[Bug 1956039] Re: BADSIG 871920D1991BC93C Ubuntu Archive Automatic Signing Key (2018) <ftpmaster at ubuntu.com>

[Heinrich Schuchardt]

This is what resolved the problem for me:

$ sudo -s
# apt-get clean
# cd /var/lib/apt
# mv lists lists.old
# mkdir -p lists/partial
# apt-get clean
# apt-get update
