Thanks for the hint; you called it exactly. I had this in my apt preferences: Package: * Pin: release a=testing Pin-Priority: 900 Package: * Pin: release o=Debian Pin-Priority: -10 ... and I'm currently still on Buster, having not moved on to Bullseye yet. - Ted

libfuse3-dev is a virtual package?
So this is weird. I can't install libfuse3-dev on my buster system: # apt install libfuse3-dev Reading package lists... Done Building dependency tree Reading state information... Done Package libfuse3-dev is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'libfuse3-dev' has no installation candidate Apt seems to think it is a virtual package: # apt show libfuse3-dev Package: libfuse3-dev State: not a real package (virtual) N: Can't select candidate version from package libfuse3-dev as it has no candidate N: There is 1 additional record.
