Install/update fails in Cydia (red/yellow text)

Fix red errors caused by insufficient system partition space​

If the red text contains any of the following: No space left on device cannot copy extracted data for failed in buffer_write(fd) (8, ret=-1) Your system partition may be out of space. Try uninstalling unnecessary tweaks or removing useless resources. Do NOT delete /.cydia_no_stash to free space, or you may brick the device.

Possible fix for iOS 9.2 ~ 10.2.1 (not 9.3.5)​

  1. Plug in power and keep it powered. Remove all sources except Cydia/Telesphoreo and XXTouch (no loss, don’t worry).
    • Tap “Sources” → top-right “Edit” → tap the red minus icon in front of a source
  2. Add the source apt.abcydia.com (Leifeng repo)
  3. In Cydia choose to uninstall Cydia Substrate and take a screenshot of the uninstall list. Do NOT confirm yet. Read the next lines carefully:
    • This will also uninstall many tweaks including XXTouch. In theory it’s safe, but we won’t take responsibility; if concerned, stop here and consult a trusted professional.
    • After understanding the above, decide whether to confirm uninstall.
  4. Search and install the tweak “Stashing 容量不足修正”
  5. Now you should have plenty of space. If needed, reinstall what was removed in step 3.

Possible fix for iOS 9.3.5 jailbroken via Phœnix​

  1. Plug in power and keep it powered. Remove all sources except Cydia/Telesphoreo and XXTouch (no loss).
    • Tap “Sources” → top-right “Edit” → tap the red minus icon in front of a source
  2. Add cydia.angelxwind.net (Karen/angelXwind) and apt.abcydia.com (Leifeng)
  3. In Cydia choose to uninstall Cydia Substrate and take a screenshot of the uninstall list. Do NOT confirm yet. Read carefully:
    • This will also uninstall many tweaks including XXTouch. In theory it’s safe, but we won’t take responsibility; if concerned, stop here and consult a professional.
    • After understanding the above, decide whether to confirm uninstall.
  4. Install “Stashing 容量不足修正” and “Stashing Fix for Phœnix (9.3.5)”
  5. Reboot as prompted
  6. Re-activate jailbreak, space should be sufficient. Reinstall what was removed in step 3 if needed.
