Continuing to run and update MATE 16.04 PPC system on my PowerMac 3,1 G4 . . . generally all is well. However over several weeks and a number of large dist-upgrades a problem with opening the home & desktop folders from the “Places” drop down menu does not open the folder; instead GDebi package installer opens and then an error window opens saying “could not open ‘non_space’ . . . the package might be corrupted or you are not allowed to open the file. Check permissions of the file.”
Clicking on “computer” from the same list opens the folder, as does clicking on the desktop home folder icon . . . . Happy to file a bug report if that will help out, posting here first as per Martin’s request for reporting issues.
