I am attempting a new install of Ubuntu Studio 21.04 on a Samsung Series 5 Ultra Laptop (Intel Core i5, 8 GB ram, 500 GB hard drive). It has proper access to the internet via Wifi. Everything proceeds properly until it is in the step labelled "Contextual Processess Job" at 78% and it fails with the following error:
Installation Failed. External command failed to finish. Command apt install -y -no-upgrade -o Aquire:: gpgv:Options::=ignore-time- conflict shim-signed failed in 300 seconds There was no output from the command
I have confirmed the validity of the downloaded iso using SHA256. and tried the install several times with the same error.
Any suggestions?
Thanks... Tom.
