To Reproduce

1. Run g.extension extension=i.wi

Expected behavior
Well, the addon should be installed properly.

Additional context
I report here as an i.wi issue because other addons install just fine, i.e., i.eodag, i.sentinel, etc.

[ecodiv]

I can confirm this for 8.4 on Ubuntu 24.04 (Linux 6.8.0-48)

[petrasovaa]

I believe this should be reported as g.extension bug, I think perhaps bug in some regular expressions in get_multi_addon_addons_which_install_only_html_man_page.

[veroandreo]

Shall I transfer the issue then? Dunno if I have permission for that.

It seems that the installation process of i.wi addon it works as expected now (tested with 8.5.0dev version, revision 231bb51, Gentoo GNU/Linux distribution):

It indeed installs on 8.5.0dev (5c1ea4a) on Ubuntu 24.04. There is still a warning, but it gets installed.

[veroandreo]

Indeed it installs, though it is not clear that it installs because it yields the error and not the "successfully installed extension" message.
