To Reproduce

  • 根据pjbrunet的描述，我在var/lib/pacman/sync该路径下看到了sig文件并把它们删掉，pacman可以正常使用了，但pamac并没有。我再次使用pamac更新软件时，该路径下依然会产生‘.sig’文件，同样的操作在手机热点下结果一样，所以我并不确定是我的网络问题还是pamac的问题。
  • According to pjbrunet, I saw the ‘.sig’ files in var/lib/pacman/sync and deleted them , pacman works fine but pamac does not. When I used pamac to upgrating the software again, the '.sig’files was still generated in this path. The same operation had the same result with my mobile’s wifi , so I wasn’t sure if it was my network or pamac .

System information

  • OS: Manjaro Gnome 40
  • pamac version: 10.1.3-3
  • Pacman: v6.0.0 - libalpm v13.0.0

Additional context

  • network: campus network
  • mirrorlist: global (refresh frequently)

My problem is the same as this :

I tried the solution, and I got this problem . The invalid or corrupted database (PGP signature) is still

In fact, I’d like to know what causes this kind of problem is so common ?

There are many factors. Incorrect system time, your ISP blocked the port used to import PGP keys, etc. Check out this ArchWiki:
pacman/Package signing - ArchWiki (archlinux.org)
