Public bug reported: I installed `Ubuntu 20.04.1 LTS` few weeks ago. So it's almost fresh install.
I can't install libc6-dev: The following packages have unmet dependencies: libc6-dev : Depends: libc6 (= 2.31-0ubuntu9) but 2.31-0ubuntu9.1 is to be installed Here's what version the `-dev` package is: $ apt show libc6-dev Version: 2.31-0ubuntu9 Depends: libc6 (= 2.31-0ubuntu9), libc-dev-bin (= 2.31-0ubuntu9), linux-libc-dev, libcrypt-dev `Depends: libc6 (= 2.31-0ubuntu9)` looks good to me. apt-cache shows libc version is ok: $ apt-cache show libc6 Version: 2.31-0ubuntu9 However, `apt` differs: $ apt show libc6 Version: 2.31-0ubuntu9.1 apt can not tell where this version comes from `focal/main`: $ apt policy libc6 libc6: Installed: 2.31-0ubuntu9.1 Candidate: 2.31-0ubuntu9.1 Version table: *** 2.31-0ubuntu9.1 100 100 /var/lib/dpkg/status 2.31-0ubuntu9 500 500 http://us.archive.ubuntu.com/ubuntu focal/main amd64 Packages 9.1 can only be found in `/var/lib/dpkg/status` however, neither in packages here: `http://us.archive.ubuntu.com/ubuntu/dists/focal/main /binary-amd64/` nor in `/var/lib/apt/lists/us.archive.ubuntu .com_ubuntu_dists_focal_main_binary-amd64_Packages` version `2.31-0ubuntu9.1` does not exist. Upgrade can be seen in the logs: 2021-01-02 21:02:03 startup archives unpack 2021-01-02 21:02:03 upgrade libc6:amd64 2.31-0ubuntu9 2.31-0ubuntu9.1 2021-01-02 21:02:03 status half-configured libc6:amd64 2.31-0ubuntu9 2021-01-02 21:02:03 status unpacked libc6:amd64 2.31-0ubuntu9 2021-01-02 21:02:03 status half-installed libc6:amd64 2.31-0ubuntu9 2021-01-02 21:02:03 status unpacked libc6:amd64 2.31-0ubuntu9.1 2021-01-02 21:02:04 startup packages configure 2021-01-02 21:02:04 configure libc6:amd64 2.31-0ubuntu9.1 <none> 2021-01-02 21:02:04 status unpacked libc6:amd64 2.31-0ubuntu9.1 2021-01-02 21:02:04 status half-configured libc6:amd64 2.31-0ubuntu9.1 2021-01-02 21:02:04 status installed libc6:amd64 2.31-0ubuntu9.1 Is there a legitimate ubuntu repository with this package? How can I find the repository name where this package really came from? What worries me is md5s hash of this package is `1ec728d58f7fc0d302119e9bb53050f8` which can only be found on ropshell.
