chromium on Ubuntu Focal does not fully install

[schloerke]

When testing chromium on Focal within Docker files in https://github.com/rstudio/shinyapps-package-dependencies/pull/302/files#diff-7f5883cd386273c8ef28afb6578002cdc0d27816af32fc681e31178c1137e8e5 , When executed, chromium requests to be installed using snap install chromium even though the standard apt-get install chromium-browser seems to work.

snap installations have difficulty on docker files (link to similar error output that I was seeing).

I don't know if we should use the instructions that I was able to achieve in https://github.com/rstudio/shinyapps-package-dependencies/pull/302/files#diff-7f5883cd386273c8ef28afb6578002cdc0d27816af32fc681e31178c1137e8e5R27-R56 , or say that it can not be installed on Focal.

If r-system-requirements is already using snap, then I believe it could solved using a post_install hook.

There aren't any packages on CRAN that have Chromium in SystemRequirements today, and I believe Chromium was originally added for Chromote (#48, but @colearendt could confirm). If we add Chrome in #87, could we just remove the Chromium rule? It feels redundant to have both Chrome and Chromium when packages only need one of them, and Chrome looks easier to install.

[colearendt]

Yes, that was for chromote IIRC, paired with this PR: rstudio/chromote#14 . I think there are a few other packages that use Chrom*.

I suspect the new rule will cover these:

• https://github.com/hrbrmstr/decapitated/blob/205babc38974323d96291f05f99b49f9aac9a6e2/DESCRIPTION#L18

Cool! I'll drop #88 in favor of removing the rule entirely.
