Comment 1 for bug 1963719

Without this fix, pagekite frontends are completely broken (unable to accept incoming connections) due to Python 3 incompatibilities: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1006534

The new version in Debian only contains a single 3-line fix for this issue: https://salsa.debian.org/freedombox-team/pagekite/-/commit/ebd88901ee139044babed2b87962247a2d938570
