Hello, I am new to mycroft and I have issues installing on Elementary OS 6.1 on my 2011 macbook air (also new to linux in general). Elementary OS 6.1 is built on Ubuntu LTS 20.04.3
I’ve searched for a thread that expressed similar issues [here](https://community.openconversational.ai/t/fatal-error-when-installing/9355) but it appeared to be a distro-specific issue (Manjaro) for that user and I did not find a solution that worked for me there. I would appreciate any help here. I went with the recommended git installation.
I ran bash dev\_setup.sh and my error logs are below; I did not have issues up until this point:

Run the following and re-run ./dev-setup.sh
```auto
ln -s /bin/gcc /bin/gcc-5

Thank you! There was a similar issue with g++ as but these were fixed after running your suggested code to establish the right linkages (to gcc-5 and g+±5).

Not sure if it’s right to continue this thread since it is a separate issue from the above, but I’m now facing another set of issues after resolving the issues with dependencies. This is the error log when trying to compile mimic:

Edit: Upon researching the issue further, it appears someone found a similar issue with compiling mimic [here](https://github.com/MycroftAI/mycroft-core/issues/2511). The suggested solution was to skip the mimic build, or to [try an unofficial repo with mimic](https://forslund.github.io/mycroft-desktop-repo/).

Update:
I have fixed all above issues. I installed Mycroft via the Synaptic Package Manager using the [unofficial Mycroft Desktop](https://forslund.github.io/mycroft-desktop-repo/) install, and this solved all my problems.
For those that experienced multiple issues with their install, this might be an amenable solution to you. I tried the snap store snap, it didn’t work well. The package manager instead was helpful. I’m not sure why this alternative was not included in the documentation - in any case I hope others find this useful.
Again, thanks @AIIC for the prompt and generous help.
