I used "sudo snap install bitcoin-core" and it appeared to install fine except I get the error: "Failed to launch 'Bitcoin Core' Desktop file didn't specify Exec Field." Did I do something wrong? Maybe I am not finished with the install?
This is nearly a pristine installation of Ubuntu. The only other thing I did was run updates and I installed Konsole prior to installing Bitcoin Core. I ran the "sudo snap install..." command from Konsole.
Thanks to all.
