Help for installing LaTeX

Dear,
I’m following the guides to install letex.
https://docs.getindico.io/en/stable/installation/latex/#latex

After I do the following:
./install-tl – profile texlive.profile.
the following error is printed on the screen:

Can't locate Digest/MD5.pm in @INC (@INC contains: ./tlpkg /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at tlpkg/TeXLive/TLCrypto.pm line 9.
BEGIN failed--compilation aborted at tlpkg/TeXLive/TLCrypto.pm line 9.
Compilation failed in require at ./install-tl line 155.
BEGIN failed--compilation aborted at ./install-tl line 155.

How do I need to fix this error?

Add some information:

  • Indico version installed (3.2.3)
  • Python version used (3.9.16)
  • Postgres version used (13.10)
  • Operating system used (CentOS Linux 7)

Make sure the corresponding perl package is installed:

yum install 'perl(Digest::MD5)

Yes, perl(Digest::MD5) should be installed before installing LaTex. I’ve completed the installation.
Thank you very much!
