无法更新 R

Question

I have 4.0.2 version and I want to update it. So I install installr and I tried to use updateR() :

install.packages("installr")

library(installr)

updateR()

After library(installr) I got a warning message:

Installation status: FALSE . Removing the file:

C:\\Users\\HP250~1\\AppData\\Local\\Temp\\Rtmp2RQ7lv/R-4.0.3-win.exe (In the future, you may keep the file by setting keep_install_file=TRUE)

[1] FALSE

Warning messages:

1: In download_fun(exe_URL, destfile = exe_filename, quiet = FALSE, :

downloaded length 20258816 != reported length 88237960

2: In shell(install_cmd, wait = wait, ...) : > 'C:\\Users\\HP250~1\\AppData\\Local\\Temp\\Rtmp2RQ7lv/R-4.0.3-win.exe' execution failed with error code 1

but I continue with updateR() . Then it started loading but aftrer fe seconds (at 10-20%) stopped. I got an other warning message:

The setup files are corrupted. Please obtain a new copy of the program.

What is the problem? How can I fix it?

Thanks in advance!

I deleted Temporary Files and problem solved. I don't know why, but everything is ok now.
