mh, i don't know exactly about thunar and pcmanfm (i don't use any file manager on my machines, always commandline tools) but maybe they require some packages, like 'gvfs' 'fuse-utils' 'gvfs-backends'
(is squeeze armel incompatible with "easy debian"?).
"The following packages have unmet dependencies: fusesmb: Depends: samba-common-bin but it is not going to be installed initscripts: Breaks: rsyslog (< 5.8.2-2) but 4.4.2-1 is to be installed libasound2: Breaks: libasound2-plugins (< 1.0.24) but 1.0.21-3 is to be installed libglib2.0-0: Breaks: gvfs (< 1.8) but 1.6.4-3 is to be installed libpolkit-backend-1-0: Breaks: policykit-1 (< 0.99) but 0.96-4+squeeze2 is to be installed libpolkit-gobject-1-0: Breaks: policykit-1 (< 0.99) but 0.96-4+squeeze2 is to be installed In sources.list, I have every repo un-commented, which is how I updated pcmanfm (through sid) to 0.9.7 in the first place. But it seems that these installations are wishing for older libs.
In sources.list, I've commented-out everything except: deb http://http.debian.net/debian wheezy-backports main [..] But when I try: apt-get -t wheezy-backports install pcmanfm I get a million complaints about dependencies that can't be upgraded to the new pcmanfm. Konqueror, jags, and komba2 are not available. Have I hit a wall? Or is there another workaround?
