[Solved] Dependency conflict between icu and thunderbird

As of today I cannot update Arch:

```
~ sudo pacman -Syu
:: Synchronizing package databases...
core is up to date
extra is up to date
multilib is up to date
:: Starting full system upgrade...
resolving dependencies...
looking for conflicting packages...
error: failed to prepare transaction (could not satisfy dependencies)
:: installing icu (73.2-1) breaks dependency 'libicuuc.so=72-64' required by gspell
:: installing icu (73.2-1) breaks dependency 'libicuuc.so=72-64' required by harfbuzz-icu
:: installing icu (73.2-1) breaks dependency 'libicuuc.so=72-64' required by raptor
:: installing icu (73.2-1) breaks dependency 'libicui18n.so=72-64' required by thunderbird
:: installing icu (73.2-1) breaks dependency 'libicuuc.so=72-64' required by thunderbird
```

Can anyone suggest a fix?

EDIT:
the conflict is real, thunderbird and the other packages list icu v72 as a dependency but the Arch repos want to update it to v73. Is this a bug in the Arch repos? Or am I the only one seeing this for some reason?

Re: [Solved] Dependency conflict between icu and thunderbird

Your system's primary mirror is missing the icu 73.2 rebuild of thunderbird (102.12.0-2).  Either change the system's primary mirror or wait for extra on that mirror to resync.

Re: [Solved] Dependency conflict between icu and thunderbird

Thanks loqs!

Is the primary mirror the first one listed in /etc/pacman.d/mirrorlist? Or how do I find out what my primary mirror is and what would be a better mirror?

Isn't it still weird that the mirror is proposing what amounts to a partial update? Feels like this should never happen.

Yes

I can only suggest Mirrors#Sorting_mirrors

Isn't it still weird that the mirror is proposing what amounts to a partial update? Feels like this should never happen.

I think this is a known bug/limitation in determining a mirror's status.

Thank you loqs, changing the primary mirror did the job
