@erikescudero different user with the same problem. When running MC 1.7 on terminal I get a “libpng warning: iCCP: known incorrect sRGB” however MC does run but is unable to update on its own.
Then after patching it with MC 2.deb it installs fine but MC will not open. Terminal shows a long long error “Requested graphicsModr not available: OpenTK graphics...” “...Thread was being aborted”
