errors installing on linux-ubuntu

[HomeStayMom]

Dear Sir,
I am truly enjoying your package and love it.
Recently I tried to install on my Ubuntu and run in some issues.
Unfortunately my effort installing in base R from Cran with all dependencies set to true also failed me.

.
Your guidance would be more than welcome.

Your packages dependencies are a bit strange.
After installing the problematic package individually, try installing dlookr.

install.packages("TTR")
install.packages("curl")
install.packages("systemfonts")
install.packages("gfonts")
install.packages("svglite")
install.packages("quantmod")
install.packages("gdtools")
install.packages("tseries")
install.packages("xml2")
install.packages("rvest")

and

install.packages("dlookr")
