Cydia Errors

Cydia.app includes many error messages that might not be easy to understand at first, including error messages that are directly from Debian APT. Here are explanations for them. (This is also covered in the JailbreakQA FAQ.)

Could not get lock /var/lib/apt/lists/lock - open (35: Resource temporarily unavailable)
Could not get lock /var/lib/apt/lists/lock - open (35: Resource temporarily unavailable)

Cydia temporarily can't refresh data because another program is already using a system component that Cydia needs. This error commonly happens if you're also using another program that refreshes package data, such as Curiosa. To fix it, try rebooting. If that doesn't help, you may need to uninstall Curiosa (and any other packages that do this).

Cydia ran into some kind of network problem. The usual cause of this error message is using packages that add tons of ad-blocking lines to your hosts file; uninstalling those packages should fix this error.

Cydia tries to fix this problem automatically. If this is the only error message displayed, you can ignore it and use Cydia normally.

One or more of your installed sources is set up incorrectly. You should be able to remove the problematic source by going to Sources and tapping "Edit" at top right. If you are not sure which one to remove, try removing all of them except the defaults (BigBoss, Cydia/Telesphoreo, Dev Team, ModMyi, and ZodTTD/MacCiti).

There is not enough disk space (on the system or user partitions or both) for Cydia to install this package. Try removing some files first, such as large bootlogo or theme files; you may need to use iFile, OpenSSH, or some other way to access the filesystem. You can also check iFile's trash folder (/var/mobile/Library/iFile/Trash). You can go to the Cydia homepage and tap "Storage Information" to check available space on both the system and user partitions.

GPG error: [repository] stable Release: The following signatures were invalid: BADSIG [number]

This is a minor problem with a source. You did nothing wrong and can continue to use Cydia normally.

GPG error: [repository] stable Release: The following signatures were invalid: NODATA 1 NODATA 2
GPG error: [repository] stable Release: The following signatures were invalid: NODATA 1 NODATA 2 Failed to fetch [repository] Sub-process /bin/bzip2 returned an error code (2) Some index files failed to download, they have been ignored, or old ones used instead.

One or more of your installed sources is temporarily or permanently unavailable. You may have typed in the wrong URL, the source may have shut down, the source may be broken, or the source may be denying your connection for some other reason. Try again later. If this problem keeps happening over many days, you can remove the problematic source by going to Sources and tapping "Edit" at top right.

Hash Sum mismatch
Hash Sum mismatch

The downloaded file does not match the file on the source's server. This is often caused by a download getting interrupted before it finished, sometimes due to network problems and sometimes due to server problems. Try installing this package again later.

Host Unreachable
Host Unreachable

This may mean that your internet connection is not working, a source is not working, or something else is not working (such as the Cydia Store system). This is probably a temporary problem, so try again later.

HTTP/1.0 403
'''HTTP/1.0 403 This package is either paid or requires a paid package to function. If you paid: contact saurik@saurik.com for help. If not, purchase the original package.'''

If you get this error while trying to download a paid package you have already purchased, email saurik@saurik.com for help. If you are trying to download a paid package you have not purchased, buy it and then try downloading it again. If you are trying to download a free add-on to a paid package (for example, a package adding a new option to Color Keyboard), you have to purchase that paid package before you will be able to download this add-on.

Something seems to be wrong with the source hosting this package. This is probably a temporary problem, so try again later.

I wasn't able to locate file for the [package] package. This might mean you need to manually fix this package.
'I wasn't able to locate file for the [package]'' package. This might mean you need to manually fix this package.'''

Something weird went wrong. Try going to the Changes tab, tapping "Refresh" at top left, waiting for data to finish downloading, and then installing this package again.

POSIX error: Operation Timed Out. POSIX: Socket is not connected. NetDB: Open nodename nor servname provided, or not known.

Cydia is working properly, but something is wrong with your device's connection to one or more of your installed sources. Your internet connection may not be working properly, or the source may not be working properly. Check your internet connection and try again later.

One or more of your installed sources is set up incorrectly. (This is a problem with that source, not with Cydia.) You should be able to remove the problematic source by going to Sources and tapping "Edit" at top right.

Something seems to be wrong with this package. Tap "Author" at the top of the package page and email the developer (and ideally the repository manager as well) to let them know about the problem and ask for help.

You are trying to install a new package that contains the same filenames as a package you already have installed, so you cannot install this new package. You can usually avoid this problem by avoiding (or uninstalling) illegally copied versions of packages.

Wow, you exceeded the number of package names this APT is capable of.

This happens if you are using an old Cydia version (before 1.1.10) and have packages available from your installed sources. Make sure you are using the latest version by refreshing your sources and updating all relevant packages.
