Congrats for a good working system. Lenovo professional range laptops are usually working quite well with Linux, just use recent enough Linux version.

Wild guess. Libspa version has changed and thus its path too. You will have to put (probsbly new version) of aac.so file to new libspa directory.
Yeah, it might require new one if dependencies have been changed.
Note. Before rebooting, regenerate initramfs for all kernel versions. I am not in debian, but dpkg-reconfigure initramfs-tools might do it.
What filesystem is in use where lotro files are stored?
I am a Finn. How I can tell if I am delightfully or some other way weird?
Here I take micro-retirement of 4 weeks every summer, plus one week in wintertime.
Vim + vimwiki is what I use, with session saving plugin. That is all I need. For syncing, I use either git or syncthing.
I think their vision is solid. I just think there are gaps in following their vision. Wheres the “create new empty file”? Where’s the “open folder in terminal”? Why do I need to install bunch of bloatware to change more than 2 options?
On my Gnome Files, there is option to "Open in terminal" and create new files (from templates, which were set up by default on my distro). All by default without any extensions or anything.
If computers are in same network, even with different ip addresses, they still can see all broadcast and multicast traffic. This means for example dhcp.
If you fully trust your computers, and are sure that no external party can access any of them, you should be fine. But if anyone can gain access to any of your computers, it is trivial to gain access and sniff traffic in all networks.
If you need best security, multiple switches and multiple nics are unfortunately only really secure solution.
Luks FDE, and install dropbear-initramfs, configure ssh authorized_keys and rebuild initramfs. Then you can access initramfs via ssh to type luks password.
If you just rename the dir, and then find all broken symlinks in your system?
find . -xtype l
Excellent news.
