Assumpte: [DNG] Ascii to Beowulf upgrade borked with eudev
G'day all,

I use a self-compiled kernel (v5.10) at the moment.
An Ascii to Beowulf upgrade died early on because the eudev preinst script isn't correctly parsing /proc/kallsyms.

Preparing to unpack .../25-eudev_3.2.9-8~beowulf1_amd64.deb ...
Since release 198, udev requires support for the following features in
the running kernel:

- inotify(2)            (CONFIG_INOTIFY_USER)
- signalfd(2)           (CONFIG_SIGNALFD)
- accept4(2)
- open_by_handle_at(2)  (CONFIG_FHANDLE)
- timerfd_create(2)     (CONFIG_TIMERFD)
- epoll_create(2)       (CONFIG_EPOLL)
dpkg: error processing archive /tmp/apt-dpkg-install-PJCPSM/25-eudev_3.2.9-8~beowulf1_amd64.deb (--unpack):
  new eudev package pre-installation script subprocess returned error exit status 1

I unpacked, patched out the check and re-packed the deb, then manually installed it.
Unfortunately for me (yay) the upgrade then proceeded to break horribly with an apt-get -f install resulting it in wanting to uninstall X and everything associated with it, requiring severe manual intervention to get a functioning system again.

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cups-daemon : Depends: libcups2 (= 2.2.10-6+deb10u4) but 2.2.1-8+deb9u6 is installed
cups-ipp-utils : Depends: libcups2 (= 2.2.10-6+deb10u4) but 2.2.1-8+deb9u6 is installed
libcupsimage2 : Depends: libcups2 (= 2.2.10-6+deb10u4) but 2.2.1-8+deb9u6 is installed
libeudev-dev : Depends: libeudev1 (= 3.2.2-13) but 3.2.9-8~beowulf1 is installed
libreoffice-java-common : Depends: libreoffice-common (= 1:6.1.5-3+deb10u7) but 1:5.2.7-1+deb9u11 is installed

python3-lib2to3 : Depends: python3 (>= 3.7.1-1~) but 3.5.3-1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

I got there, but there was a lot of manual dpkg -i from the cache directory to get things back on track.

Just a headsup.
