Posit Cloud免费版安装Tidyverse失败：rlang依赖404错误求助

环境：Posit Cloud免费版，R版本4.5.3（2026-03-11）

执行install.packages("tidyverse")时出现两类错误：

Warning: invalid package ‘/tmp/Rtmprr2mTv/downloaded_packages/rlang_1.1.7.tar.gz’
Error: ERROR: no packages specified

1: In .rs.downloadFile(url = c("http://rspm/default/__linux__/noble/latest/src/contrib/fastmap_1.2.0.tar.gz",  :
  cannot open URL 'http://rspm/default/__linux__/noble/latest/src/contrib/rlang_1.1.7.tar.gz': HTTP status was '404 Not Found'
2: In .rs.downloadFile(url = c("http://rspm/default/__linux__/noble/latest/src/contrib/fastmap_1.2.0.tar.gz",  :
  some files were not downloaded
3: In utils::install.packages("tidyverse") :
  installation of package ‘rlang’ had non-zero exit status

尝试加载库时执行library(tidyverse)报错：

Error: package or namespace load failed for ‘tidyverse’:
 .onAttach failed in attachNamespace() for 'tidyverse', details:
  call: NULL
  error: package or namespace load failed for ‘ggplot2’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 there is no package called ‘rlang’

单独执行install.packages("rlang")安装依赖包rlang同样失败，报错：

1: In .rs.downloadFile(url = urls, destfile = destfiles, method = "libcurl",  :
  downloaded length 0 != reported length 47
2: In .rs.downloadFile(url = urls, destfile = destfiles, method = "libcurl",  :
