问题
My MacOS App Store does not work correctly. It is not possible to install updates or install apps from the store.
I suspect it has something todo with the following error message, which is repeated several times in /var/log/install.log.
2019-03-26 21:26:08+01 My-MBP softwareupdated[27061]: softwareupdated: Starting with build 10.13.6 (17G65)
2019-03-26 21:26:08+01 My-MBP softwareupdated[27061]: Couldn't retrieve private cache directory path: 5.
An indication is as well in my eyes, that the cli softwareupdate also does not work. Same for mas (https://formulae.brew.sh/formula/mas#default).
All programms: App Store, softwareupdate, mas behave basically in the same way. After the start nothings happens. E.g:
App store
starts up. When I click on the icon updates the "rainbow spinner" appears and the app freezes. Same when I try to install an App. I can close the App Store only if I do a killall "App Store"
mas
mas install 425424353

# Nothing happens
softwareupdate:
softwareupdate -l
Software Update Tool
Finding available software
# Nothing happens
Does someone have a hint, how I could fix this problem with the missing private cache directory?
Some information:
- OSX 10.13.6 (on a macbook early 2011)
- App Store 2.4 (658.1)
- softwareupdated: Starting with build 10.13.6 (17G65)

Checking /var/log/system.log I discovered the following line:
Aug 11 09:50:33 My-MBP softwareupdated[516]: libcoreservices: _dirhelper: 666: mkdir: path=/var/folders/zz/zyxvpxvq6csfxvn_n00000s0000068/C/softwareupdated/ modes[2]=0700: Permission denied
I did a chmod -R 777 /var/folders/zz and now it works. I could update my system. Furthermore the chmod ... fixed another issue I had with my mac.
