Sometimes I get a lot of ‘package not found on AUR’ messages or packages failing to install/build from AUR.
This is currently happening on my Antergos-Gnome machine but not on my Antergos-KDE laptop.
For example vivaldi-ffmpeg-codecs built & installed fine on my KDE rig but completely fails to install on the Gnome one. I also tried the Vivaldi Netflix script which worked on the KDE unit but failed on the Gnome one with loads of ‘failed to write to’ errors.
I have refreshed the mirrors but with no improvement.

I have a feeling the install system has gone a bit awry on my Gnome machine.
Is there a way to clear any cache that may be causing a problem i.e. a way to reset the package manager/install system?

Thanks in advance :-)
