@Tartaros said in bq Aquaris E5 HD Ubuntu Edition wants to be OEM unlocked during installation:

@Lakotaubp I expect I need to switch the device to fastboot mode prior to performing the OEM unlock? I will try it tomorrow.

In theory yes, snaps can be run with Manjaro, but the snap support is still experimental and I do not want a snap error to make my phone a pricy paperweight.

You can try the appimage it works well.
I just tried today the snap installer since the aur package was giving me the same error as yours and it worked flawlessly.
