Seems like thunderbird needs a rebuild to match current library versions:
pacman -S thunderbird
resolving dependencies...
warning: cannot resolve "libicui18n.so=67-32", a dependency of "thunderbird"
warning: cannot resolve "libicuuc.so=67-32", a dependency of "thunderbird"
:: The following package cannot be upgraded due to unresolvable dependencies:
thunderbird
Any idea when this could happen?
Thanks!
