After 1.22 was released, Ubuntu listed it in the daily 'Update'-program. But both 'geany' and 'geany-common' was unchecked in the list. There seemed to be no way to select them eiter.
Attempting to user 'Synaptic' for updating resulted in Synaptic just disappearing. /var/log/syslog reported a segfault:
kernel: [92547.705102] synaptic[17090]: segfault at 1 ip 00007f49be683c65 sp 00007fff160b8b00 error 4 in libc-2.13.so[7f49be63a000+197000]
The only thing that worked was removing geany using the commandline: 'sudo apt-get remove geany geany-plugins geany-common'
After that I could install 'geany' again, though quite a few of the plug-ins are now gone.
