dpkg: error: cannot access archive ‘erlang-solutions_1.0_all.deb’: No such file or directory

Did I miss osmething?

My mistake. I have got past that.
Now I have ** (SyntaxError) config/dev.exs:62: unexpected token: “$” (column 29, code point U+0024). The $ is there for the pattern matching at the end of the line, so how can that be wrong?

Hey Pisicuta, can you posted your config/dev.exs? Otherwise, you can try to use default config/dev.exs from any phoenix github project. My sense, there is something small typho there.
