Oh, you may also want to try moving lists/ out of the way and running apt update again.
And perhaps send me a tarball of /var/lib/apt and /etc/apt - then I might have luck reproducing it. If you want to, you could try bisecting this in the apt git repo, starting with git bisect start git bisect good 1.2.12 git bisect bad 1.2.15 git bisect run sh ./script.sh where script.sh is: #!/bin/sh make fast || exit 125 sudo LD_LIBRARY_PATH=$PWD/build/bin/ ./build/bin/apt-get update -o Dir::Bin::Methods="$PWD/build/bin/methods/" 2>&1 | tee update.log if grep "was encountered" update.log; then exit 1 fi exit 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1642386 Title: At least one invalid signature was encountered.
