@krlmlr Hey!
Please fix the test after #1570.
(I wasn't aware that the long-standing sql internal functions had been removed.)

duckdb-r/tests/testthat/test-duckdb-extensions.R

Line 5 in 8649e01

expect_no_error(sql("INSTALL icu"))

Unless this test is fixed, it will continue to fail on the R-multiverse.

I tried installing a few extensions, works for me.
