Why some R packages can't be installed - r

Question

I've been using R for a while and everything was normal when installing packages. Recently, I upgraded R on my Ubuntu 16.04 from 3.4.4 to 4.0.2 and then I tried to install the package imputeTS as
> install.packages("imputeTS")
Installing package into ‘/home/.../R/x86_64-pc-linux-gnu-library/4.0’
(as ‘lib’ is unspecified)
also installing the dependencies ‘png’, ‘gridtext’, ‘ggtext’

Then
> library(imputeTS)
Error in library(imputeTS) : there is no package called ‘imputeTS’
I tried to install the same package as install.packages("imputeTS", dependencies = TRUE) but this gave me the same result installation of package ‘imputeTS’ had non-zero exit status
Following, I tried to install the packages Hmisc and mice. The same result was for the first package where as mice was installed successfully!
Two more comments, the first is this statement (as ‘lib’ is unspecified) started to appear just after upgrading R. The second, I am not sure if related, is that there is no space on my linux!
So how could I install the needed packages successfuly?

Answer 1

Just a wrap up that people can find the correct answer given in the comments better and understand the error messages
This is no problem related specifically to the imputeTS package.
This can be seen in this part of the error message
Error: package or namespace load failed for ‘png’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/home/.../R/x86_64-pc-linux-gnu-library/4.0/00LOCK-png/00new/png/libs/png.so':
libpng16.so.16: cannot open shared object file: No such file or directory
The error actually occurs while trying to install the png package.
How is this related to the imputeTS package?
You can see this here:
ERROR: loading failed
removing ‘/home/.../R/x86_64-pc-linux-gnu-library/4.0/png’
ERROR: dependency ‘png’ is not available for package ‘gridtext’
removing ‘/home/.../R/x86_64-pc-linux-gnu-library/4.0/gridtext’
ERROR: dependency ‘gridtext’ is not available for package ‘ggtext’
removing ‘/home/.../R/x86_64-pc-linux-gnu-library/4.0/ggtext’
ERROR: dependency ‘ggtext’ is not available for package ‘imputeTS’
removing ‘/home/.../R/x86_64-pc-linux-gnu-library/4.0/imputeTS’
R packages build on each other and import functions of other packages. In this case imputeTS imports ggtext, which imports gridtext, which imports png.
So quite a sequence of dependencies and if installation of png fails, this affects all the other packages.
Luckily this part of the error message also gives a hint, what could be wrong:
unable to load shared object '/home/.../R/x86_64-pc-linux-gnu-library/4.0/00LOCK-png/00new/png/libs/png.so':
libpng16.so.16: cannot open shared object file: No such file or directory
There is a library missing on which the png package itself depends on. Without this library the installation of png will fail and cause all these mentioned issues.
So just install the library like this:
sudo apt-get install libpng16-16
