I was following the instructions on here https://www.digitalocean.com/community/tutorials/how-to-upgrade-to-ubuntu-16-04-lts but every time I do sudo apt-get update
, I run into a message that ends with
100% [1 Packages bzip2 0 B] [27 InRelease gpgv 1,855 B] [Waiting for headers] [Waiting for headers] [Waiting for headers]
[WaSplitting up /var/lib/apt/lists/partial/packages.ubuntu.com_xenial_libpcre2-dev_dists_wily_InRelease
into data and signature faIgn http://packages.ubuntu.com wily InRelease
E: GPG error: http://packages.ubuntu.com wily InRelease: Clearsigned file isn't valid, got 'NODATA' (does the network require authentication?)
I think this means that there's something up with my libpcre2, which I remember I had to install in a really hacky way that I can't remember any of the details from. But in any case I can't seem to get my apt-get to detect that 16.04 exists. How can I get apt-get update to ignore my libpcre2 or uninstall it so I can reinstall it when the upgrade to 16.04 is complete?
