do-release-upgrade broke WSL

[Artem Leshchev]

I had Ubuntu 17.04 installed in WSL and decided to upgrade it to 17.10, so I had run do-release-upgrade, as I did before to upgrade to 17.04. Everything was fine before script started upgrading packages. It's started from bash updating, and somehow there is a problem revealed that locale files is missing, and locale-gen can't be run (because of bug in WSL). I've tried to install language-pack-en as was suggested, but problem haven't resolved, any attempt to update leads to this error.

Please set as fix released only with a fix somewhere, I can't see how and who fixed it

[Andrew St Clair (st0ner1995)]

can we get instructions on how to fix our installs? running apt to update and upgrade returns errors and breaks because of the locale issue

[Caleb Martin (belac1186)]

Where is this fixed? do-release-upgrade still fails with the same error in WSL and breaks it.

[Andrew St Clair (st0ner1995)]

i dont believe so,

i had to uninstall WSL and reinstall it

from an admin command prompt i ran

`lxrun /uninstall /full`

then

`lxrun /install`

or, if you want the default user to be root without a password

`lxrun /install /y`

This issue was also reported at the WSL GitHub project:
https://github.com/Microsoft/WSL/issues/2615

The reason seems to be a bug in glibc that has been fixed a few months ago:
https://sourceware.org/bugzilla/show_bug.cgi?id=22273

To fix this we need this patch for glibc in 17.10.

17.04 and 17.10 are both EOL and no further updates can or will be made there. For people still attempting to upgrade WSL, the best option is probably just to start fresh with an 18.04 WSL install.
