Finalmente encontré la solución, gracias a lo que encontré en esta respuesta al mismo problema en askubuntu:
<a href="https://askubuntu.com/questions/1120363/mysql-ppa-invalid-signature" rel="nofollow" target="_blank">https://askubuntu.com/questions/1120363/mysql-ppa-invalid-signature</a>
Abriendo la terminal (Ctrl+Alt+T) e ingresando uno los siguientes comandos:
<blockquote>sudo apt-key list</blockquote>
Con este comando verifiqué que la firma había caducado:
<blockquote>pub dsa1024 2003-02-03 [SCA] [caducó: 2019-02-17]
A4A9 4068 76FC BD3C 4567 70C8 8C71 8D3B 5072 E1F5
uid [ <b>caducada</b> ] MySQL Release Engineering <mysql-build oss.oracle.com=""></mysql-build></blockquote>
Luego apliqué el comando:
<blockquote>sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 8C718D3B5072E1F5</blockquote>
<b>8C718D3B5072E1F5</b> es la clave que se indica en el error del update.
finalmente al ejecutar otra vez el comando <blockquote><b>sudo apt-get update</b></blockquote> fue todo un éxito.

1. Cerrar la aplicación VirtualBox<br />
2. Ir a la línea de comandos y ejecutar:
<br />
<blockquote>
VBoxManage modifyvm osx --cpus 1
VBoxManage modifyvm osx --vram 128
VBoxManage setextradata osx VBoxInternal2/EfiGopMode 5
<br />
VBoxManage setextradata osx "VBoxInternal2/SmcDeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"</blockquote>
Atención:<br />
* cada comando es línea a línea.<br />
* reemplazar osx por el nombre dado a la máquina virtual. <br />
<br />
3. Abrir VirtualBox y Ejecutar la máquina virtual<br />
4. Montar la imágen iso del sistema operativo OSX e instalar.<br />
5. Luego de aproximadamente 30 minutos el sistema se reiniciará y quedará listo para su uso.<br />

<br />
Cell phone model: BLU Star JR<br />
Vendor ID 1782<br />
Recognized in the Linux OS as <b>Spreadtrum</b> Communications Inc.<br />
<br />
I added this universal rule in the <code>/etc/udev/rules.d/51-android.rule</code><br />
<blockquote class="tr_bq">
<pre class="default prettyprint prettyprinted"><code><span class="pln">ACTION</span><span class="pun">==</span><span class="str">"add"</span><span class="pun">,</span><span class="pln"> SUBSYSTEM</span><span class="pun">==</span><span class="str">"usb"</span><span class="pun">,</span><span class="pln"> ENV</span><span class="pun">{</span><span class="pln">DEVTYPE</span><span class="pun">}==</span><span class="str">"usb_device"</span><span class="pun">,</span><span class="pln"> ENV</span><span class="pun">{</span><span class="pln">ID_USB_INTERFACES</span><span class="pun">}==</span><span class="str">"*:ff420?:*"</span><span class="pun">,</span><span class="pln"> MODE</span><span class="pun">=</span><span class="str">"0666"</span></code></pre>
</blockquote>
And manually added the Vendor ID (1782) to the ~/.android/adb_usb.ini file <br />
<blockquote class="tr_bq">
<pre class="default prettyprint prettyprinted"><code><span class="com"># ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.</span><span class="pln">

Reconnect the device and verify thet my device is connected with <br />

Luego de ingresar al sistema operativo el menú de aplicaciones no aparece.<br />
<br />
La solución:<br />
Creé un pequeño script eliminando una referencia a lago llamado slingshot<br />
<br />
<blockquote class="tr_bq">
#!/bin/bash<br />
# solution to show applications menu when it's hiding in elementary OS<br />
pkill slingshot </blockquote>
<br />
luego le dí las propiedades ejecutables para ejecutarlo cada vez que se presente el inconveniente y hasta que una nueva distro solucione este bug.<br />
<br />
<blockquote class="tr_bq">
<tt>chmod ugo+x filename </tt></blockquote>
