Hi, thanks for this.
Sadly, reproducing this is totally random and can't be done.

Also, "mgaapplet" can't be reliable when distribution is set to Cauldron.
Usage is not recommended until it enters feature freeze.

For 2 main reasons:
 - mirror synchronization can take a while when new/updated packages are sent to repositories.
 - new/updated packages can have new dependencies to be computed and to be installed whereas they are in processing building in Build System.

We acknowledge that a better "user-friendly" tip can be displayed.

One solution: try again later after do a "urpmi --clean" before attempting to update again.

Please close mgaapplet tray icon by right-click on it and choose "Quit".
Do in a terminal:
$ mgaapplet -vv --debug &

And add output here.
Leaving this in Bugsquad until further notice.

It seems that there is no more error and all repositories have been correctly updated.
We know that this is very weird when such "crash" occurs.


Since this is reported against Cauldron (advice in Comment 1)
and mirror http://ftp.fi.muni.cz/pub/linux/mageia/distrib/cauldron/ is well synced
(https://mirrors.mageia.org/status)
and this is no more reproduced, but we agree that a more "user-friendly" error message can be added.

Assigning to Maintainers.

A crash can be a security issue. Such security issues are usually severe. I believe you should definitely care.

Severity: enhancement => minor
