Bug ID: 516861
Summary: KDE Linux Alpha update aborts at ~97% due to /tmp
tmpfs size limit
Classification: Applications
Product: Discover
Version First unspecified
Reported In:
Platform: KDE Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: discover
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: ---
During system update via Discover on KDE Linux Alpha, the download repeatedly
aborted at around 97% without a visible error message in the GUI. Discover
showed “Unknown” as size and simply stopped.
Journal output from kde-linux-sysupdated showed:
write tcp 127.0.0.1:3129->127.0.0.1:xxxxx: write: broken pipe
Root cause was /tmp being a tmpfs (approx. 8 GiB) that was already partially
used (~6.3 GiB). The system image is ~6–7 GiB. When /tmp ran out of space near
the end of the download, the client side aborted the connection, which caused
the local sysupdate proxy to log broken pipe.
After clearing /tmp (freeing space to ~7.9 GiB available), the update completed
successfully without further changes.
Expected behavior:
If /tmp runs out of space during image download, Discover should show a clear
error message (e.g. “Not enough temporary disk space”) instead of silently
aborting.
Actual behavior:
Update aborts silently in Discover. Only journal shows broken pipe.
Environment:
KDE Linux Alpha in KVM VM
Btrfs root
/tmp mounted as tmpfs (size ~8 GiB)
Let me know if additional logs are required.
