我一直尝试在 Ubuntu 23.04 上安装 R，但出现以下错误：
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base-core : Depends: libicu70 (>= 70.1-1~) but it is not installable
Depends: libtiff5 (>= 4.0.3) but it is not installable
E: Unable to correct problems, you have held broken packages.
我该如何解决这个问题？
