Arcanist seems to crash with any invocation, possibly due to an incompatibility with the system PHP (the package says it depends on either php-blah or php5-blah (php5 packages aren't in the core package repo any more anyway), I have the php package installed, which is version 8.1)?
Upstream arcanist (e50d1bc4eabac9c37e3220e9f3fb8e37ae20b957) does not have this issue.
Steps to reproduce:
1. `apt install arcanist`
2. `arc help`
3. Observe crash
Workaround for users:
Install arcanist from upstream following these instructions: https://secure.phabricator.com/book/phabricator/article/arcanist_quick_start/
Suggested fix for the package maintainers:
Update the arcanist package or provide packages for an older PHP runtime and depend on that.
Here's the crash message:
