这个问题似乎解决了这个问题https://askubuntu.com/questions/958355/any-app-on-ubuntu-to-open-and-or-convert-heif-pictures-heic-high-efficiency-i
但是在 Debian 上，添加所需的存储库失败：
# add-apt-repository ppa:strukturag/libheif
This PPA contains packages to add support for HEIC / HEIF files.
HEIF is a new image file format employing HEVC (h.265) image coding for the best compression ratios currently possible.
libheif is an ISO/IEC 23008-12:2017 HEIF file format decoder (encoder to come). It makes use of libde265 for the actual image decoding. Alternative codecs for, e.g., AVC and JPEG can be provided as plugins.
libheif has support for
- tiled images
- alpha channels
- thumbnails
- reading EXIF data
- reading the depth channel
- multiple images in a HEIF file
- image transformations (crop, mirror, rotate)
- overlay images
- plugin interface to add decoders for additional formats (AVC, JPEG)
See https://github.com/strukturag/libheif for further information.
NOTE: You will also need to enable the PPA "strukturag/libde265"
if you are running Ubuntu Trusty or older, so dependencies can be
resolved.

因此我不能使用这种方法。
还有其他方法吗？我只想从命令行将一组 HEIC 文件转换为 JPEG。紧急情况下，我可以启动 GIMP 并手动逐个转换它们。但是，即使是 GIMP 也无法读取这种格式。
