Install package undertilde

Question

I want to install the package undertilde.

When I try to install using method 1 as given in the answer to the question

How do I install an individual package on a Linux system?

i.e. using tlmgr - I get the following errors.

Cannot determine type of tlpdb from /home//texmf!

cannot setup TLPDB in /home/****/texmf at /usr/bin/tlmgr line 6424.

if your tex is the linux supplied one not installed directly from tug use your package manage yum or dnf or whatever you use for linux updates — David Carlisle, Nov 10 '21 at 09:02
As David says, sadly the Linux fists cripple tlmgr so it can no longer install packages (their distribution system, their choice). If you're on a Debian/apt based system you can install apt-file and use it to ask Debian which Debian package provides the file undertilde.sty — daleif, Nov 10 '21 at 09:32
@daleif if you mean
apt-file search undertilde.sty

It yields nothing. — Dr. Akash Dixit, Nov 10 '21 at 11:18
@DavidCarlisle I am sorry, I do not understand. Could you please be more specific? — Dr. Akash Dixit, Nov 10 '21 at 11:20
Well given that CTAN lists that only MikTeX have undertilde (https://ctan.org/pkg/undertilde) that is not a surprise, then it is not available via Linux dists (as they use TeXLive) or via tlmgr (for whose using a tlmgr that works) — daleif, Nov 10 '21 at 11:25
If you absolutely need something that has not been updated since 2000!!!! Then you'll need to manually get the .ins and .dtx from https://ctan.org/tex-archive/macros/latex/contrib/undertilde and run latex on the .ins file. But I would suggest you look somewhere else for a solution to whatever problem it it you want to use undertilde to solve. — daleif, Nov 10 '21 at 11:55
Given that it has not been updated since 2000, there is no guarantee that it will work with modern LaTeX installations. — daleif, Nov 10 '21 at 11:57
Which exactly is your operating system/distribution? (read their documentation, they may have specific instruction to install TeX packages) — user202729, Nov 10 '21 at 13:22
I would probably have a look at the accents package instead. — daleif, Nov 10 '21 at 14:11
@user202729 that does not help when the package is not available for TeXLive — daleif, Nov 10 '21 at 14:11
accents - Sub tilde in LaTeX - TeX - LaTeX Stack Exchange // packages - Why is undertilde.sty not found? - TeX - LaTeX Stack Exchange — user202729, Nov 10 '21 at 14:21

After struggling a bit and with help of comments above, I came to the conclusion that using undertilde package itself is a problem. As @daleif noted that the package has not been updated since 2000. Therefore, the solution is to use some other package to obtain the functionality of the undertilde pacakge.

Specifically, I was using the \utilde command from the undertilde package. I was able to do that using \underset command. For example, if I needed a tilde beneath r, I will write \underset{\sim}{r} to substitute \utilde{r}.
