおりです。

Exception occurred org.bluez.Error.Blocked: Blocked through rfkill

gnome-themes-standardがインストールされました。

彼らは私のチケットをgithubにバグとしてマークし、私は決して答えを受け取らず、それを修正するには、次のバージョンのbluemanまで待つ必要があるようです。とても長く待っています。 xfceで利用可能な他のBluetoothアプレットはありますか？

答え1

Lynobの回答の小さなアップデート：同じ問題が発生し、blueman-applet少なくともv.1.99で同じバグが見つかりましたが、問題となるコードは87〜88/usr/lib/python2.7/dist-packages/blueman/main/KillSwitchNG.py行にあります。

フラグ |= os.O_NONBLOCK
self.fd = os.open("/dev/rfkill", フラグ)
...

問題を解決するには、呼び出す前に次の行を追加して設定する必要がありますbinary mode。flagsopen(...)

フラグ|= os.O_BINARY

答え2

私は走った

sudo rfkill unblock bluetooth

私はうまくいくようですが、githubでChristopher Schrammが私のチケットを再び開き、まだバグとしてマークされています。おそらく彼は私が知らないバグ、おそらくGTKのバグを調べているようです。私にとって私が興味を持っているのは、それがうまくいくということです。

編集する

Christopherが実際のバグを見つけました。blueman/plugins/mechanism/RfKill.pyそれに応じてファイルを確認して変更するか、更新がプッシュされるのを待ちます。 15行目は次のようになります

f = open('/dev/rfkill', 'wb')ちょうどbを追加してください
