How to Check What DNS Servers Currently Used In Ubuntu
I used to ask myself the same question on how to check what DNS servers are currently being used whether it is manually or dynamically (via DHCP) configured.
For manually configured DNS Server(s):
more /etc/resolv.conf
For manually or dynamically configured DNS Server(s) :
more /etc/resolv.conf
OR
systemd-resolve --status

Failed to install electerm using snap on Ubuntu
After I download the snap file "electerm-1.3.1-linux-amd64.snap" from this url, I get the following error shown in the snapshot below using command:
sudo snap install electerm-1.3.1-linux-amd64.snap
To fix such an error, the option --dangerous is used to force the command not to verify the installation signature:
sudo snap install --dangerous electerm-1.3.1-linux-amd64.snap
In summary, to resolve the error "cannot find signatures with metadata for snap" when installing using snap, you can use the flag --dangerous

***Note***: I encounter one problem; it is unable to use the command "sudo", and other commands as shown in below snapshot when using in electerm with error permission denied:
So I decide to uninstall with the following command:
sudo snap remove electerm
Once I download deb package from this link, I simply install it by the following command:
sudo dpkg -i electerm-1.3.4-linux-amd64.deb
Then the problem of "permission denied" is gone, and I can normally use all the commands:
As of March 24, 2020, the version electerm-1.3.4-linux-amd64.deb is available for download from this link
sudo snap install electerm-1.3.1-linux-amd64.snap

Openshot cannot be started in Ubuntu 18.04
After I install openshot via PPA, following from its official website:
sudo add-apt-repository ppa:openshot.developers/ppa
sudo apt-get update
sudo apt-get install openshot-qt
I cannot start openshot. After googling I found the solution by removing python3 module pyqt5 as follows:
$pip3 uninstall pyqt5
