Comment 4 for bug 188797

Apologies -- I had replied to your question via email thinking that it would be reflected back onto the forum, but clearly it is a one-way street from forum to email but not the other way (no doubt this is documented somewhere had I thought to check).

Ah, so there is more logging I could have use to troubleshoot the problem
myself. See attached for a tarball containing all files in that directory. A
quick grep turned up:

# grep -i error /var/log/dist-upgrade/*
/var/log/dist-upgrade/apt.log:Installing libgpg-error0 as dep of libxslt1.1
