Perhaps something more than speculation.
I’ll drop this here for consideration;
As it seems like your NordVPN came from the AUR, this mention of libxml2
indeed seems related.
Updating that file likely solved your initial problem, and will do the same for other packages that might still depend on the older libxml2
version.
This is of course only conjecture, as I haven’t looked much beyond the brief mention, and I don’t use NordVPN.
- libxml2-legacy 2.13.8-1 (AUR)
