But some government bodies that have made the move regretted it and ended up crawling back to #Windows. #Vienna released the #Debian-based distribution #WIENUX in 2005 but gave up on migration by 2009.

In 2003, #Munich announced it would be moving some 14,000 PCs off #Windows and to #Linux. In 2013, the #LiMux project finished, but high associated costs and user dissatisfaction resulted in #Munich announcing in 2017 that it would spend the next three years reverting back to #Windows.

#Albrecht in 2021 addressed this failure when speaking to Heise, saying, per #Google's translation:

The main problem there was that the employees weren't sufficiently involved. We do that better. We are planning long transition phases with parallel use. And we are introducing open source step by step where the departments are ready for it. This also creates the reason for further rollout because people see that it works.
