I don't understand at all what I'm doing, but I've decided that I want to uninstall QPDF. So, I went to "Stup" "Remove builtin packages" and uninstalled it. I regretted it, so I went to Puppy's package manager and tried to reinstall QPDF. I tried several things but it didn't work.
At one point, the program opened but said "there was no plugin to open PDF".
Then it didn't open anymore. I went to the terminal and typed "qpdf", it replied that there was an error loading the library "libqpdf.so.29".
The qpdf packages are here:
https://packages.ubuntu.com/focal/qpdfview
I don't understand anything I'm doing, so "calm down". I'm starting in the Linux world.
Thanks
