Pamac can't find software installed with pacman

[ecavicc]

I’ve always used pacman + octopi, but I would like to start using pamac because of the snap and flatpak plugins. As far as I know, pamac and pacman should share the same database and be completely compatible, but it doesn’t seem like it.

For example, trying to install the package sl, I get this output from pacman

$ sudo pacman -S sl

Packages (1) sl-5.02-6

Total Installed Size:  0,03 MiB

:: Proceed with installation? [Y/n]

and this output from pamac

$ sudo pamac install sl

Apply transaction ? [y/N]

If I search for glibc using pamac search -i glibc, though, pamac is able to find it.

Also, if I try to use pamac to uninstall a package installed through pacman, I get this error

$ sudo pamac remove sl
Preparing...
Error: Failed to prepare transaction: target not found: sl
Error: Failed to prepare transaction: target not found: sl

Any ideas about what’s wrong? Or am I just missing something?

I installed sl with pacman, then I removed it with pamac, no issue there :\

//EDIT: note that I’m on TESTING branch so there might have been an update, try the TESTING branch to check it out.

Switching to testing branch apparently solved the issue. Might as well abandon stable, since I’ve been thinking about switching for some time. Thanks!

[omano]

To be honest, no regret since I switched to Testing, I have updates earlier than Stable, and basically it is as stable. Only thing is that I try to follow the Unstable announcement threads because what is broken on Unstable can sometimes land on Testing, and of course read, and report any issue on Testing announcement threads.
