Hi. This problem happened a LOT when my Tower & Lappy still ran Mint 17.x KDE4, but this morning is the first time it's happened to me in Maui. Bummer.
Symptom 1: Launch Update Manager & attempt to update package(s) when indicated. Enter normal password when prompted. Password dialog closes, U/M is again focused, but nothing further occurs [ie, no updates proceed].
Symptom 2: Attempt to launch Synaptic from Application Menu. Enter normal password when prompted. Password dialog closes, but Synaptic never appears.
Symptom 3: Attempt to launch Synaptic in cli, get msg: "Trace/breakpoint trap".
Symptom 4: Attempt to run "sudo dpkg --configure -a" in cli; nothing happens except cursor moves to new line with normal SOE prompt (ie, just as if the previous line entry had never occurred].
Unexpectedly, using 2 of the available updates i'd noticed at #1 above as test-case, running "Z97-HD3:~$ sudo apt-get install libxnvctrl0 nvidia-settings" in cli worked perfectly. So why is my sudo password accepted & acted-upon here, but not in the above cases?
Back in Mint, 100% of the time that this problem arose, i noticed that /tmp/kde-moi had LOST its usually-present file "xauth-1000-_0". However this morning in Maui, that file still exists. In Mint, 100% of the time this problem arose, the only solution was to reboot. Once i post this new topic i shall reboot Maui, & hope that also fixes it... but the central question remains; WHY does this occur & HOW can i solve it permanently so no more reboots are needed for it?
