Memory cache question when upgrading


I got the following message in terminal when upgrading:

51 packages to upgrade. 
Overall download size: 19.7 MiB. Already cached: 0 B. After 
the operation, additional 167.7 KiB will be used. 
**Continue? [y/n/? shows all options] (y): **y

Just wondering which memory type is being used and how do I increase its size? Last week some packages were not being installed because there was insufficient memory in the cache. Today I have already increased the sizes of my root and home partitions but it seems they are not relevant because I still see the above message after resizing the partitions.

Thanks a lot for your help. I look forward to hearing from you.

Just done that update myself, that’s an ordinary message, nothing odd.
The “cache” mentioned is the “zypper cache”: when you start downloading, packages go to the “zypper cache”, from which they are taken when actually installed.
If you aborted the update at the end of the download phase, but just prior to actual install, you were going to read:
“Overall download size: 0 B. Already cached: 19.7 MiB.” on the next update attempt.

If you were not able to update some packages last week, it was likely due to a full /root partition, where the “cache” sits at /var/cache/zypp/
So, by enlarging your /root, you “fixed” the cache problem as well…

Showing actual errors that you had would be helpful.
