QGIS is a largely volunteer driven project, and is the work of a dedicated team of developers, documenters, translators and supporters. Despite the efforts of the team to release QGIS without bugs, there may remain some bugs. If you find a bug or want new features to be added, please report it!
Each part of the QGIS Project has a dedicated place where issues (feature requests or bugs) can be reported, managed and discussed. Depending on the area you encountered the issue, the table below indicates the right repository to report it:

QGIS applications (QGIS Desktop and QGIS Server) issues are available in Github. In order to submit or comment a report, you need to register and login.
Before filing an issue, verify that you are running the currently supported versions 3.22.10 or 3.26.2 or the development version 3.27 (see also Calendário de lançamento) and review the currently open issues to make sure that you aren’t creating a duplicate. If you have additional information on an issue, you can add it to the existing ticket. Third party plugins might also cause problems. If you have installed any, you should also verify that the problem is still reproducible without them. Please don’t report multiple unrelated bugs in a single bug report.
When you’re are logged in, a
New Issue button is available. Select it and
follow the instructions there.
Before sending the report, please check the formatting of your report by clicking on «Preview». Please avoid editing existing reports, if not for typos. Better add further comments in any other case.
If you have a crash it might be useful to include a backtrace as the bug might be not reproducible on another machine.
On Linux QGIS automatically tries to use
gdb to connect to the crashing
process to produce a backtrace. But some distributions disable the possiblity
to connect debuggers to a running processes. In that case
produces a rather useless message like:
QGIS died on signal 11Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Operation not permitted. No thread selected No stack. gdb returned 0 Aborted (core dumped)
In that case you should reenable that option by setting
kernel.yama.ptrace_scope to 0 in
/etc/sysctl.conf or some other file in
sysctl -p as root. When you reproduce the crash after that,
a backtrace will be printed instead.
If you cannot reproduce the crash, there should still be a core dump in the
current directory, that can be analysed after the process has already
terminated. It’s called
core (on some systems a dot and the process id is
append to the filename).
On some distributions the creation of core dumps is also disabled. In the
event that you just get
Aborted instead of
Aborted (core dumped) when the
crash occurs. Then you need to run
ulimit -c unlimited before starting QGIS.
You can also include that in your
.profile, so that it’s always enabled when
To produce a backtrace from the core file, start
/path/to/the/qgis/binary core. The binary is usually
/usr/bin/qgis.bin on Debian with the GRASS plugin installed. In
bt which will produce the backtrace.
The nightly build in OSGeo4W (package qgis-dev) is built with debugging output, that you can view with DebugView. If the problem is not easy to reproduce the output might shed some light about where QGIS crashes.
QGIS project provides an active web site and a rich documentation. Despite our efforts, if you find an out of date information, a wrong or unclear statement or miss a valuable information, please feel free to report it.
The main sources of these documents are hosted and managed in GitHub repositories so in order to report bugs or submit patches, you need a GitHub account and login.
To get started, first Create a GitHub account.
Then, choose the appropriate repository:
https://github.com/qgis/QGIS-Documentation/issues for QGIS documentation
https://github.com/qgis/QGIS-Website/issues for the web site
Check if the issue you’d like to report is not already entered.
Click New Issue, type a title and a clear description for your issue.
When you’re finished, click Submit new issue.
Fix me link is provided at the bottom of any page of the web site
to help you directly improve this page and submit pull request.
This option is also available in the footer of the documentation.
Most of the plugins in QGIS are published in the official QGIS Plugins repository. Bugs or feature requests relative to them must be opened in their respective bug tracking system:
For any plugin available in QGIS repository, you’ll find in its metadata a link to its bug tracker. Otherwise, consult the plugin documentation to find the address of the relevant bug tracking system or a developer to contact.
If no information is available, please report it to the Developer mailing-list.
For other plugins, we have no means to ensure such information are provided.
In addition to issue report, you can help to fix issues. Fixing issues is done in GitHub through pull requests. You need to fork the repository you want to contribute to and submit pull requests at:
