Failed to open release log (could not open file ‘/home/user/VirtualBox VMs/sol/Logs/VBox.log’ (fOpen=0x322), VERR_FILE_NOT_FOUND).

Failed
to open release log (could not open file ‘/home/user/VirtualBox VMs/sol/Logs/VBox.log’
(fOpen=0x322), VERR_FILE_NOT_FOUND).

To fix the problem:

root@user:/home/user# cp .VirtualBox/VirtualBox.xml-prev .VirtualBox/VirtualBox.xml

Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode.

I got this error message during reconfiguration of cisco switch 3560G series.
Before configure a “trunk” mode we have to configure encapsulation.

to solve the problem

(config-if)#switchport trunk encapsulation dot1q
(config-if)#switchport mode trunk

now, everything is good, we can add vlans in this way

(config-if)#switchport trunk allowed vlan add 10

%SW_VLAN-4-VLAN_CREATE_FAIL: Failed to create VLANs 3310: extended VLAN(s) not allowed in current VTP mode% Failed to create VLANs 3310 Extended VLAN(s) not allowed in current VTP mode. %Failed to commit extended VLAN(s) changes.

(config)#do sh vtp status

I will not use a VTP protocol.
In my case I can stopped it.

(config)#vtp mode off
