Failed to generate thumbnail

LRR Version and OS
0.9.31 on ubuntu, install by source code

Bug Details
Failed to generate thumbnails for newly downloaded comic after updating to 0.9.31, with the error log below.

I dont find anymore error or warning, so please teach me how to find the log if needed.

Because of the needed for later version of perl, I manually update it. Then during the installation of LRR, I met lots of module missing error seems like: @inc (you may need to install the XXX module) , I manually install it one by one.
When updating LRR, the error log tell me the thumbnail will not work without ImageMagick, so I follow the given website to install it.
Finally everything seems well except thumbnail missing.

I try to change the thumbnail folder out of content folder and regenerate all thumbnail, the job just going on, with most job succeed and a few fail, but no thumbnail appear now.

You've installed PerlMagick manually? That's a recipe for trouble...

If the ubuntu vendor perl doesn't support 5.36, I would recommend switching to perlbrew and using Alien::ImageMagick to install the perlmagick bindings. See https://sugoi.gitbook.io/lanraragi/dev/installing-lanraragi/source#needed-dependencies.

[Difegue]

I would check beforehand if your imagemagick install actually works by running npm run lanraragi-installer install-back as well btw -- This will handle installing all the CPAN modules if there are any missing, and check if Magick support works as intended.

I am not using perlbrew because my os has pre-install low version perl, and I cant switch to the late version in perlbrew ( idk why ... ) . I am just install perl by source code and I guess this step is ok because most feature in LRR runs good.

I try install Alien::ImageMagick then using npm run lanraragi-installer install-back, the installation finish successfully, but the thumbnail still cant generate.
There are still some warning but seems unrelated to my problem, after following the guide I resolve it, here is the log.

I use convert -version to check image magick and its version is 6.9.11-60. The document say it should be 7.0 , is that causing problem?
Thanks for your guide and patient !

yeah you need v7, I can't remember off the top of my head why exactly, but it's a requirement.
