Generate document failed when installing package on Ubuntu18.04

[ngoan1608]

Hi,

I faced the issue on generating package's document for this repo when working with build pipelines.
The error happens only on OSD5 with Ubuntu version 18.04, other environments works fine.

I have looked into the log but cannot find the solution (missing packages, wrong version, ...) now.
Log on console as below:

exlive/2022/texmf-var/fonts/map/pdftex/updmap/pdftex.map}]

I have tried to build many times and found that the generation of document still worked fine with commit 60da3d0.
Then, from commit 306e5eb, the issue comes.

Please help to verify your changes which impact to the document's generate or something is missing (related to Texlive) on OSD5 runner.

Thank you,
Ngoan
