The following software installed, but with some caveats:
Dropbox: downloaded .deb, installed with Software Install. Installing Dropbox has always been somewhat touch and go, but I have always gotten it installed and running. When you first run Dropbox it runs another installer and warns that your system does not have python-gpgme installed and it can not verify your download. When I was running 17.10 I simply installed python-gpgme from the terminal and Robert is your father's brother. When I ran sudo apt-get install python-gpgme on 18.04 I received the following error message: "E: Package 'python-gpgme' has no installation candidate". I went ahead with the install anyway and everything is working fine.
Google Chrome: downloaded .deb, installed with Software Install. Chrome installed fine, but it did sign me out of my account twice in about an hour. This could simply be a problem with Google that coincided with my installation on Ubuntu 18.04 so I will have to see if the problem persists. There is a small UI problem that was not visible in 17.10 related to the min/max/close buttons, but it is not horrible and I assume it will be ironed out.
HandBrake: I entered the following commands to install HandBrake (and get it to rip DVDs): sudo apt-get install ubuntu-restricted-extras sudo apt-get install libdvd-pkg sudo dpkg-reconfigure libdvd-pkg sudo apt-get install handbrake
This worked flawlessly (which is more than I can say when I tried the same on 17.10, although I did get it working),
VLC: the VLC repoository would not work with Bionic Beaver as it is "not secure" which meant I had to install the snap. The snap version would not play DVDs. Next I installed VLC from the Ubuntu Software app, and I deleted ~/.dvdcss as suggested here. DVDs are now playing, but the quality is not good. As I almost never watch DVDs on the computer it is not something I am concerned about. Incidentally, GNOME Videos that comes pre-installed with Ubuntu 18.04 would still not play DVDs. I removed it.
Visual Studio Code: downloaded the .deb, ran the following commands: sudo dpkg -i <file>.deb sudo apt-get install -f
The app works fine, but I received the following message in the terminal during installation: "WARNING: unsafe ownership on homedir '.gnupg'". I fired up The Googles and found that my .gnupg directory's permissions are indeed correct. Someone suggested that it may have been due to using the sudo command...I have no idea if this is the case.
The following software would not install:
pyRenamer: sudo apt-get install pyrenamer responds with "E: Unable to locate package pyrenamer" I am hoping the maintainer of this package gets one packaged up for Bionic as it was my favorite bulk file renamer for Linux.
RealVNC Connect: unfortunately, this was already broken in 17.10. RealVNC support sent me a suggested solution, but it did not work. There are issues with administrative privileges that need to be granted during the installation. Hopefully they will get this taken care of sooner rather than later. I use the RealVNC Viewer app on my Linux laptop and iPhone to connect to my Mac Mini. I would like to use my iPhone to connect to my Linux laptop as well.
